Video: How to increase live leak pipe repair pressure resistance using SylPad

SylPad Pressure Resistance Multiplier is used alongside Wrap & Seal to increase the pressure resistance of a live leak pipe repair

This demonstration video was filmed at Sylmasta HQ to show how SylPad can increase the pressure resistance of Wrap & Seal Pipe Burst Tape by up to three times when making a live leak repair on pipework in excess of 150mm diameter.

About this Pipe Repair Video

SylPad is used for repairing holes on pipework over 150mm diameter. It works by better concentrating the elastic force of Wrap & Seal directly over the hole in the pipe, increasing pressure resistance by up to three times.

This demonstration video was filmed at Sylmasta HQ. A 7.2mm hole was cut into a 450mm steel pipe with operating pressure set at 3 bar. Such a repair without SylPad would normally require four Large Wrap & Seal (PB-50x4HD) to seal the leak.

The repair began by drawing a line on the pipe to mark where the hole was. This meant the exact location of the leak could be identified once the tape was wrapped around the pipe.

Wrap & Seal was anchored around 50mm to the side of the leak. The tape was then wrapped towards the hole with a 50 percent overlay. Once the hole was reached, the application continued directly over it.

After two layers of Wrap & Seal were built, SylPad was pushed onto the tape directly above the hole as marked by the pen. SylPad stuck without the need for any adhesive.

Wrap & Seal was then wrapped over SylPad, securing it in place and forming a ridge over the hole. Greater pressure was now being directed down onto the hole rather than spread outwards, as would be the case had SylPad not been used.

By the complete application of only one PB50x4HD tape, the leak was successfully sealed. SylPad had reduced the number of Wrap & Seal required from four to one, speeding up the repair significantly.

To further showcase the increase in live leak pipe repair pressure resistance possible using SylPad, a second tape was added and pressure through the demo rig pushed to 6 bar.

A third Wrap & Seal then achieved 9 bar pressure; resistance which would have needed 12 x PB50x4HD tapes without the use of SylPad.

SylPad is available to be as an individual product. It is also included in is as standard in SylWrap Universal Pipe Repair Kits 633 and 866 and all SylWrap Pipe Repair Contractor Cases covering pipework 150mm upwards.

Because SylPad is contained within layers of Wrap & Seal and does not come into contact with pipe contents, it does not require WRAS approval for use in high pressure live leak pipe repair on supply lines carrying potable water.

Case Study: Corroded 30-Metre Section of Sewer Force Main In Underground Vault Repair

A severely corroded sewer force main pipe in Hawaii undergoes repair and refurbishment using the Sylmasta Pipe Refurbishment System

Say aloha to a sewer force main in Hawaii restored from a corroded state by a repair made using the Sylmasta Pipe Refurbishment System

An engineering company in Hawaii refurbish a severely corroded 30-metre section of 450mm ductile iron sewer force main inside an underground vault, rectifying a previous repair attempt which ended up sandblasting a 75mm round hole in the pipe.

Case Study Details

The 450mm ductile iron pipe inside the vault was the final section of the sewer force main before it discharged into a manhole housing a gravity collection system. Its operating pressure was around 3 bar.

It was installed in the 1970s. Conditions inside the often-flooded vault over a period of nearly 50 years had led to severe exterior corrosion and a significantly weakened pipe.

Water was pumped out of the flooded vault before repair

A recent attempt to add structural strength and protect against further corrosion involved sandblasting the line prior to coating with epoxy. Unfortunately, the contractor failed to realise just how weakened the ductile iron had become.

Sandblasting to clean the pipe subsequently put a 75mm round hole in the top of the sewer between a flange and the concrete wall where the main entered the adjacent manhole. Wastewater could escape through this hole when the line was pressurised.

To seal the leak in the pipe, the contractors ordered a pipe repair clamp specifically fabricated for the line. But because the surface was so badly deformed by corrosion, it was impossible for the clamp to achieve a watertight seal. There were also concerns that tightening the clamp fully would further breach the brittle metalwork.

