MasterSeal 501

MasterSeal 501 is a cement-based, capillary crystalline waterproofing material applied against surface waters in old and new structures from both negative and positive directions. It forms insoluble crystals within the concrete's capillaries, effectively blocking water passage while allowing vapor transmission. It's a key component of Master Builders Solutions' crystalline capillary waterproofing system.
- Provides total and permanent waterproofing by becoming an integral part of the structure.
- Active ingredients do not delaminate, peel off, or wear away.
- Protects concrete and reinforcement against corrosive water-borne substances.
- Crystalline action is reactivated by contact with water, providing dormant additional protection.
- Non-toxic and non-tainting, suitable for use in potable water systems.
- Effective against both positive and negative water pressure, as well as osmotic pressure.
- Easy to prepare and apply by brush or as a dry shake.
- Water vapor permeable, allowing the structure to breathe.
