The following is how to choose waterproof materials and waterproof construction should pay attention to the problems described as follows:

The new generation of waterproof materials then step to light quality, convenient construction, no pollution to the environment, durable, beautiful color direction development; Therefore, waterproof rolls are composed of paper tire felt, rubber rolls, laminated modified asphalt rolls, various synthetic polymer waterproof rolls; Waterproof coating materials from modified emulsified asphalt - plastic paste - polyurethane waterproof coating - to environmental protection synthetic polymer color waterproof coating development.

Waterproof material development to the present variety of ν, a wide variety of beautiful things in eyes, in short, the advent and application of all kinds of waterproof materials have their own advantages, or materials easy, or cost to earn, or the price is not the bottom but durable, or use different waterproof occasions; Waterproof material selection factors in addition to cost, climate, region, building function, environmental protection, the structure of the building is an important factor; If suitable for the use of waterproof coil is not suitable for the use of coating waterproof, suitable for the use of coating is not necessarily suitable for the use of coil; And such as occasions is not suitable for the use of coil waterproof: wet base, drainage is not smooth or perennial water part λ, base uneven and many prominent embedded base, back water waterproofing, water cockscomb waterproof, typhoon grade is larger and more areas; Such as the base is not suitable for coating waterproof: wood slope tile house bottom waterproof.

The disadvantages of waterproof roll are as follows: waterproof roll in waterproof construction, when the shape of the waterproof base is based on the amount of body intercepting, for the complex shape of the base needs more pieces of splicing, waterproof roll mutual bonding is difficult, because the splicing affects the beauty of the waterproof layer; Then the complete ****** sealing will become the main problem, © water hidden dangers ******, opportunities *** more is the lap of the coil λ; Then ****** time waterproof coil has decades of durability, but the domestic is still less matched with the binder, due to the environment and bonding material itself and other factors often lose bonding function in advance, resulting in waterproof failure will be self-evident; Moreover waterproofing materials in the construction of the protection and © after maintenance is also a difficult problem, after water naked ¶ outside waterproof layer to external mechanical injury prevention is very important, waterproofing and grassroots binding whether full shop, shop, shop, empty shop, water layer between coil and at the grass-roots level will be go, regardless of any department lambda perfoliate breakage, degumming, © glue (even only one), The waterproof function of the whole coherent layer will all fail, if the damaged and defective part λ can not be found, the local repair is impossible, and the o only redo the waterproof layer. For those with a concrete protective layer of waterproof layer, although the external mechanical penetration is no longer possible, but such as along the trench and other parts λ is not suitable for the protective layer; Then along the ditch and other parts λ due to the sewer blockage and other reasons of long-term water is likely to be greater, during which the watertight layer shall not have the slightest defect; So along the trench λ roll waterproof success less chance; Due to the complex shape along the ditch, the water tunnel, the water outlet and other parts of the λ sealing difficulty, the waterproof coil has also become the key technology; In addition, due to the aggregation of living and production wastewater along the ditch, the harmful components accelerate the decomposition, aging, and even failure of the coil bonding material.

To sum up, the disadvantages of coil waterproof is not equivalent to its incurable disease, we put forward and face it, find a solution to the problem; Such as high quality and durability of the binder to solve the bond strength and bond aging subject matter, patient construction to overcome the bond sealing problem, the use of multi-channel fortification and composite use of coating waterproof layer, in order to solve the problem of fear of penetration and waterproof layer reliability of the coil; It is to weigh the advantages and disadvantages really do not suit to use roll when should boldly change and coating waterproof.

Waterproof coating, waterproof coating because of its convenient construction, manufacturers, easy materials, part of the waterproof coating production equipment is relatively simple, so it is also the early development of waterproof materials, and has been used.
