Roof waterproofing coatings are now mostly used liquid membrane, is why?

Waterproof material development to today, the name of a variety of, is categorized as flexible waterproof material attached to the waterproof base layer of the form, roughly divided into two categories. That is, membrane waterproofing and paint waterproofing. So, why on earth would you want to use a liquid volume instead of a traditional coil for roof waterproofing? Let's look at it together!

The original traditional waterproofing membrane should be considered as paper, tires, linoleum, with linoleum for waterproofing must be bonded with construction asphalt and laid on the upper seat. Usually do three linoleum or private three felt. This practice is labor-intensive and the construction technique is difficult to master. Preparation of asphalt, a large amount of exhaust on the environment is seriously polluted, can not be used where the fire can not be constructed, prone to fire and burn accidents, the roof of the second repair difficulties

Traditional membrane drawbacks

Construction difficulty: traditional waterproofing ring in waterproofing project to be based on waterproofing grass-roots level of the shape of the cut and split installation, for the complex shape of the grass-roots level requires more than one joint, waterproofing ring overlap each other where the adhesive More difficult. Because multiple joints will affect the aesthetic of the waterproof layer. In addition, completely absolute sealing will become the main problem, the greatest risk of leakage, the most opportunity is the overlapping parts of the roll. In addition, high-grade waterproofing membranes have a durability of decades, but there are still almost no adhesives in the country that are compatible with them. Due to factors such as the environment and the bonding material itself, the bonding function is often lost early, not to mention waterproofing failure.

Maintenance difficulty: once again, waterproofing ring after construction protection and repair after leakage is also a difficult problem, the exposed waterproof layer of external mechanical damage prevention is very important. Waterproof circle and the adhesion of the grass-roots level will be in the 10,000 steps, stores, packaging, terror, rolls and grass-roots level between all become water exchange. Certain parts of the penetrating damage, debonding, water leakage.

Difficult to seal along the trench. For the waterproof layer with a concrete protective layer, external mechanical penetration is no longer feasible, but the ditch and other parts are not suitable for making a protective layer. In addition, the ditch and other parts of the high probability of long-term accumulation of water due to clogged sewers and other reasons, previously waterproof layer of watertightness should be no defects. Therefore, it is highly unlikely that the coil waterproofing along the ditch will be successful. Coil waterproofing has also become technically critical due to the complex shape of the ditch and the difficulty of sealing water holes, drains, and other parts of the ditch. In addition, due to the coalescence of domestic and production wastewater in the ditch, harmful components will accelerate the decomposition, aging, and even effectiveness of the coil bonding material.

[Liquid coil characteristics]

1. Low-carbon environmental protection, environmental protection and flame retardant, non-toxic and non-polluting;

2. The same construction method as waterproof coating, construction is simple and convenient, low cost.

3. Closely linked to the foundation, heat insulation and waterproofing project integration;

4. Can be constructed on a damp foundation, the environment has no special needs, construction is convenient, easy maintenance afterwards.

5. Elasticity, cracks, anti-freeze, low temperature still have good elasticity.

6. Very strong adhesion, anti-aging, elasticity, more suitable for the structure is easy to break the deformation part of the waterproofing.

7. Strong self-repairing ability, can repair perforated holes, waterproofing quality is guaranteed.

8. It has excellent water resistance and sunscreen effect, -50 ~ 88 can be used, the life of up to 20 years, can reduce the roof temperature, is the best umbrella for the building roof.
