A liquid admixture that protects waterproofing, reducing capillarity of concrete and mortars, making them waterproof with low water absorption.

Features

• very easy to use as it is added to the mixing water
• the resulting concrete and mortar are waterproofed
• prevents salt from appearing on the surface

Application

• obtaining non-absorbent mortars and concrete regardless of capillarity or pressure
• external or internal, waterproof rendering for concrete blocks, bricks, concrete
• scratching tank in, swimming pool in the basement, elevator shaft, well and channel in
