Wrap & Seal Pipe Burst Tape
Wrap & Seal Pipe Burst Tape is a self-amalgamating waterproof pipe repair tape capable of sealing live leaks on pipes of all types and diameters.
As it is wrapped around pipework, Wrap & Seal fuses to itself to form a solid rubber band. This rubber band exerts pressure over the leak to contain pipe content.
Additional tapes applied on top of each other will amalgamate in the same way. It is possible to build a repair capable of holding up to 30 bar pressure with multiple Wrap & Seals.
It is twice the thickness of other waterproof tapes and can be stretched by a maximum of 300 percent of its length, allowing for more pressure to be applied per wrap. Repairs made with Wrap & Seal are therefore faster and more effective.
Wrap & Seal also features a unique tapered profile which maximises surface contact and enables better amalgamation during wrapping. A central white guideline down the middle of the pipe repair tape ensures each wrap accurately overlaps by 50 percent.
Because Wrap & Seal is effective on live leaks, it avoids costly and disruptive shutdowns of systems. It requires no training before use – simply follow the instructions provided.
Wrap & Seal is used in applications ranging from small domestic plumbing problems to large scale industrial pipe repairs. It repairs steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber and lead.
It has WRAS approval, meaning it is certified to British standards as safe to use on pipes carrying drinking water. Wrap & Seal is temperature resistant to 200ºC and effective on pipes carrying hot water and chemicals

How to fix a leaking pipe using Wrap & Seal Pipe Burst Tape
Fixing a leaking pipe with Wrap & Seal Pipe Burst Tape is straightforward. Repairs can be made in under 15 minutes depending on the diameter of the pipe and the number of tapes needed to reach the required pressure resistance.
The repair begins by anchoring Wrap & Seal next to the leak area. Using the centre line of the pipe repair tape as a guide, users stretch it to its maximum and wrap tightly towards and then directly over the hole in the pipe.
Application continues until the entire first roll of Wrap & Seal is used regardless of if the leak stops midway through.
As you apply Wrap & Seal, it fuses into a solid rubber band, sealing the leak. The tapered profile stops water from tracking underneath the tape, maximising surface contact with the pipe.

Each layer of tape increases the pressure resistance of the repair. If the leak continues after one Wrap & Seal is applied, more tapes are added to increase the pressure resistance.
You can determine the number of tapes required before application based on pressure and pipe diameter using the Repair Calculator tab on this page.
SylPad Pressure Resistance Multiplier
Sylmasta recommend using a SylPad Pressure Resistance Multiplier in conjunction with Wrap & Seal for repairing holes up to 20mm on pipework in excess of 150mm diameter.
SylPad better concentrates the elastic force of the tape directly over the leak on larger diameter pipework, multiplying pressure resistance by up to three times. This enables a faster repair by reducing the number of tapes needed.
Reinforcement with SylWrap HD Pipe Repair Bandage
To reinforce pipe repairs made with Wrap & Seal, Sylmasta recommend overwrapping the tape with a SylWrap HD Pipe Repair Bandage.
SylWrap HD is a water-activated composite wrap. It sets rock-hard in minutes to form an impact resistant layer of protection covering Wrap & Seal for a permanent repair.
Wrap & Seal and SylWrap HD can be purchased together in the Universal Pipe Repair Kit or the Pipe Repair Contractor Case. The Universal Kit makes a single live leak repair whilst the Contractor Case contains enough tapes and bandages to seal up to six online leaks.

Wrap & Seal Pipe Burst Tape Repair Calculator
The below Wrap & Seal Calculator recommends the 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.
Once data is entered, selecting the size of Wrap & Seal determines how many of that specific tape are required for a repair. Repairs to pipes in excess of 150mm diameter with 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
Wrap & Seal Pipe Burst Tape Videos
Permanent pipe repair using Wrap & Seal and SylWrap HD Bandage
Sylmasta visit a UK water company to demonstrate the ease and speed of a permanent live leak repair using the products in a SylWrap Universal Pipe Repair Kit.
Wrap & Seal contained a 6 bar leak in a steel test pipe before overwrapping with SylWrap HD Pipe Repair Bandage.
Completing the permanent repair took under 30 minutes. The water company approved SylWrap Kits for use on their network shortly after.
Emergency live leak repair using Wrap & Seal Pipe Burst Tape
Demonstration video filmed at Sylmasta HQ to show the live leak repair capabilities of Wrap & Seal.
One 50mm x 4m Wrap & Seal sealed a pinhole drilled into a pressurised steel pipe before pressure was increased to 5 bar after the repair.
The solid rubber band formed by Wrap & Seal easily withstood the sudden pressure increase.
90-degree elbow bend live leak repair at 3 bar pressure
Demonstration video showing Wrap & Seal making a live leak repair to a 90-degree elbow bend on a section of pipe where it would be impossible to fit a repair clamp.
The inside elbow of a steel pipe was drilled into to create a pinhole leak and pressure set at 3 bar.
Wrap & Seal easily conformed around the elbow, forming a repair which was tested afterwards to withstand up to 10 bar.
Leaking step joint repair at Bahrain International Airport
The maintenance team at Bahrain International Airport make a live leak repair to a 100mm UPVC pipe leaking through a step joint.
Wrap & Seal was used to build a repair up and over the step, preventing water seeping out. SylWrap HD then reinforced the repair.
The application took under 30 minutes whilst the system the pipe was connected to remained operational, meaning there was no disruption to the airport.
Using SylPad to increase Wrap & Seal pressure resistance
Demonstration video showing SylPad increasing the pressure resistance of Wrap & Seal during a live leak repair to a 7.2mm hole in a 450mm steel pipe operating at 3 bar.
Such a repair without SylPad would require four 50mm x 4m tapes. Using SylPad, the leak was sealed with one tape.
With two further tapes added, the completed repair was capable of holding 9 bar pressure.
Threaded pipe joint repair resistant to 10 bar using Wrap & Seal with Superfast Steel Epoxy Putty
Instructional video showing a repair method formulated for a client to seal a threaded pipe joint in a system with maximum operating pressure of 10 bar whilst water leaked through.
Wrap & Seal removes step from the joint and exerts elastic force to push Superfast Steel Epoxy Putty deep into the thread.
Using tape and epoxy putty together provides a belts-and-braces approach, cutting off all leak paths for a high pressure repair.