The pipe surface was severely corroded, leaving it weakened and brittle

The contractors contacted Sylmasta for assistance with the corroded sewer main repair. They needed to improve the surface profile of the pipe to make the clamp effective, before refurbishing the entire 30-metre section inside the vault to keep the line operational and protect against further degrading.

Any repair method had to take into account the weakness of the line and the damage already done by sandblasting. Sylmasta therefore recommended using Stages 2, 3 and 4 of their Pipe Refurbishment System.

The hole was attended to first. Wire mesh was used to bridge the gap. Industrial Metal Epoxy Paste was then applied around the entire diameter of the pipe between the flange and the wall, including over the hole. The wire mesh prevented any epoxy paste entering the pipe.

Sandblasting to clean the pipe during a previous repair attempt left a hole in the pipe, through which water could escape when the sewer main was pressurised

Industrial Metal is a two-part epoxy paste used to rebuild weakened metalwork and improve surface condition of pipes. In this application, 5kg of Industrial Metal filled in all imperfections caused by pitting and increased pipe thickness surrounding the hole.

Once cured, Industrial Metal sealed the hole and rebuilt the pipe, leaving it strong enough to withstand the clamp being fitted and smooth enough to ensure a watertight seal could now be achieved.

Industrial Metal could have held the leak of its own accord. The contractors though decided to take a belt and braces approach by also fitting the clamp, seeing as it had been specifically made for this sewer line.

Attention next turned to refurbishing the rest of the corroded sewer main. Loose material was carefully cleaned off using wire brushes before the sewer main was painted with Liquid Metal Epoxy Coating.

10kg of Liquid Metal was used to apply two coatings across the entire 30-metre pipe, the two flanges at either end and the coupling in the middle. Re-coat time was four hours, meaning the application of Liquid Metal took one day.

Liquid Metal cured to create a new, metallic, hard-wearing pipe exterior for the sewer main, providing a shield against corrosion and a waterproof barrier against future leaks.

The final stage of the repair saw the sewer main given further reinforcement using 20 x SYL866HD SylWrap Pipe Repair Bandage. SylWrap Bandage is a composite repair wrap with a water-activated resin.

It was wrapped and smoothed around the whole pipe, curing within minutes to form a rock-hard, impact resistant layer of further protection. Six layers of SylWrap Bandage were used based on the 3 bar operating pressure of the sewer main.

The repair was completed by wrapping the entire 30-metre pipe with SylWrap Bandage for a rock-hard, reinforced final layer of protection

From sealing the hole to reinforcement with SylWrap Bandage, the repair was completed over the course of one week. The contractors were impressed with how easy all three Sylmasta products were to apply given the cramped, wet and dirty conditions inside the vault.

They had originally planned to encase the sewer main in concrete after refurbishment as an additional means of protection. This was no longer deemed necessary once they saw the strength and effectiveness of the repair.

At a total cost of just under $5000 including delivery to Hawaii, refurbishing the corroded sewer force main provided a significant financial saving compared to ripping out the pipe and replacing it.

Case Study Details

Sylmasta offices received an early morning phone call from a panicked maintenance manager of a nursing home in the south of England. A 150mm metal pipe in the heating system running through loft space had developed a pinhole leak.

A constant, steady drip of water was escaping the pipe and saturating the surrounding loft space. Shutting off the pipe to stop the leak whilst waiting for a plumber or heating engineer to make a repair or replacement would have left the nursing home without heating. This was not an option with winter approaching.

The nursing home therefore needed to make a live leak repair that same day to ensure residents were kept warm and prevent significant water damage in the loft space.

Immediately after the phone call, the maintenance manager drove 20 miles to Sylmasta HQ in Sussex to collect a SYL-616-UP SylWrap Universal Pipe Repair Kit. A Universal Pipe Repair Kit seals leaking pipes even when pressure cannot be turned off by following a simple two-stage process.

