Lift Pit Liners - Trench Pit Liners

How to seal a lift pit
There are many problems when it comes to creating a watertight lift pit. These can include a high water table, shifting sand and weather conditions. Then there is the unpredictability of the onsite attempts at tanking and the costs of the contractor; attempting in difficult conditions to create a solid and dry base.

Here at Capvond Composites, we have many years experience within the civil engineering industry, supplying lift pit liners and trench pit liners. We are the experts in sealing lift pits. This is a one-stop answer to water ingress into one of the most difficult areas of lift shaft build. These custom made lift pit liners and trench pit liners are cost effective, 100% efficient and very easy to use, giving the contractor total confidence even in difficult build conditions.

Glass fibre trench liners provide an easy and quick solution to water ingress and a clean traffic system where pollutants can be detrimental to the equipment needed to be housed below. Our glass fibre trench pit liners provide a fast and efficient way of protecting high voltage cables, telemetric cabling or fluid pipelines.

Materials available include fire resistant, acid resistant and heat resistant, all manufactured to suit your individual needs.
