Case Study Details

Clay was a popular material for drainage pipes in the United Kingdom from the early 20th century until the 1970s, when plastic became more widely used due to being easier and cheaper to fabricate and install.

High resistance to corrosion and chemical degradation gives clay extreme durability and longevity, with an estimated lifespan of anywhere between 60 and 100 years. This means many UK homes built before the 1970s are still serviced by working clay pipes.

One weakness of clay pipes, however, is they are susceptible to damage from root ingress and ground movement – which often only becomes obvious when a patch of ground becomes noticeably waterlogged from an underground leak.

A homeowner was carrying out building works when an area of their garden began suffering from this problem. After digging down, they discovered a dislodged 100mm clay pipe with two areas of significant damage.

The first and most severe was a crack next to a junction almost splitting the pipe into separate parts. The junction and uneven surface meant it would not be possible to reassemble the pipe using a repair clamp.

The clay pipe had a significant crack next to a junction with a smaller hairline crack along its top

Across the top of the pipe was a hairline crack, representing the second damaged area. There was no pressure and the homeowner was keen to avoid the cost and disruption which would come with replacing the pipe.

They therefore used a SYL-412-NP SylWrap Standard Pipe Repair Kit to seal the leaks and attach the pipe back together. Before the repair, enough room was dug out underneath the pipe to allow clearance for it to be wrapped.

The two cracks were then filled with Superfast Steel Epoxy Putty. Enough putty was first mixed by hand to cover the hairline crack. It was then pushed firmly down across the top of the pipe, curing within five minutes to form a rock hard material covering the leak.

For the larger crack, more putty was mixed and forced into the gap between the two sections of pipe. Once it had set, Superfast Steel bridged the crack with a watertight material bonded to both pieces.

The pipe was then overwrapped with SylWrap HD Pipe Repair Bandage. The fast-working resin in SylWrap HD was activated with water and the bandage wrapped along the entire length of the exposed pipe.

SylWrap HD cured to form a rock-hard, impact resistant protective shell. It reinforced the repair and helped hold the two broken pieces of clay pipe back together.

The homeowner said afterwards that the repair worked perfectly and that the product was great. Completing the repair took under 30 minutes and cost less than £50, representing a huge saving compared with removing the pipe and installing a replacement.

With many clay pipes installed before the 1970s now beginning to reach the end of their natural lifespan, repairs such as this are set to become more common in the UK over the coming years.

Case Study Details

The hose was connected to the engine, carrying water as part of the cooling process. Once the pinhole leak had developed, water was able to spray out at high pressure whenever the engine was in service. This was dangerous and unsustainable.

Repairing the leak was made challenging by the pinhole being located on a bend in the rubber hose. The hose itself was in a confined space below deck, surrounded by other pipes and engine components. A pipe repair clamp could not be fitted because of the constraints.

The hose was in a confined space making a repair difficult

The boat owner contacted Sylmasta seeking a versatile repair method capable of sealing the leak despite the difficulties in accessing the hose. A SylWrap Standard Pipe Repair Kit containing all the products needed to repair a pipe when pressure can be turned off was recommended for the application.

First, the pinhole was sealed using Superfast Steel Epoxy Putty. The putty was kneaded by hand and whilst soft, applied over the pinhole leak. It easily adhered to the rubber. After 5 minutes when the putty had started to harden, it was overwrapped using a SylWrap HD Pipe Repair Bandage.

SylWrap HD is a composite wrap with a water-activated resin, which sets rock hard in five minutes. As the Bandage was wrapped and smoothed around the hose, it forced the Superfast Steel as it cured further into the pinhole, completely sealing the leak. Once SylWrap HD had set, it formed an impact resistant sleeve to increase the repair’s effectiveness.

When used together, Superfast Steel and SylWrap HD create a repair with pressure resistance up to 30 bar and temperature resistance to 200ºC. When the boat engine was started, no water was escaping from the hose. The vessel could return to the sea.

