REBOTEC Waterproof is a powder admixture for waterproofing concrete and mortars. REBOTEC nanoparticles react with cement during the hydration process, utilising natural mineral substances to block the capillary network, repel water, and provide a high level of impermeability to concrete or mortar.

REBOTEC Waterproof is 100% mineral, non-toxic, non-polluting and safe to touch without the need for additional PPE.


When using REBOTEC Waterproof as an additive to your concrete, the finished concrete product repels water and becomes truly non-porous. As long as the integrity of the concrete structure remains intact, there is no degradation in the water-proof qualities of the finished product for its intended life-span.
