The shortcomings of polypropylene waterproofing, and the shortcomings of modified asphalt waterproofing membrane
but the current domestic Still less match with the binder, because the environment and bonding materials and other factors often lose their bond function in advance, resulting in water failure will be self-evident; then waterproofing membrane after the construction of the protection And the leak after the maintenance is also a problem, exposed to the outside of the waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and grass-roots bonding, whether it is full shop, shop, shop, empty shop, The grassroots will be between the water layer, regardless of any part of the penetrating breakage, degumming, leakage of glue (even if there is only one), the entire level of its connection with the waterproof function will all decline, if not Find damaged and defective parts, the local repair is not possible, then only redo waterproof layer.
So it is better to waterproof polypropylene
Waterproofing membrane in the waterproof construction in accordance with the shape of the waterproof base of the bulk of the truncated, for the complex shape of the grassroots need to multi-block splicing, waterproofing membrane overlap at each other more difficult, due to the impact of multi-block splicing waterproof Layer of beauty; then completely completely sealed will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with decades of durable durability,
The advantages of the membrane waterproof, such as: the construction is convenient, the construction period is short, not need to be cured after forming, is not affected by the temperature, the environmental pollution is small, the layer thickness is easy to hold and hold the fortification meter, the material is calculated accurately, the site management is convenient, Cut corners, even thick layer, empty shop can effectively overcome the grass-roots stress (effective in the grass-roots cracks to maintain the overall waterproof layer).