Wrap & Seal Pipe Burst Tape was used to repair the pinhole leak. Wrap & Seal is a self amalgamating waterproof tape which stretches by three times its length. As it is wrapped and applied around a pipe, it fuses to form a solid rubber band containing pressurised live leaks.

One 25mm x 2m Wrap & Seal was applied to the heating pipe, easily withstanding the pressure the pipe was operating at to seal the leak. The second stage of the repair involved overwrapping the tape with a SylWrap HD Pipe Repair Bandage.

SylWrap HD is a composite wrap with a water activated resin which sets rock hard in minutes. It was wrapped and smoothed around the pipe, curing to form an impact resistant protective shell reinforcing the Wrap & Seal for a permanent repair.

It took the maintenance manager under 30 minutes to repair the leaking pipe once they arrived back at the nursing home, leaving residents none the wiser there was a problem with the heating system.

Not only did a SylWrap Pipe Repair Kit ensure there was no impact to residents, but it cost less than £80 – representing a significant saving compared with an emergency callout for a plumber at a time when many nursing homes in the UK are in deep financial trouble.

Case Study Details

The Christmas light projector projected festive scenes of joy and happiness onto the outside wall of a house in the United Kingdom via a relatively simple setup.

A spike was stuck into the ground where the projector was to be positioned. The projector then slid into the spike and was fixed in place by a fitting.

One day, the family returned home to find the projector detached from the spike and the fitting had snapped into two pieces. The family believed there were two possible causes; either accidental damage or one of the neighbouring allotment holders channelling their inner Ebenezer Scrooge.

The Christmas light projector fitting had been broken into two pieces

Whether accident or deliberate sabotage, no decorative light show meant Christmas would have to be cancelled with much wailing and gnashing of teeth – unless the fitting could be repaired.

Thankfully, no wise men nor Christmas miracle were needed. Just Superfast Aluminium Epoxy Putty Stick to permanently bond the fitting back to together.

Superfast Aluminium is a fast-working epoxy putty. Although it is formulated for the repair of aluminium, other alloys and metals, it can also bond to many plastics. It was shaped in this application to hold the parts together mechanically.

Enough putty was cut from the stick and kneaded by hand until it turned a uniform silver colour. Whilst soft, it was used to reassemble the pieces of the fitting.

A ring of Superfast Aluminium was applied around the break area after reassembley for added reinforcement

Within 10 minutes, Superfast Aluminium had hardened to form a cohesive bond holding the fitting back together. More epoxy putty was then mixed and applied as a ring around the entire break area, reinforcing the repair and giving it added strength. Just in case Scrooge returned.

Case Study Details

The narrowboat had a raw water system for cooling the engine, including a manifold mounted heat exchanger. It worked by pumping canal water into a tank containing a series of pipes on the exhaust manifold.

Inside these pipes ran engine coolant, circulated around the engine block by another pump. The canal water in the tank passed over the pipes, cooling the engine coolant in the same way a fan does in a car. The water was then expelled through the exhaust.

The narrowboat was moored on a canal in Hertfordshire, around 30 miles north of London, when the owner discovered a 15mm x 15mm hole had appeared in the heat exchanger manifold.

A 15mm x 15mm appeared in the engine heat exchanger manifold

They decided to repair the manifold using Superfast Titanium Epoxy Putty Stick. Superfast Titanium was selected because of its high temperature resistance, enabling it to withstand up to 280°C.

Within 24 hours of the narrowboat owner contacting Sylmasta, Superfast Titanium had been delivered to a collection point close to where the vessel was moored.

Before the repair, the narrowboat owner cleaned and rubbed down the heat exchanger manifold to improve adhesion with the epoxy putty. Aluminium mesh was placed over the hole as a precautionary measure to prevent any epoxy putty entering the manifold exchanger.

