MasterLife WP 3760

Crystalline Waterproofing Admixture for Concrete & Mortars

Material Description

MasterLife WP 3760 crystalline waterproofing powder admixture is an integral crystalline capillary waterproofing admixture for concrete. It is designed for use in above- and below-grade applications. MasterLife WP 3760 consists of Portland cement, very fine treated silica sand and various active, proprietary chemicals. These active chemicals react with the moisture in fresh concrete with the byproducts of cement hydration to cause a reaction,
which generates an insoluble crystalline deposit throughout the pores and capillary tracts of the concrete. Thus the concrete with MasterLife WP 3760 reduces water permeability. This product also has a selfhealing property under presence of moisture and can heal cracks below 0.4 mm.

Areas of Application

MasterLife WP 3760 should be used in all structural concrete that is constantly or intermittently in contact with water such as sea walls, tunnels, basements, structural and precast concrete. MasterLife WP 3760 can also be used as crystalline waterproofing admixture for cement mortars and plasters. To waterproof structures such as:

• Building Basement and foundations

• Sewage and water treatment plants

• Dams, canals, Tunnels, Harbours

• Tunnel and subway systems

• Water reservoirs

• Concrete pipes

• Parking structures

• Pre-Cast, Cast-in-Place and Shotcrete applications

• Swimming pools

• Retaining walls & sea defense wallsCharacteristics and Benefits

MasterLife WP 3760 offers the following benefits:

• Crystalline cementitious material

• Integral addition

• Reduces concrete permeability

• Allows concrete to breathe

• Non toxic

• Becomes an integral part of the concrete.

• Reduces penetration of water and other liquids

• Can seal hairline cracks up to 0.4 mm.

• Resists positive and negative side hydrostatic pressure

• Protects against sewage and industrial wastes

• Less expensive than traditional methods

• Added to the concrete at time of batching and therefore is not subject to climatic restraints
