When mixed with water and applied as a cementitious coating, the active chemicals in XYPEX cause a catalytic reaction which generates a non- soluble crystalline formation of denritic fibers within the pores and capillary tracts of concrete. The concrete itself becomes permanently sealed against the penetration of water or liquids from any direction. Advantages over other types of waterproofing is that this product can waterproof underground structures from the inside against hydrostatic pressure. By the process of osmosis and because the chemicals in XYPEX have an affinity with water, the crystalline formation migrates throughout the pores and capillary tracts of concrete even against strong hydrostatic pressure. Application : XYPEX is a unique chemical treatment for the waterproofing and protection of concrete. Among its many uses, is suitable for waterproofing reservoirs, sewage and water treatment tanks, tunnels, manholes, underground vaults, foundation walls and parking decks. It can be used on either poured in place concrete or concrete block and can be applied to either the interior or exterior surface with equal results. Applicable Standards: Approved by the National Sanitation Foundation (NSF) for potable water. Coverage : One coat should have a thickness of just under 1/16" when a second coat is required it should be applied after the first coat has reached in initial set but is still "green". For normal surface applications coverage per coat is 1.5 lbs. per sq. yd. Specifications : At 72° F Compressive Strength (ASTM D-695): 3 days 2,900 psi 28 days 5,100 psi Bond Strength (ASTM C-882): 28 days 820 psi (hardened concrete to hardened concrete) Tensile Strength (ASTM D-638): 28 days 770 psi Vapor Permeability (ASTM E-96): 28 days 0.075 perms Application Life: 30 min Recoat Time: 8–24 hrs Final Cure: 14 days Description : A curing agent designed specifically for Xypex crystalline waterproofing products. The use of Gamma Cure may eliminate the need for water curing the Xypex coating in some cases. Consult manufacturer for specific recommendations. K-11 Hey'Di Description : A breathable, two part, polymer modified, cement based system for waterproofing concrete and masonry. Has a texture and consistency similar to concrete and may be brush or spray applied. Becomes an integral part of the wall and waterproofs the negative or positive side through a crystallization process. Hey'Di K-SB is the bonding agent used with Hey'Di K-11. It improves adhesion, flexibility and the permeability resistance of the system. Application : Apply to above or below grade surfaces (interior or exterior) to protect against hydrostatic water pressure. Typical applications include foundations, basements, tunnels, dams, water reservoirs, manholes, sewage and water treatment plants, and any other underground structures. Effectively waterproofs concrete, medium/heavy weight concrete block, brick and shotcrete. Applicable Standards : Approved by NSF (ANSI STD 60/61) for use with potable water. It is also approved by the USDA for food plants. Coverage : One 50 lb. bag covers approximately 200 ft²/coat. 2 coats recommended. Positive side waterproofing, blend 1½ qts. SB concentrate with required mix water. Negative side waterproofing, blend 2 qts. SB concentrate with required mix water. Specifications : At 72° F Application Life: 30 min Recoat Time: 24 hrs Final Cure: 7 days No. Size TAM K11 50 lb. bag, Gray, 48/pallet Liquid: TAM 1GSB 1 gal. pail, 4/ctn, 48 lbs.
