SylPad Live Leak Pipe Repair Pressure Resistance Multiplier
SylPad used in conjunction with Wrap & Seal Pipe Burst Tape increases pressure resistance during the live leak repair of holes up to 20mm on larger diameter pipework.
It is placed over the hole being sealed during the application of Wrap & Seal. It sticks to the tape without the need for any adhesive.
As layers of Wrap & Seal build up over SylPad, it changes the angle of the tape against the hole. SylPad directs more of the elastic force downwards, better concentrating the pressure resistance of Wrap & Seal directly over the leak.
Depending on pipe size, nature of the leak and repair quality, SylPad can increase the pressure resistance of Wrap & Seal by up to three times. It makes the tape more effective, reduces the number of Wrap & Seal required to reach high pressure resistance and speeds up repair time.
Sylmasta recommend SylPad for use with large Wrap & Seal (PB-50x4HD) or X-Large Wrap & Seal (PB-50x11HD) on pipes over 150mm, where changing the angle of the tape is of benefit.
Because SylPad is contained within layers of Wrap & Seal and does not come into contact with pipe fluid, it does not require WRAS approval for use with potable water.
How to increase live leak repair pressure resistance with SylPad
Wrap & Seal is a self-amalgamating repair tape which stretches by 300 percent. It seals live leaks by fusing into a solid rubber band during wrapping. This rubber band then exerts pressure over the leak to contain pipe content.
To use SylPad in conjunction with Wrap & Seal, the repair area is first marked with a pen. The user anchors Wrap & Seal 50mm to the side of the leak before wrapping towards the hole with a 50 percent overlay.
After reaching the leak, application continues directly over the hole to build up layers. The user adds SylPad after two layers, pushing it onto the tape covering the exact location of the hole as denoted by the pen.
SylPad adheres directly to Wrap & Seal for ease of placement. The application of Wrap & Seal then continues over SylPad with greater pressure now directed onto the leak rather than spread outwards.
Application of Wrap & Seal continues directly over the leak, building up a ridge. As each layer of tape fuses to the previous, so the pressure resistance of the repair increases.
If the leak continues after one Wrap & Seal is applied, more tapes are added. The application continues until the leak is completely sealed. It is possible to use multiple Wrap & Seals fusing together to build resistance up to 30 bar.
Reinforcement with SylWrap HD Pipe Repair Bandage
To reinforce pipe repairs made with Wrap & Seal and SylPad, Sylmasta recommend overwrapping 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.
SylWrap Universal Pipe Repair Kits 633 and 866 contain SylPad as standard. All SylWrap Pipe Repair Contractor Cases covering pipework 150mm upwards also include SylPad.

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. Instead, using SylPad reduced the number to one tape.
With two further tapes added, the completed repair was capable of holding 9 bar pressure.
