Five drain repair techniques

Drain repair techniques play a crucial role in maintaining the functionality and efficiency of drainage systems. When faced with drainage issues, various methods can be employed to address the problem effectively.Drain excavation and repair

Drain excavation involves the physical digging of the affected area to access and repair the damaged drain. This method is suitable for severe issues such as collapsed or extensively damaged pipes. Although it can be time-consuming and disruptive, drain excavation allows for a comprehensive repair and replacement of the damaged section, ensuring long-term durability and effectiveness.

Drain lining (CIPP lining)

Drain lining, also known as cured-in-place pipe (CIPP) lining, is a ‘no dig’ repair technique. It involves inserting a resin-coated felt liner into the damaged drain. The lining is then inflated and cured, creating a new, durable pipe within the existing one. Drain lining Oldbury is a cost-effective and minimally invasive method that eliminates the need for extensive excavation.

Drain patch liners, spot repairs, or local patch repairs

For localised damage, drain patch liners or spot repairs offer a targeted solution. These techniques involve the application of resin-soaked patches to specific areas of the drain that require repair. The patches are cured to form a strong, watertight seal, effectively restoring the functionality of the drain.

Drain patch liners are especially useful for addressing isolated cracks, joint displacements, or small leaks. Specialist firms such as should be contacted for expert advice.

Pitch fibre re-rounding:

Pitch fibre pipes, commonly found in older drainage systems, can become deformed and misshapen over time. To restore their circular shape and optimal flow capacity, a process called pitch fibre re-rounding is employed. This technique involves inserting a bladder into the pipe and inflating it, exerting pressure to reshape the pipe back to its original form.

Pipe bursting

Pipe bursting is a trenchless technique used for complete pipe replacement. It involves the insertion of a bursting head into the existing drain, which breaks apart the old pipe while simultaneously pulling in a new pipe behind it. This method is effective for replacing damaged or deteriorated drains without extensive excavation.
