Ideal for swimming pools, water tanks and basement walls, our waterproofed concrete is produced with the inclusion of crystalline admixtures that maintain water impermeability for the entire life of the structure.
When combined with water and concrete, the admixture reacts with un-hydrated cement particles to form millions of needle-like crystals. Over weeks and months, these crystals grow, filling the naturally occurring pores and voids in the concrete, permanently blocking the pathways for water and waterborne contaminants. If cracks form later due to settling or shrinkage, incoming water will trigger the crystallization process and additional crystals begin to grow, filling cracks and ensuring that the structure’s waterproofing barrier is maintained and protected.
In addition to filling the pores and capillaries of the concrete matrix with crystals, the admixture enhances the natural hydration process by intensifying and prolonging the hydration of the cementing materials. This reduces the size and number of capillary pores within the concrete matrix, making it dramatically less porous and improving strength & durability characteristics.
