N E T SLAB/HORIZONTAL EXPANSION JOINT Self Expanding Cork Molded of selected cork granules and resin binders then specifically treated to permit expansion of as much as 50% of original thickness. The material is non-extruding and used where excessive contraction is anticipated. Because of its mechanical sealing properties, it is particularly suited for joints in liquid-containing structures, (in conjunction with waterstops and/or sealants) or for preventing intrusion of foreign matter into overly contracted joints. Elastomeric, chemically- cured sealants are recommended for use with this product. Weight at 1/2" thickness is 1.2 lbs per sf. Conforms to: ASTM D 1752 Type III AASHTO M 153 Type III HHF 341F Type II, Class C CRDC509 Type III FAA P610-2.7 Cork Preformed from selected cork particles and bonded together with an insoluble resin. This joint filler is resistant to acids and alkalies, is flexible, waterproof and light in color. It will not extrude when compressed to 50% of its original thickness and will recover to approximately 95% when released. Cork expansion joint is compatible with elastomeric, chemically cured sealant. Applications include water and sewage treatment plants, flood walls, outlet works, spillways and industrial construction. Weight at 1/2" thickness is .75 lbs per sf. Conforms to: ASTM D 1752, Type II CRD C509, Type ll HHF 341F, Type II, Class B FAA P610-2.7 AASHTO M 153 Type II Sponge Rubber Neoprene sponge rubber is resilient and compressible. It will compress without extruding and recover to 90% of its original thickness. It is compatible with all chemically-cured elastomeric sealants and can be used as an alternate to cork (meets all test requirements). Ideal for use in water and sewage treatment plants, flood walls, outlet works, spillways, bridges, commercial and industrial construction. Weight at 1/2" thickness is 1.36 lbs per sf. Conforms to: FAA P610-2.7 ASTM D 1752 Type 1 HHF 341F Type II,Class A CRD-C 509 Type 1 AASHTO M 153 Type 1
