Case Study Details

Luxury portable toilet trailers are mobile restroom facilities used for large outdoor occasions, such as music festivals and sporting events. They include flushing toilets, urinals, sinks with running water, mirrors and lighting, offering a much more comfortable experience than standard portable toilets.

Toilet trailers require no connection to permanent plumbing. Instead, the wastewater they produce is stored in holding tanks between the floor of the restroom and the undercarriage of the trailer. When the event has finished, the tanks are drained and the wastewater taken to a treatment site before the trailer is moved onto its next destination.

Constructing a portable toilet trailer is expensive, and so when one of the United Kingdom’s leading suppliers discovered holes starting to appear in the wastewater holding tanks of two of their units, they contacted Sylmasta for advice on whether a repair was feasible.

Damage to the underneath of the first portable toilet trailer
The second trailer was suffering from more extensive corrosion and surface damage

The plumbing, fixtures and fittings in each of the trailers were otherwise in perfect working order. The company therefore wanted to avoid decommissioning the two trailers if the holes in the wastewater tanks could be plugged and the weakened metalwork strengthened against future damage.

Sylmasta recommended a two-stage repair, starting with Sylmasta AB Original Epoxy Putty and finished with Liquid Metal Epoxy Coating. The first trailer was jacked up, enabling access underneath the wastewater holding tank. The metalwork was then ground down to remove rust, dirt and grime.

AB Original Black was supplied in stick format for the plugging of the holes. An AB Original Stick combines the resin and hardener pre-measured rather than in a tub of Part A and a tub of Part B, eliminating the need for weighing out and mixing separate components. This makes a repair quicker and easier.

The required amount of putty to fill a hole was cut from the stick and kneaded by hand. Once the putty had turned a uniform black colour but was still soft, it was pushed into the hole. After two hours, AB Original cured to form a rock-hard sealing material. Every hole in the tank was permanently filled in this way.

Once all the holes had been attended to, the entire bottom of the trailer – an area 1.3 metres by 2.5 metres – was painted with Liquid Metal Epoxy Coating. Also painted were the metallic box and pipe fitted to the bottom of the holding tank, through which wastewater was removed. Two coatings of Liquid Metal were brush applied, curing to form a smooth, metallic, hard-wearing surface.

This new surface repaired and strengthened the weakened metalwork to increase structural integrity. It acted as a protective shield against further external corrosion and encased the wastewater tank in a new outer shell, capable of containing the wastewater if the original metalwork became fully breached in future.

After the repair of the first toilet trailer was completed, the second was jacked up and fixed by following the exact same process. Each trailer could go back into service 24 hours after the second coating of Liquid Metal had been applied.

In total, 10kg of AB Original and 10kg of Liquid Metal were used to repair the two portable toilet trailers at a cost of under £800, representing a huge saving on replacing the units. The company are now planning to use the repair method on other units when they become weakened by corrosion, potentially extending the lifespan of their entire fleet by up to 10 years.

Sylmasta named Global Player Export Business of the Year

Sylmasta was named Sussex Chamber of Commerce Export Business of the Year

Increasing growth into overseas markets sees Sylmasta pick up prestigious award from Sussex Chamber of Commerce

Sylmasta have been named Global Player Export Business of the Year at the Sussex Business Awards 2023.

Held annually by the Sussex Chamber of Commerce, the Sussex Business Awards are considered amongst the most prestigious in the county with hundreds of high-performing businesses put forward.

The Global Player Award goes to a Sussex-based company that has demonstrated significant and sustained growth internationally through harnessing the opportunity of overseas markets, proving that exporting can power business growth. 

From their headquarters in West Sussex, Sylmasta manufacture industry-leading repair and maintenance products for the purpose of extending the working life of parts and equipment.

The Sylmasta Pipe Refurbishment System is at the core of the Sylmasta range, and is built around a flexible four-stage process enabling a wide variety of complex repairs to be made to pipework of all diameters and types.

