Concrete Admixtures

CHT Concrete Additives

The capillary water absorption of cementitious substrates can be reduced by using suitable hydrophobizing agents.

Besides the desired water repellence these agents additionally prevent negative effects such as salt efflorescence, mould formation and frost damage.
Cementitious substrates are thus given a longer durability and show maximum performance over a long period.

The aqueous, solvent-free emulsions of the CHT Group prolong the lifetime of concrete improving thus the sustainability of the building.
