CRYSTALS ADDITIVE

Concrete crystallizing waterproofing

Hidrolock ® Crystallizing Additive is a cementitious additive specially formulated to improve the impermeability of the concrete to which it is added. The active principles it contains give rise to a catalytic reaction in the core of the concrete that generates an insoluble crystalline material that precipitates in the pores and capillaries of said concrete structure, sealing them against the passage of water and causing a phenomenon of densification and waterproofing in the entire mass of concrete. In this way, the concrete is permanently waterproofed, both for positive and negative pressures, manifesting said impermeability even for high water pressures.
