MasterSeal® 501WA is a corrosion free concrete waterproofing admixture which reacts with the hydration products of cement to form crystals within the pores and capillaries of concrete structures, thereby effectively blocking the passage of water.
Provides total and permanent waterproofing properties.
Protects concrete and reinforcement against corrosive waterborne substances.
Crystalline action is reactivated by contact with water providing dormant additional protection.
Effective against both positive and negative pressure.
Non-toxic or tainting.
Application
Used in treatment of concrete and concrete products to protect against water intrusion, leakage, cracking, chemical attack and corrosion of reinforcing steel.
Dosage
MasterSeal® 501WA is a dry powder which is added to the concrete at the batch plant at the rate of 1.5% of total cementious content up to a maximum of 6 kg per cubic metre of concrete.