Completing the boat pipe repair took under 30 minutes and cost less than £25, including delivering of the SylWrap Kit. This represented a significant cost saving compared to quotes offered by specialist marine engineering contractors to fix or replace the hose.

Case Study: External Surface Damage Repair to Restore Integrity of 400mm GRP Pipe

A GRP pipe suffering from external surface damage undergoes repair and strengthening with a Superfast Steel Epoxy Putty Stick

Repair damage now, avoid leak later – the oil refinery who reaped the benefits of external pipe surface restoration

When construction work revealed a 400mm GRP pipe suffering from areas of external surface damage, an oil refinery in Saudi Arabia decided to restore the integrity of the line to lessen the chances of a future breach requiring leak repair.

Case Study Details

Ongoing construction work at the oil refinery resulted in the excavation of an underground section of 400mm GRP pipe. The external surface of the line was discovered to be damaged, with two areas suffering from heavy scoring.

Although the pipe was not yet leaking, the refinery were concerned that the weakening exterior would lead to a future breach of the line.

The damaged external surface of the GRP pipe

If this happened, they would then be faced with the inconvenient and costly exercise of again excavating the reburied line to fix the problem. Should any future leak prove to be too challenging repair, an even more costly pipe replacement might be required.

Keen to avoid that fate, the refinery decided to seek a method to repair the external damage whilst the pipe remained excavated and accessible. This would strengthen the line and restore its integrity.

Superfast Steel was pushed onto the pipe, filling imperfections in the line

Sylmasta supply several products for damage repair. For this particular application, Superfast Steel Epoxy Putty was deemed the best solution due to the relatively small areas requiring repair, and the speed and ease with which it can be worked.

Superfast Steel comes in pre-formatted 114g stick. Multiple sticks were used for the repair. Chunks of putty were cut from the stick and kneaded by hand.

Once the putty had turned to a uniform colour and whilst remaining soft, it was pushed down onto the pipe and smoothed over the scored areas.

The putty cured to a material hard as steel over the weakened parts of the pipe

Within 10 minutes of mixing beginning, the putty began to harden. Once fully cured, it permanently imbedded into imperfections in the line.

In effect, the putty created a new layer as hard as steel over the weakened parts of the GRP pipe. The entire repair took less than two hours to complete.

Had the area of damage been larger and deeper, Industrial Metal Epoxy Paste would have been recommended.

Industrial Metal is trowel applied and with a longer work time, allowing more to be mixed and spread over significant sections of weakened pipes requiring rebuild.

The GRP line could have been further reinforced using a SylWrap HD Pipe Repair Bandage. However, the trench dug as part of the construction work was not deep enough to effectively wrap a bandage around the bottom of the pipe.

Not wanting to excavate further down, the refinery decided to rely on Superfast Steel to strengthen the line. Several years later and the underground line had still not been breached. Superfast Steel had done its job.

Case Study: Leaking Hydrogen Line Pipe Repair at Power Station in Puerto Rico

A hydrogen line at a power station in Puerto Rico undergoes leak repair and reinforcement after it was discovered to be leaking

Helping hand with hydrogen – The leaking hydrogen pipe repair that put a power station cooling system into service

Case Study Details

The power plant had previously stored hydrogen used for cooling in an off-site tank. Procuring hydrogen, refilling the tank and then keeping vast amounts of gas was an expensive process.

It was also inefficient. It could take up to four days to deliver refills to the tank, sometimes causing interruptions to power output as turbines at the plant had to be shut down when hydrogen supply ran out.

To overcome this, the plant took the decision to install a new cooling system, including an on-site hydrogen generator capable of supplying gas as and when it was needed.

Pipes would carry hydrogen from the generator to the areas of the plant it was required for cooling purposes, eliminating the need for the plant to buy and then store gas away from the site.

Because gaseous hydrogen consists of such a small molecule, very small leaks are common. These tend not to be dangerous as the tiny amounts of hydrogen being released are not enough to cause a flammable mixture in the air. Problems arise only when the gas can accumulate in a confined area.

