Product Description
Product Introduction
GCL are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibersfrom the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).when hydrated under a confining load,the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compactd clay.

Product Feature
(1) A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up to 1.0MPa above, permeability coefficient 5 *10-9cm / s.
(2) Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction.
(3) Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.
(4)green: Bentonite is a natural inorganic material, harmless, non-toxic,no particular impact on the environment, with good environmental performance.
(5) simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste.
(6) Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.
Product Application Range
(1)Municipal engineering, underground engineering subways, buildings and roofs reservoir seepage.
(2)Environmental sanitation, solid waste landfills, sewage treatment plants, industrial waste.
(3)water, rivers, lakes and reservoirs dam seepage, plugging, reinforcement.
(4)Garden artificial lake golf course pond seepage and so on.
(5)Petrochemical, mining and other areas of engineering seepage, leakage, etc
