Because sodium base bentonite is a natural inorganic material, even after a long time or the surrounding environment changes, also won't happen aging or corrosion phenomena, so the waterproof performance persistence.
Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, its permeability is 5 x 10-11 m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay, have very strong since the water retention performance.
Not affected by temperature, In cold climates will not brittle fracture.
Bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, have good environmental performance.
(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.
