Bentonite waterproof blanket (GCL)
Bentonite composite waterproof material

Mainly composed of bentonite and other materials, it has many advantages:

Excellent waterproof performance: It can effectively prevent moisture infiltration and form a durable and reliable waterproof layer.

Strong adaptability: able to adapt to different terrains and grassroots conditions.

Self repair ability: Small cracks and damages can automatically repair when exposed to water.

This material is commonly used in the following scenarios:

Underground building waterproofing: such as basements, underground parking lots, etc.

Tunnel engineering: ensuring the dryness and structural safety inside the tunnel.

For example, in the construction of a large commercial basement, the use of bentonite composite waterproof materials can ensure that the basement is not invaded by groundwater even under complex geological conditions; In tunnel construction, the use of this material can effectively prevent leakage of tunnel walls and reduce the impact on tunnel structure and functionality.

FREQUENTLY ASKED QUESTIONS

What material is bentonite waterproof blanket made of?

Bentonite waterproof blanket is mainly composed of natural sodium-based bentonite particles, geotextiles and geomembranes.

What is its waterproof principle?

Bentonite swells when it meets water to form a uniform colloidal waterproof layer, which can effectively prevent water penetration.

What projects is it suitable for?

It is suitable for various waterproof projects such as landfills, artificial lakes, basements, tunnels, and water conservancy projects.

How long is the service life of bentonite waterproof blanket?

Under normal use and maintenance, it can generally reach several decades. However, the specific life span will be affected by environmental conditions, construction quality and other factors.
