The most important stage of tunnel construction is the PVC geomembrane waterproofing process. It is cheaper to prevent the passage of water with a PVC geomembrane than to carry out maintenance or operation works to channel the already filtered water to the structure.
It is a product designed to be an excellent barrier against water and has the following characteristics that make it an efficient solution when waterproofing:
In our engineering line we produce calendered PVC geomembranes, widely used in waterproofing, containment, insulation and protection applications for a variety of markets.
Being a calendered product, it has all the advantages of the technology: uniform thickness throughout the length and width of the roll product, excellent flatness and very low shrinkage.
