Product Description

Bentonite waterproof blanket

Swelling waterproof blanket is a kind of geosynthetics specially used for artificial lake water features, landfill, underground garage, roof garden, pool, oil depot and chemical yard, which is made of highly inflatable Sodium bentonite filled in a special composite geotextile and non-woven fabrics, made by acupuncture method of bentonite anti-pad can form many small fiber space, the bentonite particles can not flow in one direction, when the water in the pad The formation of uniform high-density gel-like waterproof layer, effectively prevent water leakage.

Waterproof features


Sodium bentonite in the water pressure to form a high-density diaphragm, the thickness of about 3mm, its permeability is & × 10 ~ 11m / sec or less, equivalent to 100 times the thickness of 30cm thick clay, with a strong self-retaining properties The

Has a permanent waterproof performance

Because sodium-based bentonite-based natural inorganic materials, even after a long period of time or the surrounding environment changes, there will be no aging or corrosion phenomenon, so waterproof performance lasting.

Short construction period is short

Compared with other waterproof materials, the construction is relatively simple, do not need to heat and paste. Simply use bentonite powder and nails, washers, etc. to connect and fix. After the construction does not require special inspection, if found to be easy to repair water shortages. GCL is the shortest construction period in existing waterproof materials.

Not affected by temperature

In the cold weather conditions will not brittle.


Waterproof material and the integration of objects: sodium bentonite with water, with 20-28 times the expansion capacity, even if the concrete structure vibration and settlement, GCL bentonite can also repair within 2mm concrete surface cracks.


Bentonite is a natural inorganic material, harmless to human body, no special impact on the environment, with good environmental performance.

Technical indicators

GCL longitudinal elongation at break (%) ≥10;

GCL transverse elongation at break (%) ≥10;

GCL vertical permeability coefficient (cm / s) ≤ 5 × 10-11;

GCL peel strength (N / 100mm) ≥ 40; GCL anti-hydrostatic test 0.4MPa, 1h, no leakage.0.4

Bentonite composite waterproof mat (GCL) construction precautions

1, bentonite composite waterproof mat (GCL) storage and transportation should be waterproof, moisture, anti-strong sun sun exposure. Storage should be taken on the ground when the overhead method, transported to the scene of the bentonite composite waterproof pad (GCL) should be used in the day.

2, in the next process or adjacent construction, should have completed the process of bentonite composite waterproof pad (GCL) properly protected, no manned damage.

3, should try to avoid wearing spikes, high heels in the bentonite composite waterproof mat (GCL) on the stampede; vehicles and other machinery shall not be rolled bentonite composite waterproof mat (GCL).

4, in the GM / GCL composite liner construction, has been completed by the GCL HDPE film should be completed in the day of construction or laying 300mm thick clay layer, the day can not complete the HDPE film or clay protective layer construction, should cover GCL , To prevent the rain and make the GCL first hydration and strong sun on the GCL sun exposure.

5, the GCL single-layer liner anti-seepage, waterproof construction works, after the end of the construction and acceptance, should quickly use the proportion of more than 2.0 soil, sand or stone backfill. Backfill to prevent the GCL damage, backfill can not contain more than 10mm diameter gravel, backfill thickness should not be less than 30cm. Backfill should be graded backfill compaction, compaction degree can not be less than 85%.
