​​​​MasterSeal 501/502 - A surface applied capillary waterproofing system for concrete and block work

How does MasterSe​​al 501/502 work?

The MasterSeal 501/502 waterproofing system ensures a total and permanent solution to water leakage, ingress, or seepage in concrete structures or any cementitious substrate. The formation and development of insoluble crystals into water bearin​​g capillaries and interstices effectively blocks the further passage of water.

Where is MasterSea​​l 501/502 used?

MasterSeal 501/502 can be used to help the retention of water in storage, treatment, and transportation units. Applications include: 

• ​Water tanks and reservoirs
• Building basements and foundations
• Swimming pools and water parks
• Sewage and water treatment plants
• Dams, canals, tunnels and harbours
• Retaining walls and sea defence walls
• Concrete pipes 
  

What are the benefits of ​​MasterSeal 501/502?

MasterSeal 501/502 is a versatile product offering many advantages to the user:

• Provides total and permanent waterproofing properties by becoming an integral part of the structure to which it is applied. Active ingredients will not delaminate, peel off or wear away
• Protects concrete and reinforcement against corrosive waterborne substances
• Crystalline action is reactivated by contact with water providing permanent and continuous protection
• Effective against both positive and negative water pressure