Enough Superfast Titanium to cover the hole was then cut from the stick and kneaded by hand until it turned a uniform, golden brown colour to indicate successful mixing.

The putty was applied over the mesh and surrounding area. It was pushed firmly onto the manifold to ensure maximum contact before being smoothed off with a little water.

Case Study Details

The pump housing was part of a system which extracted water from a nearby river and transported it around the copper mine, where it was then used in a number of different processes.

Sand, silt, dirt, stones and other debris were all present in the water as it passed through the pump housing. Following years of exposure to the river water, the housing was now suffering from severe corrosion, abrasion and wear damage.

As it appeared the pump housing was beyond repair, the mine sought quotes for fabrication and installation of a replacement part from several companies. When these were deemed too expensive, it was decided to attempt refurbishment.

The pumping house was heavily damaged after years of extracting water from a river

The mine contacted Sylmasta’s approved supplier in Bulgaria. The supplier had recently spent several days completing a comprehensive product training programme at Sylmasta HQ in the United Kingdom, including a module on restoring damaged metalwork.

They recommended using Ceramic Brushable Epoxy Coating and WearShield Epoxy Paste in conjunction to both repair the existing damage and protect the pump housing from further deterioration.

Ceramic Brushable is a ceramic-filled epoxy coating reinforced with silicon carbide. It seals and protects parts, machinery and surfaces by forming an ultra-smooth, hardened layer of protection.

WearShield is an epoxy paste heavily filled with alumina beads and a high resin content. The dense alumina structure of the cured material enables it to offer the ultimate resistance against all types of impact in the most abrasive environments.

The pump housing was thoroughly cleaned before the repair took place

The pump housing was taken apart and thoroughly cleaned to remove as much rust, dirt and grime as possible. An initial coating of Ceramic Brushable Blue was painted all over the metalwork using a brush, sealing the original surface.

Ceramic Brushable Blue was applied to the pump housing followed by a thick layer of WearShield. The alumina beads are visible in the material

Once Ceramic Brushable had cured, WearShield was applied on top with a spreader. The composition of WearShield makes it easy to build significant, dense layers of protection quickly. In this case, WearShield cured to form a 30mm thick alumina-reinforced shell over the pump housing.

Ceramic Brushable Epoxy Coating provides an ultra-smooth, low-friction finish during pump housing repair in Bulgaria
A top coating of Ceramic Brushable left an ultra-smooth, low-friction finish to complete the repair

Because the alumina beads make cured WearShield a slightly rough material, it was decided to topcoat with more Ceramic Brushable. The ultra-smooth, low-friction finish provided by Ceramic Brushable would improve flow through the pump housing, making it more efficient once it went back into service.

Completing the repair took just two days and saved the mine a substantial amount of money, The pump housing will remain in service for many more years thanks to the significant protection provided by WearShield and Ceramic Brushable.

Case Study Details

A valley in Scotland at the confluence of three rivers had been flooding for over a century, affecting homes and business in three towns and the railway line connecting them.

With climate change making flooding a more regular occurrence, a multimillion pound flood defence project was commissioned. This involved the construction of a large earth storage dam and concrete flood defence walls.

The state-of-the-art dam was designed to retain water from the rivers when levels were high, reducing the risk of flooding in the towns downstream whilst leaving flow unaffected at other times.

Alongside the dam, flood defence walls were built to protect the railway line and the residential estates closest to the river which had suffered the most from water damage over the past 25 years.

Not long after the project finished and one section of the defence walls began leaking. It was made up of concrete slabs sealed together by a grout compound. This compound was now being washed out by floodwater, causing large gaps to appear between the slabs.

A civil engineering company were called in to inspect the problem and formulate a repair. After consultation with Sylmasta, it was decided the gaps in the flood defence wall should undergo repair using AB Original Epoxy Putty.

AB Original is a ceramic-filled, high-strength epoxy putty with an extended work time and excellent underwater and wet surface adhesion.

