Structural Drain Lining / Patch Lining
Cracks and open joints are the most common drain damage that occurs with root ingress, water infiltration, gound movement and traffic tend being the main causes. Our re-lining service is a proven method of placing a new pipe within an existing damaged pipe – without the need for excavation.
The new pipe liner material is superior in quality and strength to the pipe in which it lies. The new pipe is moulded inside the damaged pipe using either air or water pressure – fitting it tightly against the wall of the existing pipe. When the process is complete the new pipe becomes rigid – resulting in a strong and durable pipe only 6% smaller in diameter than the original.
The re-lining process is suitale for sewers, drains and vertical downpipes. The products used in this process are resistant to chemicals and high temperatures.
