Recommended combination of artificial lake anti-seepage - composite geomembrane + bentonite waterproof blanket

The artificial lake has a complex structure and different shapes. Generally, there are curved river channels, protruding bridge piers, artificial islands of different shapes, irregular rubble retaining walls, different landscape revetments, and landscape garden seepage prevention, such as rigid waterproofing, may cause problems. Due to the uneven settlement of the foundation, cracking and leakage are caused, and the best anti-seepage effect cannot be achieved, and the cost is high and the construction period is long. So how to solve the leakage problem of landscape lake or artificial lake? Composite geomembrane and bentonite waterproof blanket is the best combination!

Composite geomembrane

Composite geomembrane is an impermeable material composed of geotextile and geomembrane. It is mainly used for anti-seepage. The composite geomembrane is divided into one cloth and one membrane and two cloths and one membrane. 1500g/m2, with high physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting, which can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, tunnel, etc. Because of its selection of polymer materials and the addition of added materials in the production process Anti-aging agent, so it can be used in unconventional temperature environment.


Bentonite waterproof blanket is a new type of composite anti-seepage material. Bentonite has good adhesion and expansion. The internal structure is a layer of non-woven fabrics on the upper and lower sides. After absorbing water, it expands in a limited space to form a tight colloid, thereby achieving water-stopping. Effect. Because of its excellent characteristics, it has also been listed as the first choice for ecological pool waterproof materials. The material is a blanket waterproof membrane made by mixing graded natural sodium-based bentonite particles and corresponding additives as raw materials, and fixing the bentonite particles between geotextiles and plastic woven fabrics through acupuncture technology and equipment. . Bentonite waterproof blanket not only has all the characteristics of geotextile, but also has excellent waterproof (permeability) performance. The mineralogical name of bentonite is montmorillonite, and natural bentonite is mainly divided into two categories: sodium-based and calcium-based according to its chemical composition. Bentonite has the property of swelling with water. When calcium-based bentonite swells, its swelling is only about 3 times its own volume, while sodium-based bentonite absorbs water five times its own weight when it meets water, and swells to more than 15-17 times its original size. The sodium bentonite is locked in the middle of two layers of geosynthetics, which plays the role of protection and reinforcement, so that GCL has a certain overall shear strength.The bentonite particles expand with water to form a uniform colloidal system. Under the restriction of two layers of geotextile, the bentonite expands from disorder to order. The result of continuous water absorption and expansion is to make the bentonite layer dense, so it has the function of waterproof.
