Major penetrating waterproofing mixtures represent dry mixtures of cement and sand having admixtures, or systems of mineral salts, used to block the structure of capillaries and pores of cement mortars and concretes. Thin layers of waterproofing mortars are applied to sufficiently porous surfaces. As a result, the water content is reduced in the course of hardening. This process causes contraction and cracks in the coating.The findings of the research performed by the authors have proven that waterproofing materials containing wollastonite-based Antigidron system comply with each basic requirement applicable to penetrating waterproofing materials, as their admixtures penetrate into the concrete to seal concrete pores and to generate insoluble crystals.The new Antigidron system has the following strengths. Each component of the proposed system is made in Russia. It has efficient operating properties, and its cost is1.5 — 2 times lower than the one of similar products.
