Crystalline waterproofing technology is a method used to make concrete structures impermeable to water by inducing the formation of crystalline structures within the concrete matrix. The technology relies on the reaction between active chemicals and moisture present in the concrete. Here’s a breakdown of how crystalline waterproofing technology works:
Introduction of Active Chemicals: Crystalline waterproofing agents, typically in the form of a powder or liquid admixture, are introduced into the concrete mix during the mixing process.
Chemical Reaction with Moisture: The active chemicals within the crystalline waterproofing admixture react with the moisture in the concrete and the by-products of the cement hydration process.
Formation of Crystalline Structures: As a result of the chemical reaction, insoluble crystalline structures begin to form throughout the capillary pores and micro-cracks in the concrete. These crystals grow and spread, filling the voids within the concrete.
Blocking Capillaries and Pores: Over time, the crystalline formations continue to grow and interlock, reducing the size of capillary pores and blocking them completely. This process makes the concrete impermeable to water.
Self-Healing Capability: One of the unique features of crystalline waterproofing technology is its self-healing capability. If new cracks develop over time, the active chemicals can react with moisture again, promoting the growth of additional crystals to seal the cracks.
Permanent Water Tightness: The end result is a concrete structure with enhanced durability and permanent water tightness. The crystalline formations act as a barrier, preventing water penetration and protecting the concrete from the detrimental effects of water, such as corrosion of reinforcing steel.
