High Strength waterproof membrane for airport runway / sidewalks / road
Product features
1. Good cohesive force: The sealant bonding strong with concrete, bricks, plastics, aluminum products, plastic products, galvanized plate and other material.
2. High strength and high elastic:Soft and high strength, Particularly suited to variant of the larger structure loop seal waterproof .
3. The weathering resistance, tear resistance, abrasion resistance, good penetration resistance.
Scope of application
1. Concrete buildings settlement joint and expansion joint, construction seam and metal structure of the seal waterproof.
2. For reservoirs, swimming pools, balcony, toilet bath rooms, through-wall pipe joint seal, etc.
3. The airport runway, sidewalks, roads, Bridges, square joint seal.
4. Prefabricated building roof panel, external wall panel, galvanized roofing sheet fracture repair, seal waterproof.
Construction process
A. joint treatment:
1. Before the construction must clean up the seams, using steel wire brush or shovel cleaning when necessary.
2. Deeper seam fill out plastic foam or hemp yarn as the backing material, the construction site must be dry.
B. Burdening: According to A component: B component = mass ratio of 1:2, pour A component into the B component ,and then use after mixture.
C. Construction operations:
1. When filling embedded horizontal seam, fill with good adhesive solution slowly in the joint gap until full.
2. Construction method of vertical fractures, when glue liquid condensed paste colloid as early, available extrusion ash knife or gun's embedded within the joint.
