To prolong the life of bridges, roads and natural stone house fronts, they must be protected against moisture. Rainwater in the pores is an ideal breeding ground for algae, mosses and fungi. Open pores can also cause damages through crystallisation of salts and through frost.

A hydrophobic treatment protects the surface for a longer time. Repairs are needed less often and resources are saved. The CHT Group offers innovative products for the surface protection of infrastructural buildings.

We develop, elaborate and provide solutions that specifically match customer demands.