Sitting alongside the Sylmasta Pipe Refurbishment System is the SylWrap range of leak repair solutions, a series of products used to permanently fix leaking pipes in under 30 minutes even when pressure cannot be turned off.

Away from pipe repair, Sylmasta manufacture additional epoxy putties, pastes and coatings which repair and protect machine parts and equipment from problems including corrosion, abrasion and impact damage.

https://twitter.com/SussexChamber/status/1672590681485836290

Whilst Sylmasta has a strong presence in the United Kingdom including working with several water companies to repair live leaks on the public supply network, exports accounted for 45 percent of the company’s business in 2022.

That figure is set to grow through new distribution in the Philippines, Indonesia and Australia over the coming months. Sylmasta have made great inroads into Latin America, building on long-established distribution in the likes of Argentina and Puerto Rico with SylWrap gaining approval for use on the public water network in Mexico.

The majority of Sylmasta products are made-to-order, enabling rapid turnaround. An epoxy wear compound manufactured in Sussex on a Monday can be in use at a mine in Chile by Friday, repairing and protecting plant equipment.

Managing director Simon Bedding collected the award on behalf of the Sylmasta team, which has grown in size by over 40 percent since 2020 thanks largely to the increased focus on the export market.

Mr Bedding said: “What an honour it was for Sylmasta to receive the Global Player award, especially when up against such strong competition. We are grateful to Sussex Chamber of Commerce for the opportunity and for putting on such a fabulous awards ceremony, we had a terrific evening.”

The award was celebrated back at Sylmasta HQ with a few bottles of English Sparkling Wine – also made in Sussex! Sylmasta will now move onto the South East Regional Business Awards, where they will be up against fellow Global Player Winners from Kent, Hampshire, Isle of Wight, Surrey and Thames Valley.

Case Study: Reassembly & Repair of Composite Stone Water Fountain Cracked into Pieces

A composite stone water fountained cracked into multiple pieces undergoes repair and reassembly

Water fountain repair cracked – putting the pieces of a favourite garden ornament back together

Case Study Details

The water fountain consisted of two tiers and was made from composite stone. When winter temperatures in Wales plummeted below -10°C, the upper bowl cracked into several pieces due to water inside it freezing.

When Spring arrived, the owner of the water fountain decided to try and repair and restore their favourite ornament. Not only did the upper bowl need to be bonded back together, but there were numerous other cracks and missing sections requiring attention.

Crack lines show the significant damage across the entire upper bowl of the fountain

Sylmasta advised that Rapid 5 Minute Epoxy Adhesive be used first to reassemble the fountain. Rapid 5 Minute creates high-strength, permanent bonds between many materials, including composite stone.

The five-minute cure meanwhile is long enough for parts to be carefully assembled and rearranged if necessary before the adhesive sets, at the same time as requiring minimal holding or clamping.

Rapid 5 Minute comes with the two components that make up an epoxy adhesive – resin and hardener – kept separate. The 25ml cartridge extrudes the parts in equal measures, after which they are mixed together for around 30 seconds with a spatula.

The fountain owner extruded the epoxy onto a piece of cardboard for mixing. The mixed adhesive was then applied using the spatula to one of the surfaces to be bonded, and the pieces pushed together and held in place.

Any overspill of epoxy was thoroughly cleaned off the stonework. Rapid 5 Minute exposed to sunlight can yellow with age, which would have looked unsightly against the pale coloured fountain.

After five minutes, the stonework no longer needed to be held together as Rapid 5 Minute had begun to set. The fountain was left undisturbed for a further 30 minutes, allowing the epoxy adhesive to reach maximum properties.

Once the upper bowl had been reassembled, any remaining cracks and missing sections were filled in using Sylmasta AB Original Epoxy Putty. AB Original is a hard wearing, waterproof, ceramic-filled putty which bonds to all materials.

