Watch: How to permanently fix a leaking pipe when pressure cannot be turned off with a SylWrap Pipe Repair Kit

A SylWrap Universal Pipe Repair Kit enables the user to fix burst or leaking pipes in under 30 minutes when pressure cannot be turned off using a two-stage, permanent repair process.

Wrap & Seal Pipe Burst Tape is used to seal the initial hole or crack. Wrap & Seal is made from self-amalgamating silicone and stretches by 300 percent. When wrapped tightly around a pipe, it fuses to form a solid rubber band over a leak.

The Rape is anchored around 50mm to the side of the leak area. It is then wrapped towards the hole or crack with a 50 percent overlap. Once the point above the leak has been reached, the Tape is wrapped directly over it to build up a ridge.

As wrapping continues, the flow of water will diminish due to the pressure being applied by the Tape. If there is still leakage at the end of one Tape, more are applied until the leak is fully sealed. Multiple Wrap & Seal will fuse together, capable of building pressure resistance to 30 bar.

Once it has been established that water is no longer escaping the pipe, the application of Wrap & Seal is finished. Stage two of the process follows, where a SylWrap Pipe Repair Bandage is used to reinforce the initial repair.

SylWrap is a composite repair wrap with a water activated resin. Wearing gloves, the bandage is removed from the pouch. It is dipped in water for around five seconds, activating the resin.

The wetted SylWrap is applied to the pipe with a 50 percent overlap. As it is wrapped, the bandage is smoothed down in the same direction as it is being wrapped to maintain tightness.

Within a few minutes, it will begin to harden into a rock-hard impact resistant layer of protection encompassing the pipe. Once the bandage has set, the repair is completed.

Wrap & Seal and SylWrap Bandage both have WRAS approval, meaning they are certified as safe to use with drinking water. Repairs can be made to pipes of all substrates and diameters, are temperature resistant to 120ºC and effective on pipes carrying hot and cold water and chemicals.

A SylWrap Universal Pipe Repair Kit contains one Tape and one Bandage for making a single repair. For regular pipe repair users, Sylmasta have developed the SylWrap Contractor Case.

Each Case comes with enough Wrap & Seal, SylWrap Bandage and Superfast Epoxy Putty to make up to six live leak repairs. A Case can be easily stored on-site or on the van, equipping engineers with the products to make an emergency pipe repair as soon as problems are identified.

Several of the United Kingdom’s water companies equip their engineers with Contractor Cases for the speed and ease with which they repair live leaks once detected on the public supply network.

Contractor Cases are also approved by the national supplier in Malaysia for use on Kuala Lumpur’s vast pipe network, and by water companies in Mexico.

Industries away from water where the Case is used include tradesmen in the event of accidentally breaching a pipe, facilities management companies, ships and oil rigs.

The above video was filmed during a demonstration at a UK water company as part of the Sylmasta Pipe Repair Roadshow. A longitudinal split was cut into a steel pipe which was put under 6 bar pressure, before a Sylmasta technician showed how quick and easy it can be to fix a leaking pipe.