Human senses cannot detect small hydrogen leaks as the gas is colourless, odourless and tasteless. To ensure that the newly installed cooling system was in good working order before it was put into full service, the plant therefore used portable hydrogen detectors to analyse the pipes.

It was discovered that a section of the line was leaking, suspected to be from two joints between two valves around 600mm apart. Although the hydrogen leaks posed little threat, the plant decided to repair and reinforce the pipe for efficiency reasons as well as their own peace of mind.

The line was isolated and Superfast Steel Epoxy Putty Stick applied to the joints at either end of the pipe. The required amount of Superfast Steel was cut from the stick and kneaded by hand.

Whilst soft, it was pushed tightly onto the pipe around both joints. Within 10 minutes, the putty hardened to form a steel-like material to plug any gaps in the pipe through which hydrogen could be leaking.

The line was then further reinforced with a SylWrap HD Pipe Repair Bandage applied along the entire 600mm section. SylWrap HD is a composite repair wrap with a water-activated resin which sets in minutes, curing to form an impact resistant sleeve around pipes and structures.

Despite the pipe being positioned close to a wall, the maintenance team at the plant were able to wrap the pipe effectively with a 50 percent overlay.

The Bandage was smoothed with water as the application continued. Once set, it provided a rock-hard, chemically inert outer shell over the leaking joints strong enough to prevent further hydrogen molecules escaping.

24 hours after the repair and the hydrogen pipe was repressurised. With the hydrogen detector now finding no gas in the air, the application had been a success and the new cooling system could be put into full service.

Case Study Details

The classic car had developed a rust hole. Corrosion had eaten away at a section of the inside car door where the window mechanism was anchored, causing it to fail.

As a DIY enthusiast, the car owner wanted to find a quick, cost-effective and easy method to permanently fix the rust hole. The owner required a lightweight, metal filler material which would offer resistance to water, temperature extremes and future corrosion.

Heavy corrosion had caused significant rusting to the inside door of the car

They decided to use Superfast Steel Epoxy Putty Stick for the application. Superfast Steel sets in under 10 minutes and makes permanent repairs to damage in steel, iron and other ferrous metals.

Before the repair began, the metalwork was cleaned and prepared as best as it could be. Dirt, grime, and rust were removed. Moisture repellant spray was used to drive moisture and grease out from the crack and leave a fine lubricating film to protect against corrosion.

The area was cleaned prior to repair

Once preparation was completed, the required amount of Superfast Steel Epoxy Putty was cut from the 114g stick and kneaded by hand. Whilst soft, the putty was pushed into the hole in the metalwork, where it was shaped and moulded around the screw.

Within 10 minutes, the putty had begun to harden into a material sharing the look and feel of steel. Maximum properties were reached after an hour, leaving the hole filled and the damage caused by corrosion repaired.

Case Study: Repair of a Leaking 150mm Steel 90 Degree Elbow Bend at a Quarry Wash Plant

A 150mm steel pipe elbow bend leaking at a quarry wash plant undergoes repair with a SylWrap Standard Pipe Repair Kit

When clamps don’t work – the repair of a 90 degree pipe elbow bend at a quarry wash plant

When a quarry in the UK was unable to repair a leaking 150mm steel pipe in their wash plant using a clamp due to the pinhole being located on a 90 degree elbow bend, they instead turned to Sylmasta for an alternative, versatile solution.

Case Study Details

The 150mm steel pipe was located in the wash plant of the quarry, passing across a lake. Wear and tear had caused a pinhole leak to appear in the line around 50mm away from a 90 degree elbow bend, leading foul water to escape into the lake below.

Normally when pipework failed on site, the quarry would fit a pipe repair clamp over the problem area. This was not possible in this case because of the location of the leak area being so close to the elbow.

