Kryton Krystol T1 Negative Water Pressure Crystallising Penetrating Waterproofing Coating

Krystol T1 is a cementitious crystallising waterproofing coating suitable for interior and exterior surfaces of new and existing concrete structures. Supplied as dry powder, it forms a coating when mixed with water for easy application. It reacts with unhydrated cement particles in concrete to generate masses of needle-shaped crystals that penetrate deep into the concrete, filling pores and micro-cracks. This process continues for weeks to months, forming a permanent waterproofing barrier. Even if later shrinkage or settlement creates cracks (≤ 0.5 mm), the crystallisation process reactivates on contact with water for self-healing.