It offers a two-hour work time, enabling the putty to be mixed, moulded into shape and applied without any worry about premature curing. It is suitable for use in interior or exterior settings and achieves a full cure in 24 hours.

Cracks and missing chunks were filled with AB Original, which can just about be identified as the off-white colour down the centre of the stonework

The putty was kneaded by hand until it turned a uniform colour. It was then shaped and formed to replace missing areas of stonework and pushed into cracks. For shallow cracks, the surface of the curing putty was wetted whilst still pliable to create a type of slurry which could be worked further in.

To help disguise larger sections of AB Original, powdered dust from the stonework was pressed into the putty. This took it from its standard off-white and towards the colour of the fountain, helping the repaired areas blend in.

Once the repair was completed, the water fountain retuned to full working order

The owner even discovered that painting yoghurt onto the fountain helped further disguise the repair by encouraging lichen and moss to grow. The distressed touch this added was in keeping with the original stone.

Once the repair and restoration had been completed, the end result was a robust and fully watertight upper bowl. The fountain could go back into use for the summer with any visitors to the garden none the wiser that just a few months earlier, it had been cracked into multiple pieces.

Case Study: Repair of Hairline Crack Around Diameter of Porcelain Toilet Soil Pipe

Wrap & Seal Pipe Burst Tape seals a hairline crack in a porcelain toilet waste pipe repair

Soil pipe sealing – Wrap & Seal forms a rubber ring to repair a porcelain toilet

A homeowner carries out a DIY pipe repair to a porcelain soil pipe which developed a hairline crack around its entire diameter after an unstable bathroom floor caused the toilet to shift away from the wall it was connected to.

Case Study Details

The porcelain soil pipe connected the bowl of the toilet with the sewer pipe behind. The increasingly unstable bathroom floor meant that whenever anyone sat on the toilet, it tilted forward and pulled the pipe away from its fixed connection to the back wall.

Eventually, the stress being put on the pipe by the frequent movement of the toilet caused a hairline crack to appear around the entire diameter, through which water dripped whenever the toilet was flushed. This had the potential to make the floor even more unstable.

The crack caused by movement of the toilet pulling the porcelain soil pipe away from its connection to the bathroom wall

The homeowner was planning a full bathroom renovation to address the floor issue, which would include replacing the toilet. They therefore wanted a quick, easy and cost-effective DIY method to repair the porcelain soil pipe until said renovation took place.

There were several challenges with the repair. The crack was too thin to force epoxy putty into and was located on a bend in a difficult position, close to the back wall and with minimal space between the pipe and floor.

The continued movement of the toilet also had to be taken into account. Any repair needed to offer a degree of flexibility, as rigidly fixing the pipe back in place would leave the potential for cracks to develop elsewhere.

Sylmasta recommended encompassing as much of the pipe as possible with Wrap & Seal Pipe Burst Tape to create a watertight rubber ring bonded to the porcelain. This would seal the leak, allow the pipe an element of movement to reduce stress, and prevent water escaping from any other cracks which developed elsewhere in the porcelain.

Wrap & Seal is made from self-amalgamating silicone which fuses to itself to form a solid rubber band as it is wrapped around a pipe. One 50mm x 4m tape was enough to cover the leak and the surrounding area susceptible to future cracks.

Despite the space constraints between the back wall, the floor and the toilet bowl, the homeowner was able to stretch the tape to three times its length whist wrapping, creating maximum tension.

The tape easily fused, fully sealing the leak and preventing any more water escaping when the toilet was flushed. Completing the porcelain soil pipe repair took less than 15 minutes and cost under £30, including delivery of the Wrap & Seal Pipe Burst Tape.

Case Study Details

The pipeline was 100mm in diameter and ran for 365 metres through the plant, carrying natural gas produced by a combined heat and power system. It was hung on a series of U-shaped supports welded to I-beams suspended from the roof of the building.

When originally installed, the pipe had been wrapped with a protective PVC tape. Unfortunately, incorrect application of the tape had left a three-metre section where it was possible for water and condensation to become trapped between the tape and the line.

