Drain Lining Explained
Pitched fibre pipes
As well as root ingress, some other problems occur especially with pitched fibre pipe work. This type of pipe work material was used from the early 1960’s. These pipes begin to weaken causing the pipes to become deformed in their shape – i.e. ‘oval’ in shape and blistering occurs inside the pipes. This deformity can cause various blockages, and will eventually lead to full closure or collapse of the pipe work, leaving the drain system non-functional.
Before this happens, and if caught early enough, we can re-line the drainage system using cold / hot cure polyester lining system specifically designed for this task. This will then strengthen the integrity of the pipe work and prevent further problems.
Common clay pipes
These pipes suffer from tree root ingress and structural cracks. This will then cause the drain to leak which can lead to subsidence to nearby buildings.
We can remove the tree roots ingress (see root cutting page) using remote cutting equipment inside the drain. We would then carry out high pressure jetting to further remove any deposits of fat or grease, etc. prior to re-lining.
Using the latest technology we are often able to re-line the damaged sections of pipe work without any excavation or disruption to surfaces.
This process involves inserting a resin impregnated felt liner into the drain, cut to length, and inserted over the damaged sections. An inversion tube is then inserted into the felt liner and filled with compressed air until it takes the shape of the host pipe. This is then left to set. Once set the inversion tube is deflated and retrieved, leaving a smooth GRP liner with no joins, thus preventing any further tree root ingress and vastly improving the structural integrity of the clay pipe work.
