Bentonite Geosynthetic Clay Liner

Bentonite Geosynthetic Clay Liner

Bentonite Geosynthetic Clay Liner is a kind of geosynthetic material specially used to prevent leakage.

Constituent structure

It is made of high expansibility sodium bentonite filling between special composite geotextile and non-woven fabric by needling process.

Working principle

When encountering water, the sodium bentonite particles absorb water and expand, forming a uniform and high-density rubber waterproof layer in the pad, effectively preventing water leakage. At the same time, its expansive force can make bentonite particles fill the pores and cracks of the base layer, further enhancing the waterproof effect.

peculiarity

High compactness: sodium bentonite forms a high-density diaphragm under water pressure, has very low water permeability, and has a strong self-water retention performance.

Permanent waterproof performance: Sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, there will be no aging or corrosion phenomenon, lasting waterproof performance.

Easy construction: The construction is relatively simple and does not require heating and pasting. Just use bentonite powder and nails, washers, etc. to connect and fix. No special inspection is required after construction, and if waterproof defects are found, it is also easy to maintain, and the construction period is the shortest among existing waterproof materials.

Not affected by temperature: it will not be brittle in cold climates.

Integration with structure: Sodium bentonite has a high expansion capacity when it meets water, even if the concrete structure is shaken and settled, the bentonite in the waterproof blanket can repair cracks on the concrete surface in a certain range.

Green environmental protection: Bentonite is a natural inorganic material, harmless and non-toxic to the human body, and has no special impact on the environment.

Application field

It is widely used in artificial lake water feature, landfill, underground garage, roof garden, pool, oil depot and chemical yard, municipal engineering, subway, building underground engineering and roof reservoir seepage prevention, environmental protection and sanitation, water conservancy engineering, garden artificial lake and other seepage prevention, anti-corrosion, anti-leakage, reinforcement and other projects.
