Description
Topkrete PenetraCryst is high-performance crystalline waterproofing admixture designed to enhance the durability and impermeability of concrete. When added to fresh concrete, PenetraCryst reacts with moisture and unhydrated cement particles to form insoluble, needle-like crystals that block capillaries and micro-cracks. This intergral waterproofing mechanism provides permanent protection against water ingress, chemical attack, and chloride penetration. PenetraCryst becomes an integral part of the concrete matrix and remains active for the life of the structure.
Area Of Application:
Suitable for both above and below grade structures, including:
- Water tanks, reservoirs, STP/WWTP structures