Seeking a more versatile repair method capable of being effective on the bend, the quarry contacted Sylmasta. Once it was established that pressure could be easily shut off, a SylWrap Standard Pipe Repair Kit was delivered to the site.

The pipe was cleaned as best it could be before the repair began. Superfast Steel Epoxy Putty Stick was used to seal the pinhole. The required amount of putty was cut from the stick and kneaded by hand.

After around two minutes of mixing and whilst still soft, the putty was pushed into the hole in the pipe. Within 10 minutes it had hardened, forming a material as hard as steel which now filled the pinhole.

To further reinforce the repair, a SylWrap HD Pipe Repair Bandage was applied around the leaking section. SylWrap HD is a composite repair wrap with a water activated resin which sets rock hard in minutes.

SylWrap was wrapped and smoothed around the pipe, curing to form an impact resistant sleeve. This would help protect the pipe from future breakages, a common occurrence due to the abrasive nature of operations at the quarry.

The entire application was completed in under 30 minutes by a member of the operations team at the quarry. No training was required; they simply followed the instructions provided with the Kit to make a permanent pipe elbow bend repair.

Since the repair, the quarry group have taken further stock of SylWrap Pipe Kits, knowing them to be capable of making more versatile repairs than heavy, bulky pipe repair clamps.

Case Study Details

The 70mm malleable iron pipe connected a property with the public supply network. When the property owner was alerted to a potential leak, excavation revealed that an awkward-shaped large crack and several smaller holes had developed, through which water was now escaping.

Because the pipe was 90 years old, replacement fittings of the correct size and type were no longer manufactured. The crack and holes therefore had to either be repaired, or the entire section would need to be dug out and replaced with a new line at considerable expense.

Sylmasta recommended a SylWrap Standard Pipe Repair Kit for the application. All products in the Standard Kit have WRAS approval, meaning they are certified as safe to use for the repair and maintenance of pipes carrying drinking water.

Pressure was turned off and the malleable iron pipe cleaned and dried as best it could be prior to the two-stage repair.

Holes in the pipe included a large, awkward shaped crack

First, Superfast Steel Epoxy Putty Stick was used to seal the pipe. Superfast Steel is a fast working putty in an easy-to-use stick format which makes permanent repairs to steel, iron and other ferrous metals.

For the smaller holes, the required amount of epoxy was cut from the stick and kneaded by hand. It was pushed into all visible holes in the pipe, where it hardened within five minutes to plug all leaks.

To seal the large crack, Superfast Steel was formed into a disc bigger than the area of the pipe the crack covered. This guaranteed that no part would be missed when sealing.

This disc was then stretched over the entire crack area. Once in position, the edges of the disc were pushed tightly down onto the pipe, forming a good seal with the surface.

Once the putty had become firmer but not completely cured, the entire repaired section was tightly wrapped with a SylWrap HD Pipe Repair Bandage to compress the putty into any remaining gaps.

SylWrap HD is a composite repair wrap with a water activated resin which sets rock hard in minutes, providing an impact resistant protective layer around the pipe.

Once the application was completed, pressure was turned back on. The pipe had ceased leaking and could therefore be re-buried. The repair had cost less than £25 to complete, including delivery of the SylWrap Kit and the property owner described it as going “fantastically well.”

Case Study Details

Heavy corrosion had caused numerous cracks to appear on the 900mm steel pipe around a stub flange. The leak point was located in an underground chamber, which had subsequently filled with water escaping the pipe at high pressure.

Accessing the pipe was difficult even before the flooding of the chamber. A repair clamp could not be fitted because of the flange, and the main was so close to the ground that there was insufficient room for pipe repair tapes or bandages to be wrapped around the pipe.

There was no visible means of isolating the main either, meaning that pressure could not be turned off or reduced. Replacing the damaged section would have involved excavating the chamber and shutting down the main for a prolonged period, something not considered an option by the water company operating the system.

As water was removed from the chamber, the scale of the leaks on the main became evident

As a result, repairing the main had been considered impossible. It had been allowed to leak unabated since the problem was discovered, save for a few cursory checks and the pumping out of water when flood levels became dangerously high.