Removal of the yellow PVC tape revealed very heavy corrosion to the steel pipe

This had led to heavy corrosion, which was particularly prevalent at the bottom of the pipe and the area where the section in question rested on its U-shaped support. The weakened three metres of the natural gas pipe now required strengthening and repair before the steel became breached.

The pipe was cleaned of paint and grime before repair of the corroded surface

The plant decided to use the Sylmasta Pipe Refurbishment System to bring the damaged section of the line back up to specification, by reinforcing the metalwork and giving the pipe greater protection against future corrosion.

First, the U-Shaped support was cut away from the I-beam to enable better access to the corroded area. The PVC tape was removed and rust, grime and paint ground off. Alcoholic cloths were then used to remove any remaining residue from the grinding process.

Liquid Metal applied to repair a natural gas pipe suffering from heavy exterior corrosion
Liquid Metal was brush applied across the three metres of the pipe suffering from corrosion

To repair the damage and restore the pipe exterior, the three-metre section was coated in Liquid Metal Epoxy Coating. Liquid Metal is brush applied and cures to form a smooth, metallic, hard-wearing outer surface which acts as a shield against external corrosion and chemical attack.

The 90-minute gel time of Liquid Metal allowed significant amounts of epoxy to be mixed and painted on without the threat of premature curing. A SylWrap HD Pipe Repair Bandage was then wrapped around the area of the line which had contact with the U-shaped support.

SylWrap HD Pipe Repair Bandage applied to a heavily corroded steel natural gas pipe
SylWrap HD was wrapped around the area of the pipe which came into contact with the U-shaped support, which was to be welded back in place to the I-beam above

SylWrap HD is a composite repair wrap with a water-activated resin. It was applied whilst the Liquid Metal remained tacky and cured within minutes to form a rock-hard, impact resistant outer shell around the pipe. This further increased the thickness of the weakened section and provided an additional layer of protection.

A second layer of Liquid Metal was applied across the three-metre section, including over the SylWrap HD. Although an additional coating on top of the composite bandage is not a required step of the Sylmasta Pipe Refurbishment System, the plant wanted to make the line look aesthetically pleasing with a final metallic finish.

A second Liquid Metal coating was applied over the SylWrap, the U-support welded back in place and the pipe fixed to it via a support clamp

Once the pipe had been refurbished, the removed U-shaped support was welded back to the I-beam. The line was then fixed to the U-shape via a new pipe support clamp fitted to prevent movement caused by vibration. The clamp was also coated in Liquid Metal.

Refurbishing the pipe was carried out with no impact to operations at the plant. It prevented an expensive and disruptive future repair or replacement being needed when corrosion eventually ate through the line.

The ultra smooth finish provided by Liquid Metal compared to the pitting caused by corrosion

The plant were very happy with the outcome and how easy their maintenance team found the application. They are now intending to use Liquid Metal to extend the lifespan of other pipes and structures at both this facility and across other sites.

Case Study Details

The 150mm steel pipe ran water out of the pumping house. The saddle joint had been welded in place to reinforce a capped tee and sat approximately 20mm higher than the original line. One end of the joint was suffering from heavy corrosion.

Water had been found seeping from both ends of the joint, leaving the pipe surface noticeably wet and the ground beneath the pipe sodden. The pipe could not be isolated or replaced because this would involve shutting down the pumping station.

Several repair attempts had failed, including a clamp

One end of the saddle joint was suffering from heavy corrosion whilst water was seeping from both

Several repair attempts had been made using different methods by the water company operating the facility, including the use of a clamp and epoxy putty, but none had been successful. The pipe had therefore been left to leak.

Whilst on a visit to Malaysia, a technician from Sylmasta was asked to accompany a engineering team to inspect the pipe and see if a solution could be formulated. They recommended using Wrap & Seal Pipe Burst Tape to start a repair on the original steel pipe and build it up and over the weld, encompassing and sealing either end of the saddle joint.

