From our experience in testing and assessing concrete structures, we have found that there are various causes of concrete deterioration. Concrete is a composite material consisting of various elements, such as coarse aggregate, which is bound together with liquid cement that will harden like a stone over time. Although concrete looks solid, it is porous and can be penetrated by liquid. Pores, cavities, and capillary pathways can carry water and aggressive chemicals into structural elements, which will then damage steel and concrete, thereby damaging structural strength.
The penetration of aggressive substances into the concrete through interconnected pores, coupled with cracks, causes material degradation and structural damage. Depending on the type of substance penetrating, the attack can occur on concrete or steel reinforcement. The dominant factors causing damage to reinforced concrete structures are carbonation and diffusion of chloride ions, which cause corrosion in steel reinforcement.
Xypex Crystalline Technology is a unique, non-toxic solution for concrete waterproofing and concrete protection. Xypex's primary and most distinguishing performance feature is its unique ability to generate a non-soluble crystalline formation deep within the pores and capillary tracts of the concrete - a crystalline structure that permanently seals the concrete against the penetration of water and other liquids from any direction. By preventing the penetration of aggressive chemicals, Xypex Crystalline Technology helps control the problems of sulfate attack, leaching, alkaline aggregate reaction, carbonation, and chloride-induced corrosion.
A key feature of Xypex is that its crystalline formation becomes an integral part of the concrete, providing completely sealed and impermeable concrete thereby enhancing the durability, long-term structural integrity, and protective capacity of the structure.