The engineering company were confident in the suitability of AB Original having seen a previous case study where the Environment Agency sealed a large crack in a wall between a river and a trout farm.

The original sealing compound between concrete slabs had washed away, with the subsequent gaps packed with AB Original

45kg of AB Original Epoxy Putty were delivered to site in 200g sticks. Supplying the putty in sticks formatted to the correct mix ratio removed the need to measure out separate components of resin and hardener from tubs, speeding up the repair.

Each stick was mixed by hand until it turned a uniform colour. Whilst still soft, the putty was pushed into the gaps between slabs. The two-hour work time of AB Original meant the engineers making the repair could take their time mixing and carefully applying the putty without the threat of premature curing.

Once cured, AB Original formed a rock-hard material and a watertight seal much more effective than the original grout compound. With its wet surface properties, the putty easily bonded to the saturated concrete.

Gaps in the concrete flooring were also sealed thanks to the underwater curing properties of AB Original

Gaps had also appeared between slabs making up a floor, which was now underwater because of the flooding. AB Original cured below the water line, sealing the floor in the same manner as the wall.

Such a straightforward repair ensured the construction of the flood defence wall being completed with an ineffective sealing compound did not cause long-term issues.

AB Original allowed the problem to be remedied quickly and easily, avoiding a costly rebuild or significant reinforcement of the structure within only a few years of completion of the project.

The putty is now playing a small part in protecting homes, businesses and transport infrastructure in the valley against flooding.

Video: How to make an online pipe repair without using tapes, wraps or a clamp

Online pipe repair made using epoxy putty and a pipe fitting rather than any tape, wrap or clamp

This video was filmed on a 150mm steel pipe test rig at Sylmasta HQ to demonstrate an online repair method using no tapes or clamps initially developed for a major project in Malaysia sealing live leaks on pipelines which could not be wrapped.

About this Pipe Repair Video

A large hole was cut into the 150mm steel pipe close to a flange joint, meaning the test rig could not be repaired with Wrap & Seal Pipe Burst Tape, SylWrap Pipe Repair Bandage or any type of clamp. Pressure was set at 5 bar.

To seal the leak, a plastic PVC fitting was cut to shape and then bonded to the pipe using Superfast Aqua PW Epoxy Putty. Superfast Aqua PW has a fast five-minute work time and offers excellent wet surface adhesion, enabling it to permanently bond with the pipe despite it being saturated by the continued escape of water.

Three 114g Superfast Aqua PW Sticks were used to ensure a high-strength repair and a watertight seal between the fitting and the leak. Heat was used to accelerate the cure of the epoxy putty so that it fully hardened within a few minutes; otherwise, it would have needed to be left overnight for up to eight hours to achieve working strength.

Once fully cured, Superfast Aqua PW channelled the leak path through the fitting. An end cap and valve was then screwed on, containing pipe content and stopping the leak.

In this demonstration, the screwing of the cap resulted in a pinhole leak appearing where a weakness in the putty repair existed. This often happens and is easily dealt with by applying more Superfast Aqua PW around any pinhole or other leak areas which appear.

Pressure on the repair was relieved by unscrewing the cap. Another 114g stick of Superfast Aqua PW was then applied to seal the newly identified pinhole. When the cap and valve were screwed back on, the leak was fully arrested.

To demonstrate the strength and resilience of the repair, the cured epoxy putty was then attacked with a hammer after the demonstration had been completed.

Superfast Aqua PW has WRAS approval, meaning it is certified to British standards as safe to use on pipes and fittings carrying drinking water. It will bond to steel, iron, copper, PVC plastic, GRP, ceramic and concrete for effective online pipe repair where wrapping or clamping is not possible.

Video: How to use a Sylmasta AB Original Epoxy Putty Stick to repair areas of damage

Sylmasta AB Original Epoxy Putty Stick used to repair deep holes in a wooden demo piece

This repair video shows how easy it is to use a Sylmasta AB Original Epoxy Putty Stick, followed by the mixed putty being applied to a wooden demonstration piece where it filled a missing corner and deep holes before being sanded to a smooth finish.