The pipe was cleaned and prepared before repair

First, an angle grinder was used to sand down the pipe, clean it of loose material and remove corrosion. A first Wrap & Seal Tape was then applied directly next to the step. Wrap & Seal is self-amalgamating and stretches by three times its length, fusing together to form a solid rubber band.

Diagram explaining how to repair a leaking saddle joint weld with a step using Wrap & Seal Pipe Burst Tape
Wrap & Seal application started on the pipe next to the saddle, was built up until level with the step and then continued across onto the joint

With each rotation, the Tape moved closer to being level with the top of the saddle joint. The application continued until enough Wrap & Seal had been applied to bridge the 20mm step between the pipe and the saddle.

Once this had been achieved, Wrap & Seal was applied 50mm across the saddle to achieve a good connection. It was then returned to directly over the edge of the joint.

Once Tape had been built up and over the saddle, wrapping continued immediately over the leak area
Wrap & Seal Pipe Burst Tape applied to a leaking saddle joint in a successful repair despite a 50mm step being present

Here, a ridge was created directly over the leak area to increase the pressure resistance of the repair. It was estimated that three Wrap & Seal Tapes needed to be used to seal one end, after which the process was repeated at the other end of the saddle joint.

Because the welded saddle joint had been seeping water slowly, the only way to check whether the application had been effective was to inspect several days later. When the pipe surface was found to be dry, the repair was deemed a success.

Case Study Details

Showerking are a Sussex-based supplier of portable hot shower units designed for horses and dogs. Units are typically stored in unheated outbuildings. Although designed to handle winter weather, copper pipe in the unit which has not been fully drained becomes prone to bursting during periods of exceptionally cold weather.

When temperatures in the United Kingdom dropped as low as -15°C, several Showerking owners reported burst pipes which rendered their units unusable. If they turned the shower on, water would spray out of the large crack created in the copper pipe.

Freezing temperatures had created a split in the copper pipe

Fortunately, Showerking had already contacted Sylmasta about the possibilities of pipe repair for horse showers. The SylWrap Standard Pipe Repair Kit provided the most suitable method as units would be turned off in the event of leaks or bursts, meaning no pressure to the pipe.

It had been established that the smallest Standard Pipe Repair Kit (SYL-106-NP) was ideal for application because of both the cramped space inside the unit and the difficult shape of the pipework. There were many bends which were unrepairable with a clamp.

Through the relationship between Showerking and Sylmasta, users whose horse showers had suffered burst pipes were directed to the exact product they needed to fix the problem, and had the straightforward repair process explained to them.

Loose material was removed from the burst copper pipe before repair. Superfast Copper Epoxy Putty Stick was then used to seal the crack. Enough putty to cover the crack was cut from the stick and kneaded by hand until it turned a uniform colour.

Whilst soft, the putty was pushed onto the pipe, encompassing the entire crack. This completed the first stage of the repair. The second stage involved applying a SylWrap HD Pipe Repair Bandage over the Superfast Copper.

SylWrap HD is a composite repair wrap with a water-activated resin which sets rock hard. The bandage was wrapped and smoothed around the pipe as the Superfast Copper began to harden, forcing the putty into the crack to create a permanent, watertight seal.

Within five minutes of SylWrap HD being applied, the bandage had cured to form a rock hard shell reinforcing the pipe, and which also offered protection from expansion in the future. The completed repair was resistant to 30bar, making it more than capable of holding the pressure the horse shower unit operated at.

The repair took less than 30 minutes from start to finish and the SYL-106-NP Standard Pipe Repair Kit cost under £25 including delivery, returning the £180 Showerking unit to service the same day.

Case Study Details

The plant collected gasses produced during the extraction of crude oil – such as propane, butane, methane and ethane – and converted them into a number of different chemicals exported worldwide for industrial and agricultural use.

