Bentonite waterproof blanket for landfill site-垃圾填埋场膨润土防水毯

Product Introduction:

Bentonite waterproof blanket is a geosynthetic material used for preventing leakage in artificial lake waterscapes, garbage landfills, underground garages, rooftop gardens, water pools, and chemical storage yards in oil depots. It is filled with high expansion sodium based bentonite between specially made composite geotextiles and non-woven fabrics. The bentonite anti-seepage pad made by needle punching can form many small fiber spaces, preventing bentonite particles from flowing in one direction, When encountering water, a uniform high-density adhesive waterproof layer is formed inside the pad, effectively preventing water leakage. Bentonite waterproof blankets can be divided into needle punched sodium based bentonite waterproof blankets, needle punched membrane coated sodium based bentonite waterproof blankets, and adhesive bonded sodium based bentonite waterproof blankets according to production processes. The needle punched membrane covering method sodium based bentonite waterproof blanket is a composite layer of high-density polyethylene geotextile on the outer surface of the nonwoven geotextile of the needle punched sodium based bentonite waterproof blanket.

Performance characteristics:

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

Due to its waterproof performance, sodium based bentonite based inorganic materials will not age or corrode even after a long time or changes in the surrounding environment, resulting in long-lasting waterproof performance.

Simple construction and short construction period - Compared with other waterproof materials, construction is relatively simple and does not require heating and 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.

Not affected by temperature - not brittle even in cold weather conditions.

Integration - Integration of waterproof materials and objects: Sodium based bentonite has 20-28 times the expansion capacity when encountering water. Even if the concrete structure undergoes vibration and settlement, the bentonite in GCL can repair cracks on the concrete surface within 2mm.

——Bentonite is an inorganic material that is harmless to the human body and has no special impact on the environment. It has good properties.

High performance to price ratio, widely used. The product range can reach 6 meters, greatly improving construction efficiency.

Scope of application: Applicable to municipal (landfill), water conservancy, and artificial lake building underground waterproofing and anti-seepage engineering.

Construction can still be carried out at negative temperatures (-20 ℃) where traditional waterproof materials cannot be applied; Construction can also be carried out on damp base layers (without open water); Construction cannot be carried out in rainy and snowy weather; Not suitable for strong acid or alkaline solution anti-seepage; Due to the inorganic nature of bentonite, its durability is better than that of organic waterproof materials.
