SylWrap Pipe Repair Contractor Cases contain all the equipment and products needed to carry out multiple pipe repairs to live leaks
The SylWrap Pipe Repair Contractor Case contains enough products for water companies and facilities managers to carry out up to six emergency live leak pipe repairs

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, just 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 leaks once detected. They also are approved by the national supplier in Mexico, and in Malaysia for use on Kuala Lumpur’s vast pipe network.

The Contractor Case repairs pipes of all diameters made of steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber, and lead. Repairs are pressure resistant up to 30 bar, temperature resistant to 120ºC, and effective on pipes carrying hot water and chemicals.

Repairs can be made around difficult elbow, tee 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. Cases are also used in the marine industry, from super yachts to cargo ships for repairs both at sea and in dry dock.


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

Each SylWrap Pipe Repair Contractor Case contains two different sealing materials – Superfast Steel Epoxy Putty and several Wrap & Seal Pipe Burst Tape – and multiple SylWrap HD Pipe Repair Bandages.

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 30 bar.

For high-pressure repairs, please use the Repair Calculator to input your data. The Calculator can then determine the quantity of Wrap & Seal needed for your specific application.

Contractor Cases covering pipework in excess of 150mm include SylPad Pressure Resistance Multiplier. SylPad is used in conjunction with Wrap & Seal to better concentrate the elastic force of the Tape directly over holes up to 20mm on larger diameter pipes, multiplying pressure resistance by up to three times.

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.

Unlike other moisture cured wraps, SylWrap HD contains less than 0.1% low free diisocyanate. This means it is not covered by the 2023 EU and UK REACH legislation governing the safe use of diisocyanates and requires no mandatory safety training before use. At the same time, the low hazard formulation reduces risk to operators.

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.

If you require further information about the most suitable Contractor Case for your type of application, please fill out the enquiry form below and a technician will be happy to advise. If you do not see a Contractor Case listed which meets your requirements, Sylmasta can also offer customised Cases tailor-made to your specific needs.

Repair Calculator

Wrap & Seal Repair Calculator

The below Wrap & Seal Calculator can be used to determine the recommended number of Wrap & Seal Pipe Burst Tapes required to seal a live leak based on pipe diameter and pressure.

Enter the diameter of the pipe in millimetres, water pressure and the size of the hole requiring sealing in millimetres. The safety factor is a multiple to include a margin of safety. For example, if pipe pressure is 5 bar and you want a safety factor of two, the calculator will formulate a repair capable of withstanding 10 bar.

After entering your data, selecting the size of Wrap & Seal will determine how many of that specific tape are required for your repair. Repairs being made to pipes in excess of 150mm diameter using Wrap & Seal PB-50x4m or PB-50x11m should be made in conjunction with SylPad.

Calculations serve as a guide to potential maximum pressure resistance only. Actual pressure resistance depends upon pipe material, condition, hole size, leak type and tension maintained during wrapping. If you are unsure, more than one Wrap & Seal can be used to stop the leak.
