Enhancing Impermeability, Waterproofing, and Salt Resistance

Enhancing Impermeability, Waterproofing, and Salt Resistance

Water infiltration is the leading cause of reinforcement corrosion, efflorescence, and freeze-thaw spalling in reinforced concrete. Modifying cementitious formulations with RUICO 9608A SBR Latex creates an impermeable barrier against moisture and aggressive chemical agents.

In unmodified cement mortar, water evaporation leaves an interconnected network of capillary pores. Under hydrostatic pressure or capillary suction, these pores transport water, de-icing salts, chlorides, and atmospheric carbon dioxide into the structure. When RUICO 9608A is incorporated, polymer particles migrate toward drying surfaces and capillary channels, coalescing to physically plug microscopic pores.

This film network substantially lowers water absorption and chloride diffusion rates. As a result, 9608A-modified mortars are well-suited for waterproofing slurries, basements, wastewater treatment plants, and marine infrastructure. Furthermore, the elastic nature of the SBR polymer absorbs tensile stresses during freeze-thaw cycles, preventing microscopic matrix micro-fissuring.

For civil engineers designing coastal structures, bridge piers, or retaining walls exposed to aggressive groundwater, adding RUICO 9608A to protective coatings and mortar layers provides essential durability and extended service life.
