For more than 40 years, the waterproofing sheets of the CARFOAM® system have been used in tunnels and underground works in Spain and abroad both in the construction of new structures and in the rehabilitation of old structures. During this time, more than 2 million square meters of these waterproof sheets have been placed, so we have numerous reference projects.
The CARFOAM® sheet has a multilayer structure, in which one of them provides a different function. The exposed outer layer provides mechanical strength, the intermediate layer the degree of thermal insulation desired by a closed-cell foamed sheet, and the inner layer mechanical strength, weldable surface and drainage. Depending on the final application, the structure of the layers can be modified to optimize performance.
Generally speaking, the individual layers perform the following functions:
The CARFOAM® system offers a series of advantages both from a general point of view and in particular cases.
