Leak Sealant

Stage 1 of the Sylmasta Pipe Refurbishment System

Sylmasta Leak Sealant products repair holes and cracks in burst and leaking pipes, forming the first stage of the Sylmasta Pipe Refurbishment System.

Repairs can be made which are pressure resistant to 30 bar and effective on pipes of all diameters made from steel, copper, plastics, malleable iron, GRP, ceramic, clay, concrete, rubber, and lead.

Where pressure cannot be turned off, Wrap & Seal Pipe Burst Tape is wrapped around pipework, fusing into a solid silicone rubber band which seals live leaks.

For live leaks on pipes in excess of 150mm diameter, SylPad Pressure Resistance Multiplier is used in conjunction with Wrap & Seal to increase the pressure resistance of the Tape.

When flow can be isolated, 114g Superfast Epoxy Putty Sticks make fast repairs to small holes and cracks in offline pipes. Different formulations are manufactured for specific pipe substrates with most Superfast Sticks having a work time of five minutes or less.

Sylmasta AB Original Epoxy Putty comes with a two-hour work time, enabling greater quantities of putty to be mixed and more careful application without the threat of premature of curing.

AB Original is used in more complex, larger applications. It is supplied in either a ready-to-mix 200g stick or as a two-part epoxy with separate components of resin and hardener up to 50kg, which require measuring before mixing.

Sylmasta AB Rapid 5 Minute takes the fast work time of a Superfast Epoxy Putty Stick and combines it with the two-part format of AB Original.

CrackSeal is a specialist sealant for repairing cracks and splits in low-pressure cast iron pipes. It is extruded directly into areas of damage using a standard sealant application gun, where it will form a waterproof material.

Wrap & Seal, Superfast Steel, Superfast Aqua PW and Superfast Copper have WRAS approval, meaning they are certified to British standards as safe for use on pipes carrying drinking water.
