What are the advantages and disadvantages of waterproofing membrane?
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, jerry, a uniform layer thickness, the base layer can effectively overcome stress empty shop (the base layer occurs at the time maintaining the overall efficiency of large cracks waterproof layer).
There are many types of waterproofing membrane, mostly flexible waterproofing membrane. Such as: SBS coil, PVC, EVA, ECB
The advantages of the coil is simple operation, do not need any valuable equipment, the basic is the torch, hot melt welding machine, are not expensive, the shortcomings of the base is a higher demand, it is easy to be damaged, resulting in structural leakage.
The waterproof membrane study its drawbacks: waterproofing is performed when the amount of coating material according to the cross-sectional shape of the waterproof base waterproof construction, the need for a complex shape of the base layer a plurality of splicing, waterproofing overlap each other at the bonding difficult than Large, due to the impact of multi-block splicing waterproof layer of beauty; then completely absolute seal 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 a few decades durable for a long time, but the country is still less matched the binder, and the binder material itself due to environmental factors such as loss of adhesion is often ahead of function, thus leading to the failure of the waterproof self-evident; Furthermore Waterproof membrane after the construction of the protection and leakage after the maintenance is also a problem, exposed waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and the grass-roots bonding, whether full of shops, shop, shop air, between the base layer and the web would be to go aqueous layer, regardless of any part of the cross-cutting breakage, degumming, drooling (even the only one), the entire coherent thereto waterproof power level Will lose all bad, if you can not find damaged and defective parts, the local repair is not possible, then only redo waterproof layer.
