APP selection of asphalt waterproofing membrane selection points
5, membrane and coating composite use should be compatible, and should be placed on top of the coating; coil and waterproof mortar composite use should be placed under the waterproof mortar.
4, glass fiber reinforced polyester felt coil can be used for mechanical fixed single layer waterproof, but through the wind load test.
3, Ⅱ type fiberglass fetal APP modified asphalt waterproofing membrane tension is higher, dimensional stability and heat resistance, good, but no elongation. Suitable for general and relatively cold areas and stable structure of the general engineering roof or underground waterproofing works.
2, Ⅱ type polyester tire modified PET asphalt waterproofing membrane, with a large pull, high elongation, heat resistance and good low temperature flexibility and so on. Applicable to the general and relatively cold or more hot areas, waterproof level for the I, Ⅱ, Ⅲ level roof waterproofing works.
1, I type polyester tire or glass fiber tire modified asphalt waterproofing membrane PET higher heat resistance, but low temperature flexibility is poor. Suitable for non-cold areas for general construction works of the roof waterproof layer. The waterproofing material of the upper surface material of polyethylene film or fine sand shall not be exposed.
