Waterproof membranes
Tank liner

PVC tank liners consist of a membrane inserted into the tank that will protect it from harsh chemicals. The PVC membrane creates a barrier between the liquid and the tank which inhibits corrosion of the tank. The soft and flexible nature of the PVC makes it easy to install on new or existing tanks.

The special designed PVC formulation makes it easy to weld.

It is also available in transparent form for easier control of the welding process
