Used as part of flood prevention measures, we have developed our fully serviceable fit non-return valves to ensure the risk of damage is minimised. Call the experts at London Flood Prevention to find out more.
With many years’ experience, our engineers at London Flood Prevention can always find the most cost effective and least disruptive way to resolve any drainage repairs in London. No matter how big or small the problem, we can get the job done no matter what the scale.
Non Dig Technology
Drain relining has now become one of the quickest and cost-effective ways to repair your drains without the need for any excavation and mess in many situations. This latest technology can repair any type of drain, ranging from 100mm-150mm and can easily navigate round displaced joints and bends.
When the drain is initially being installed, we will clear any original debris or obstructions from the drain. Then a flexible liner, infused with resin is pushed through the pipe and moulded to the shape of the drain with a bag filled with compressed air. This pressure acts as a catalyst and heats the resin, so when the bag is removed it will leave a new drain within the existing run which is smooth and can even have an increased flow rate than before.
Sometimes, if there is only a small section of drain that is broken we can install a patch repair on the drain. This will work on the same principle as the reline, but applied to a specific section of the run rather than the entire drain.