That was until an engineering team arrived on site, accompanied by a technician from Sylmasta, who were determined to formulate either a method for repairing the main or a means of substantially reducing the amount of water being lost.

Before any repair could be attempted, water had to be pumped out of the chamber. Once this had been done, an engineer accessed the pipe and hammered a series of plastic plugs into the larger cracks along the flange.

An engineer hammered plastic plugs into the significant cracks, reducing the amount of water being lost so that an inspection could take place

The plugs reduced the amount of water escaping from the pipe enough for a proper inspection to take place. The engineer in the chamber then spotted a stopcock a little further along the pipe.

They were able to reach the stopcock, preventing flow into the leak area. With pressure now turned off, it meant that Superfast Steel Epoxy Putty could be used to attempt to permanently seal the cracks in the main.

Numerous Superfast Steel Epoxy Sticks were used for the repair

Superfast Steel has a fast, 10 minute work time and comes in an easy-to-use 114g stick format. A large number of sticks had to be used in the application because of the size of the repair.

Each stick was kneaded by hand. Whilst soft, the putty was pushed into visible holes in the pipe where it hardened, filling the crack. Superfast Steel was also used to seal the flange and as a means of permanently fixing the rubber plugs in place.

Superfast Steel plugged the visible cracks in the pipe and permanently fixed the rubber plugs in place

Because of the diameter of the pipe and the size of the damage area, it took over an hour to apply the necessary Superfast Steel. With flow isolated, it was difficult to tell whether all the leaks in the pipe had been found and sealed.

Even after pressure was restored, it was still hard to identify remaining problem areas. As a result, the maintenance team decided to return 24 hours later to check the effectiveness of the repair.

With the main continuing to leak the following day, further Superfast Steel was used to plug remaining cracks and a valve fitted

Unfortunately, this inspection revealed that the main was again leaking, although nowhere near as seriously as before. There were several small leak areas which had not been suitably arrested the previous day, alongside a larger jet of water escaping from a gap between the flange and the pipe.

Further Superfast Steel was used to seal the smaller leak areas. The epoxy putty was worked into a sausage shape and pushed into the remaining cracks in the pipe.

With most of the leaks arrested, the valve funnelled any water still attempting to escape into one area

For the larger leak, the engineering team manager hit upon the idea of fixing a valve in place using more Superfast Steel. The water trying to escape the main would be channelled towards this valve. A tap would be fitted and closed, sealing the pipe shut.

A tap was then fitted, shutting off the valve

Tapping off the main ended up being a success, much to the delight of the water company and the engineering team. Normally, Sylmasta would recommended reinforcing the epoxy putty with SylWrap HD Pipe Repair Bandage, but that was just not possible in this application.

It may have taken two days, but the ‘impossible’ water main repair had been completed, reducing the levels of water being lost and preventing any further flooding of the chamber.

Case Study: Magic Corner Kitchen Unit Repair Saves a Client Over £200 in Replacement Costs

A magic corner kitchen unit undergoes repair using Superfast Steel Epoxy Putty after a pin snapped off

Magic repair of a magic corner – Superfast Steel prevents a broken kitchen unit needing a £290 replacement

When a magic corner unit in a Sylmasta client’s kitchen collapsed, they were left facing the prospect of paying £290 for a replacement – until it was decided to attempt a repair using the high-strength bonding properties of Superfast Steel Epoxy Putty.

Case Study Details

A magic corner kitchen unit makes use of dead space in corner cupboards which are otherwise hard to access. A slide out mechanism attached to a cabinet door allows items to be easily stored and retrieved from blind corners.

There are several reasons why magic corners can break. Wear and tear is one. Frequent opening and closing of the cupboard and stress on the sliding mechanism will take its toll after many years.

