MITCHSEAL CWP

Crystalline Capillary Waterproofing

MitchSeal CWP is a cementitious capillary waterproofing system, which provides a permanent solution to leakage, seepage or ingress of water in concrete by sealing capillaries and shrinkage cracks in both positive and negative side of the structure. MitchSeal CWP penetrates into pores of substrate by capillary action and is carried deep into concrete by inherent moisture therein. MitchSeal CWP is activated by moisture and reacts with free lime present in cement matrix and creates a continuous barrier of insoluble crystals. The capillaries are permanently blocked to the passage of water. Rate and penetration of crystals depends on presence of moisture, free lime and density of concrete.

MitchSeal CWP is ideal for

• Waterproofing of roofs
• Retaining walls
• Basements
• Water tanks and other water retaining structures
• Swimming pools
• Reservoirs
• Bathrooms
• Tunnels
• Machine pits
• Concrete walls
• Concrete pipes
• Canals
• Dams
• Elevator pits
• Sea walls
• Planters and any other concrete structures requiring protection from water ingress.

Simple mixing and application It is a permanent waterproofing solution as it becomes an integral part of the concrete structures instead of merely being a surface coating or membrane that can be damaged or delaminated. Equally effective for both positive and negative side waterproofing. Will be re-activated upon contact with water thereby providing lifetime protection. Prevents corrosion of steel reinforcement. Does not require special protection during back filling etc.