Seawater was extracted from the Persian Gulf and stored in vast metal tanks for use in cooling and other processes on site. The interior of each tank was concrete coated and then lined with rubber matting for protection against corrosion.

Problems with one tank led to it being drained for inspection. This revealed sections of the rubber matting on the floor of the tank had become loosened, lifted and completely broken apart in some places, leaving the concrete lining exposed.

The rubber matting of the tank floor had become damaged, exposing the concrete coating below

There was a risk that this exposure could lead to seawater finding a way through the concrete and coming into contact with the metal frame beneath. This would put the tank in danger of serious and irreparable damaged caused by corrosion. All gaps in the rubber sheeting therefore had to be sealed before the tank could go back into service.

The engineering team carrying out the seawater tank repair decided to use Sylmasta AB Original Epoxy Putty for the application. AB Original is ceramic-filled, making it stronger and harder wearing than other epoxy putties. It is fully waterproof, adheres to wet surfaces and its high chemical and corrosion resistance mean it is often used as a sacrificial layer.

AB Original was mixed by hand. Whilst soft enough to shape and manipulate, it was forced into the gaps and cracks between the rubber sheeting and smoothed off with water and a hand tool.

The two hour work time of AB Original allowed large amounts of putty to be mixed and applied without the threat of premature curing. Once hardened, the putty permanently filled every gap with a waterproof material, protecting the concrete lining from seawater exposure.

The repair was completed by coating fibreglass sheets with an epoxy to form a new protective surface over the damaged rubber matting

After the application of AB Original, fibreglass sheets were layered over the rubber matting and coated with an epoxy resin. This created a new reinforced floor surface over the damaged rubber, offering yet another layer between seawater and the metal frame of the tank.

The plant could then put the tank back into operation safe in the knowledge that the metalwork was now far better protected by a combination of concrete, AB Original, rubber matting and an epoxy composite repair.

Case Study Details

A potential leak was identified on a section of the water supply network running beneath a street. Excavation took place and revealed a cement coated steel pipe suffering from a crack around 15mm wide across the diameter of its outer coating.

There was no sign that any water had escaped through this crack. To inspect the condition of the pipe inside, engineers removed the cement using a hammer and chisel. As the coating was chipped away, water began spraying out from a 80mm long split in the steel pipe.

As the coating was removed, water began spraying out from a split in the steel pipe

By the time the cement coating had been fully removed from around the leak area, enough water had escaped into the excavation hole to half-submerge the pipe. There was no means of isolating this section of the network and so the only option was to make a live leak repair.

The specialist company involved in the identification of the leak and excavation of the pipe equip all their engineering teams with SylWrap Pipe Repair Contractor Cases, meaning everything needed to seal the pipe was already on-site.

Contractor Cases contain enough WRAS approved products to make up to six permanent live leak repairs to pipes of all diameters and materials. WRAS approval was necessary for this application because the pipe carried potable water.

A bucket was used to remove enough water from the hole to enable the repair to take place. Wrap & Seal Pipe Burst Tape was used to seal the leak in the line, with several Tapes applied to cover the entire length of the split in the steel.

When stretched and wrapped around a pipe, Wrap & Seal fuses to itself to form a solid rubber band. Multiple Tapes can be applied over each other to build pressure resistance up to 30bar. For this repair, the requirement was around 3bar.

Enough Wrap & Seal Tapes were applied until the leak had been fully arrested. A SylWrap HD Pipe Repair Bandage was then wrapped over the top for the purpose of reinforcing and protecting the initial repair.

The pipe was successfully sealed in under an hour

SylWrap HD is a composite wrap with a water-activated resin. After being wrapped and smoothed around the pipe, the bandage set rock hard in minutes. The impact resistant sleeve formed by SylWrap provided an effective replacement for the removed cement coating.

The application was completed in under an hour. Having all the products required to repair the cement coated pipe ready and available via the Contractor Case made a significant difference to response time and how quickly the leak could be sealed, reducing the amount of water lost and disruption to supplies.