Magic corners will often be overloaded in excess of the weight that the manufacturer recommends they carry. Because they are attached to a cupboard door rather than being a part of the actual unit, overloading can lead to units collapsing and subsequent damage to the door itself.

In this case, the magic corner unit was very old. The client also admitted that they may have overloaded it. Eventually, this led to the magic corner collapsing, detaching it from the kitchen cupboard door.

Upon inspecting the broken corner, the problem was discovered to have been caused by a vital pin on which the mechanism pivoted, breaking away from the frame and causing the detachment.

A replacement magic corner would have cost £290 and required some advanced DIY skills to fit. After consulting Sylmasta to see if a repair was possible, it was decided to attempt to fix the magic corner kitchen unit using Superfast Steel Epoxy Putty.

Superfast Steel is used for filling holes and cracks, restoring surface profile, fabricating new parts and for high-strength bonding between materials. For this particular application, it was Superfast Steel’s adhesive properties that were required.

To use Superfast Steel, the required amount is cut from the 114g stick and kneaded by hand. This causes a chemical reaction to take place between the resin and hardener contained within the stick, and within 10 minute the soft material will have cured into one as hard as steel.

The damaged pin was around 100mm in length and had been welded to the magic corner prior to the collapse. The pin was to be reattached to the unit using Superfast Steel, which would provide a bond as strong as the previous welding.

Completing the reattachment took less than 30 minutes. Within an hour, the putty had fully hardened. The magic corner could be filled with kitchen items again – although the client was careful not to overload it this time.

One Superfast Steel Stick was all that was required for the application . At an outlay of only £10.08 plus postage, the repair represented a huge saving compared to the cost of replacing the magic corner.

Case Study Details

Arthur J. Poole manufactured a huge range of candle-lit lanterns, lanterns for police offices, lamps for use on the railways, maritime signal lamps capable of transmitting Morse code, and copper coal buckets from his factory in the heart of Birmingham during the 19th century.

The lantern in question was candle powered, dating it to the 1870s or 1880s before paraffin became more widely used. For an item the best part of 120 years old and which had clearly spent most of its life as a working lantern, it was in remarkably good condition.

There were two areas which needed attention before it could be used once again. The lantern no longer had a latch to close the door in place. Whenever there was a breeze or the device was being transported by its handle, the door would therefore swing open and the candle inside would be extinguished.

Original fitting for holding a candle in place. A new part needed to be made to hold larger, modern day candles

The other problem was that the original candleholder was very small, and not suited to most modern day candles. To overcome this, it was decided to make a round platform that could take tea lights or other larger candles and fix a spike on the bottom that could slot into the existing candleholder.

This was done using Superfast Steel Epoxy Putty. Superfast Steel comes in a pre-formatted 114g stick. The user cuts off the amount of putty required and then mixes it by hand, instigating a chemical reaction between the resin and hardener.

Superfast Steel has a work time of between 5-10 minutes. Whilst soft, it can be shaped and formed as desired. Once cured, it offers super-strength adhesion between different materials and forms a material as hard as steel.

To create a new candleholder, Superfast Steel was moulded into the required shape to make the platform. Once the platform had cured, the spike was shaped and added. Whilst soft, the spike was pushed into the existing fitting to ensure it was a perfect fit.

The spike easily bonded to the platform, creating a new holder capable of supporting a modern candle inside the lantern and completing part one of the restoration.

The new candleholder enabled the lantern to hold a modern candle in place

To create a new handle for the door, a metal wire was bent into a T-shape by folding a strip in half, then bending the two ends at right angles. It was attached to the door via two plastic tubes which were bonded to the lantern using further Superfast Steel.

When the door was closed, this metal wire could now drop into an existing latch attached to the opposite side of the lantern, locking it in place and preventing the candle from blowing out.

A coating of black paint was added to the wire, the plastic tubing and the Superfast Steel to complete the restoration at a cost of under £15.

The lantern is now lighting up a garden in East Sussex and ready for another 120 years of service. Arthur J. Poole himself would have been impressed.
