Drain Linings & Patch Linings

Drain Repair With Minimal Disruption

We can deliver a ‘no dig’ service to avoid unnecessary excavation and disturbance. Using a patch lining, we can make long-lasting repairs to your drain with minimal disruption and exceptional results.

This process involves installing a new resin liner within an existing damaged pipe.

There are numerous situations where the re-lining process has advantages over drain excavation and repair, not only are there financial benefits but also our customers are pleased with the minimum disturbance to their properties and routines (due to the speed of repair).

Drain lining is particularly useful where an existing clay pipe is cracking as it helps restore structural integrity and prevents soil erosion due to liquid exfiltration, also where root infiltration to the drain occurs a resin liner can often stop future ingress as it is a jointless pipe that denies roots an obvious point of entry. 

Surface Water Drainage

Flooding From Rain water

As flash flooding is becoming more of a problem, it is important to keep your rain water drains clear (down pipes, surface water gullies, aco slip drains and soakaways).

NRG Powerjet can carry out all maintenance work to your surface water systems, to prevent any flooding or damage to your property.

We can also install anti-flooding values to prevent back surges of rainwater into your property when the main drains are overflowing.
