Description

Cement additive, designed to completely stop and prevent water and moisture leakage through concrete and mortar covering bricks. WR is supplied in dry powder form, ready to mix with water and cement. WR should be applied to cement surfaces, concrete or mortar. WR resists positive as well as negative water pressure, so WR can be applied to the inner or outer side of the wall or slab.
Action:
WR contains some chemical elements which react with the calcium carbonate –found in cement- and produce fine crystals of calcium silicate – glass like material- these crystals fill the voids in concrete or mortar flesh blocking water and moisture seepage.
