Compartmental joints

During the construction of underground structures, in the presence of water tables, waterproofing is achieved by means of synthetic membranes divided into compartments and welded together with FLEXVINIL® COM flat compartmental joints. This system allows to control water losses and also to perform local injections, in case of damage of the waterproof membranes.

The FLEXVINIL® COM compartmental joint is applied to ensure hydraulic sealing between the different sectors of the membranes. It is resistant to acid solutions, alkaline environments and salt water.
