Product Description:

1.Structure of Bentonite Waterproof Blanket Description:

Bentonite composite waterproof blanket (GCL) is a new type of geosynthetic materials. It is mixed by a natural grading sodium base bentonite particles and corresponding admixture. And by the special technology and equipment, it is fixed between the two layers of geotextile bentonite particles, made from bentonite waterproof blanket.It not only has all the characteristics of geotechnical material, but also has excellent waterproof performance (permeability).

2.Main Features of Bentonite Waterproof Blanket:

•Excellent waterproof performance.

Having all properties of geotextile material, such as separation, reinforcement and protection, filter, etc.

Easy for construction 

No affected by the limitation of the environment temperature, even under 0 ℃ can be construction too.

The cost performance is relatively high.

Being used in very wide range.

Q:The difference between waterproof linoleum and waterproofing membrane
`Linoleum is a kind of waterproofing membrane! Belong to subordinate relationship. Felt is made of animal hair or plant fiber made of carpets or thick paper impregnated asphalt after the building materials, toughness, impermeable, used to do the roof, basement walls, foundations such as waterproof, moisture-proof layer. Also called oil felt. Approximately 2000 years ago, the most commonly used building waterproof material, has now been included in the scope of national banned building materials. At present, the construction of waterproofing membrane is large "elastomer modified asphalt waterproofing membrane" - the implementation of standards for the GB 18242-2008.
Q:How to choose waterproof membrane
First, pay attention to product name and packaging logo According to the product standard, the product packaging should indicate the name of the enterprise, product mark, production date or batch number, production license number, storage and transportation precautions, for the product mark should be strictly in accordance with the standard, consistent with the product name, Incomplete or unmarked. Users in the choice of these products, we must pay attention to product mark, recognize the product name, because the mark represents the identity of the product. Example: With polyester-cotton non-woven fabric - mesh cloth composite tire production of the coil, can only be named asphalt composite tire flexible waterproof membrane or composite tire coil, and can not name SBS coil, its product mark Can only be marked by compound tires.
Q:Asphalt waterproofing membrane and polymer waterproofing membrane
One of the elastic modified asphalt waterproofing membrane on behalf of the product is SBS modified asphalt waterproofing membrane; plastic modified asphalt waterproofing membrane on behalf of the product is APP modified asphalt waterproofing membrane.
Q:What kind of waterproofing membrane, waterproofing membrane is how to classify their respective advantages?
TPO waterproofing membrane: strictly speaking TPO waterproofing membrane is EPDM (EPDM) and PVC combination, most of the performance are lower than EPDM.
Q:How to use self-adhesive waterproofing membrane?
1) grass-roots treatment: grass-roots surface should be treated first, so that the grass-roots solid, clean, and fully moist, no water. 2) wiping cement (waterproof) mortar: its thickness is generally 10 mm ~ 20 mm (depending on the level of formation may be), paving should pay attention to compaction, smoothing. In the corner, should be wiped into a radius of 50mm or more fillet. Paving the thickness of cement mortar than the length of the coil, short side should be wide out of 100 ~ 300mm, and in the process of spreading the use of rail to ensure smoothness. 3) peel off the self-adhesive waterproof membrane under the surface of the isolation film.
Q:Modified asphalt waterproofing membrane SBS I G PE4 What does it mean?
Waterproof membrane is mainly used for building walls, roofs, as well as tunnels, highways, landfills, etc., to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials, as the basis for engineering And no leakage between the building connection, the entire project is the first waterproof barrier, the entire project plays a vital role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane
Q:What is the accounting subject of the waterproofing membrane
For external construction, included in the construction Self-service maintenance, included in the manufacturing costs (management costs)
Q:How is the water level rated and how many grades are used?
Roof waterproofing level, mainly the ability of roof waterproofing, to distinguish between the various levels, generally based on the construction process and the choice of waterproof material. Waterproof at all levels of specific materials do not have clear requirements, as long as the water resistance and service life can be achieved.
Q:Do you know how many square meters of waterproofing membrane to send a set of tests?
Modified asphalt polyethylene tire waterproofing membrane: any volume in the distance 2m at the end of the interception of 1m full-width coil sample 2, 1000 volumes for a group, the lack of a group also
Q:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
BAC is not equal to PET, carcass material is not the same, and BAC also fiberglass tire coil.
