GCL bentonite waterproof blanket-GCL膨润土防水毯

characteristic

1. Compactness: Sodium based bentonite forms a high-density diaphragm under water pressure, with a permeability of 5 when the thickness is about 3mm × ten ˉ Below 11m/s, equivalent to 100 times the density of 30cm thick clay, it has strong self water retention performance.

2. Waterproof performance: Because sodium based bentonite is an inorganic material, even after a long period of time or changes in the surrounding environment, it is not prone to aging or corrosion, resulting in long-lasting waterproof performance.

3. Easy construction: Compared with other waterproof materials, the construction is relatively simple and does not require heating or pasting. Simply use bentonite powder, nails, washers, etc. for connection and fixation. After construction, there is no need for special inspection, and if waterproof defects are found, they are also easy to repair. GCL is one of the existing waterproof materials with a short construction period.

4. Not affected by temperature: It will not brittle even in cold weather conditions.

5. Integration of waterproof materials and objects: When sodium based bentonite encounters water, it has a swelling capacity of 20-28 times. Even if the concrete structure undergoes vibration and settlement, the bentonite in GCL can repair cracks on the concrete surface within 2mm.

6. Bentonite is an inorganic material that has no special impact on the environment and has good performance.
