Patching

Drain lining is a fantastic method of repairing and sealing a pipe without the cost and inconvenience of excavation works.

But what happens if your pipe only has a small section damaged. What then?

At JS Drainage our vehicles are fully equipped with localised pipe repair kits which allows us to carry out simple pipe repairs while we are on site.

Localised Pipe Repairs work on the same principle as the relining system. The big difference is that the localised repair patch sleeve can be pushed to the damaged section of the pipe with rods (see diagram). Once the sleeve is in place over the damaged section of the drain it is then inflated to a set pressure while the Patch repair cures in place.

Benefits of relining and patch relining

• Quickly installed without excavation causing minimal disruption
• Forms a structural and durable new pipe within the old
• Bridges and seals gaps holes and gaps
• Resistant to chemical attack
• Resistant to corrosion
• Forms to any shape of pipe
• Improves flow characteristics
• Substantial cost saving over conventional reconstruction methods
• Environmentally friendly

Pipes suitable for patch repairs

• Clay
• Plastic
• Concrete
• Pitch fibre

Suitable applications

• Cracked or fractured pipes
• Pipes leaking at specific points or connections
• Bridging and sealing open or displaced joints
• Covering changes in pipe diameter e.g 150mm – 100mm

Localised pipe repairs can be carried out in varying sizes to cover pipes from 100mm – 1200mm.

We are able to supply a solution to all your relining needs and our advisers will be more than happy to discuss your Relining requirements.
