APP Modified Asphalt Waterproof Membrane (JC/T974, JC/T536)

Brief Introduction:
1. "Yuhong" APP Modified Asphalt Waterproof Membrane
2. Dipping and covering material: amorphous polypropylene (APP) modified asphalt
3. Upper surface coating: PE film, fine sand, mineral granules or aluminum foil, copper foil or other isolating materials
4. A kind of windable sheet waterproof material

Applications of APP Modified Asphalt Waterproof Membrane:
1. Waterproofing for all kinds of building roof engineering projects: treading and non-treading surfaces, heat preservation and non-heat preservation surfaces, planting building surfaces, roof parking lots, and converted building surfaces
2. Waterproofing for such municipal engineering projects as bridge surfaces of subways, tunnels, concrete roads, sewage treatment, garbage burying projects and other
3. Waterproof or damp proof purpose for all kinds of underground projects, indoor swimming pool, etc.
4. Waterproofing for penstocks, swimming pools, water pools, and other water conservancy projects
