Bentonite waterproof blanket is a building material used for waterproofing, mainly made of bentonite (swelling clay), a natural clay mineral with excellent water absorption and swelling properties.
Bentonite waterproof blanket is a building material used for waterproofing, mainly made of bentonite (swelling clay), a natural clay mineral with excellent water absorption and swelling properties. Bentonite waterproof blankets usually consist of the following parts:
Bentonite layer: This is the main component of the waterproof blanket. Bentonite will swell after absorbing water, thus forming an effective waterproof barrier. This layer is usually sandwiched between two layers of cloth to enhance the stability of the structure.
Protective layer: On the outside of the bentonite layer, there is usually one or more layers of protective cloth, which are usually made of polyester cloth, fiberglass cloth or other synthetic fibers. The protective layer can prevent the bentonite layer from being damaged during construction and provide additional mechanical strength.
Adhesive layer: Some bentonite waterproof blankets are also designed to include a layer for bonding to the substrate, which can ensure the stability and effectiveness of the waterproof blanket during use.
The advantages of bentonite waterproof blankets include:
Excellent waterproof performance: Bentonite will swell when it comes into contact with water, effectively preventing water penetration.
Strong adaptability: It can adapt to slight movement or settlement of the foundation and is not prone to cracks.
Long-term stability: Bentonite has high chemical stability and durability, and can maintain its waterproof performance for a long time.
This material is usually used for waterproofing of underground structures (such as basements, tunnels, foundations, etc.), and can also be used for waterproofing needs in some special environments. During installation, the waterproof blanket usually needs to be fully bonded to the base and ensure the sealing of the joints to ensure the overall waterproof effect.
