SylWrap Pipe Repair Contractor Case-
Make Multiple Emergency Repairs

Designed for regular pipe repair users, the SylWrap Contractor Case stores enough products to make up to six emergency live leak repairs in a robust, easy-to-carry red case which can be conveniently kept on-site or on the van.

Whenever an emergency repair is required, the user simply has to reach for their Contractor Case where they will find everything they need to perform a permanent leak repair in under 30 minutes. No training is required, simply follow the instructions provided.

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, and they are approved by the national supplier in Malaysia for use on Kuala Lumpur’s vast pipe network.

Repairs can be made to pipes of all diameters made of steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber, and lead. The Case can make repairs pressure resistant up to 30 bar, temperature resistant to 200ºC, and is used on pipes carrying hot water and chemicals.

Effective repairs can be made around difficult elbow joints, tee joints and welded joints, offering a flexible alternative to heavy, bulky pipe repair clamps.

All the products in the Contractor Case have WRAS Approval, meaning they are certified to British standards as safe to use on pipes carrying drinking water.

Fixing pipes using a Contractor Case costs a fraction of carrying out a pipe replacement. Aside from the water industry, the Case is used by sectors where significant pipework systems are present, such as wastewater treatment works, petrochemical plants, and oil rigs. Maintenance management companies stock Cases to enable rapid pipe repairs to be made to the facilities they are responsible for.

SylWrap Pipe Repair products are WRAS approved, one of the highest pipe repair accreditations that a product can achieve

How to make an emergency pipe repair with a SylWrap Contractor Case

Each SylWrap Pipe Repair Contractor Case contains two sealing materials – Superfast Steel Epoxy Putty and Wrap & Seal Pipe Burst Tape – and a SylWrap HD Pipe Repair Bandage.

Superfast Steel is an epoxy putty in a pre-formatted stick. It seals holes and cracks in pipes where water pressure can be turned off, restores surface profile on pipework badly damaged by corrosion or pitting, and removes step from joints prior to the application of Wrap & Seal.

To use, Superfast Steel is kneaded by hand until it turns a uniform colour. It is applied whilst soft, smoothed over pipework for surface restoration or pushed into cracks for leak sealing. Within 5-10 minutes, it will harden.

Wrap & Seal Pipe Burst Tape is a waterproof pipe repair tape made from self-fusing silicone. When pressure cannot be turned off, it is anchored next to and then wrapped directly over the leak area.

The Tape stretches by 300 percent, fusing into a solid rubber band which provides a high pressure seal over the leak. Multiple tapes applied on top of each other will fuse together, creating a live leak repair pressure resistant up to 30bar.

After application of the sealing material, the repair is reinforced with a SylWrap HD Pipe Repair Bandage. Wetting the Bandage activates the resin. The Bandage is wrapped around and smoothed over the pipe with water, where it will set to provide a rock-hard, impact-resistant, protective layer.

There are different configurations of Contractor Case available designed for use with different pipe diameters. For a breakdown of what each Case contains and the pipe size Sylmasta recommend its use with, please see the Size Guide.

For high-pressure repairs, please use the Repair Calculator to input your data. The Calculator can then determine the required quantity of Wrap & Seal and coverage of SylWrap HD for your application.