About this Epoxy Putty Repair Video

Sylmasta AB Original Epoxy Putty has a wide range of uses in pipe repair, refurbishment and maintenance applications. It is made by Sylmasta at their UK site using the latest in epoxy stick manufacturing technology.

Each 200g stick and contains resin on the outside and hardener in the middle. Combining the two removes the need to measure out resin and hardener from separate components.

Instead, the user simply cuts off the required amount of putty from the stick and kneads it by hand for around five minutes, until the material is a uniform colour and streak free.

AB Original comes with an extended two-hour work time. It enables more material to be mixed and longer taken when shaping and applying compared to fast working epoxy putties which cure off in minutes.

It comes in white, grey and black and bonds to metal, wood, brick, masonry, concrete, porcelain, ceramics, clay and most plastics. AB Original even cures underwater and has high wet surface adhesion.

Because of its versatility, AB Original is used in a variety of different applications. These include sealing leaking pipes, filling holes and cracks, rebuilding small areas of damage and high-strength bonding between parts.

Once cured, AB Original can be tapped, drilled, screwed, sawed, machined, ground, filed, or painted.

This demonstration video was filmed at Sylmasta HQ and shows AB Original Epoxy Putty being used to repair wood. A corner was cut away and three large, deep holes drilled into a wooden demo piece.

The corner was rebuilt with AB Original and each of the holes filled with a different colour of the epoxy putty. Water was used to show the ultra smooth finish AB Original achieves, followed by the cured material being sanded.

AB Original can be used to make repairs in interior and exterior settings. It achieves a full cure in 24 hours and is resistant to water, chemicals, and temperature extremes. It also insulates parts and can be used as a sacrificial layer against corrosion and chemical attack.

Video: How to make a high-strength metalwork repair with Industrial Metal Epoxy Paste

How to make a high-strength metal repair using Industrial Metal Epoxy Paste

This repair video shows how easy it is to mix and apply Industrial Metal Epoxy Paste to repair a significant hole in metalwork, followed by a demonstration of the machinability of the cured material and its strength.

About this Epoxy Paste Video

Industrial Metal is a metal-filled epoxy repair paste used to protect and reinforce metalwork, repair large holes and cracks and rebuild areas weakened by corrosion, chemical attack, wear and impact.

It is filled with corrosion-resistant platelets which provide excellent protection, whilst also giving Industrial Metal a smoother finish than other epoxy pastes when machined.

For this demonstration video filmed at Sylmasta HQ, a large hole was drilled into a metal demo piece. It was then repaired with Industrial Metal before being machined and undergoing strength tests.

First, the metal surface was cleaned and prepared using Sylmasta Non-Flammable Degreaser and an abrasive disc, revealing white metal.

The two parts of Industrial Metal were easily mixed and applied using a wooden stirrer. The hole was filled with Industrial Metal and the epoxy paste pushed firmly into the surface to ensure maximum contact and avoid trapping air.

A full cure was achieved in 24 hours, leaving the hole seamlessly repaired with a new metallic material. The cured Industrial Metal was then drilled and tapped, demonstrating its high machinability.

Next, a bucket was filled with 21kg of sand and suspended from the demo piece to showcase the strength and hardness of Industrial Metal.

Two grades of Industrial Metal are available. Standard comes with a 60-minute work time. It is used at higher ambient temperatures or where significant amounts of epoxy paste are being mixed at once, removing the threat of premature curing from the application process.

Industrial Metal Rapid has a five-minute work time, achieves a functional cure in 60 minutes and a full cure after 24 hours. It enables metal repair to take place more quickly than the standard grade, minimising downtime and disruption.

In pipe repair applications. Industrial Metal rebuilds and strengthens degraded pipelines by increasing outer wall thickness and fills damage caused by impact and pitting, restoring surface profile.
