Why is waterproof blanket will "breathe" it? Why is waterproof blanket will "breathe" it? Some likened the GCL will "breathe" waterproof material, then why there is such a point? GCL is used mainly for underground water, including artificial lakes, ground transportation, etc. roadbed, the reason that it will "breathe" practical geotechnical waterproof blanket, waterproof blanket inside because sodium bentonite can play an up and down, "breathable" effect customized geotextile waterproof blanket, in the face of the water-absorbent it will become inflated role played waterproof. But it also is not a leak, and it can be "breathable" geotextile waterproof blanket, geotextile microleakage actually waterproof blanket factory, but it is negligible. Because GCL itself has to "breathe" role, to be able to make a lot of water and soil engineering to achieve waterproof effect. GCL price of the product provides technical indicators: No. Item Unit test and inspection requirements for a quality bentonite expansion coefficient ml / 2g ≥24 2 GCL unit area g / m2 ≥5000 3 GCL longitudinal fracture strength KN / m ≥10 4 GCL transverse rupture strength KN / m ≥10 5 GCL longitudinal elongation at break% ≥10 6 GCL transverse elongation at break% ≥6 7 GCL vertical permeability coefficient cm / s ≤5 × 10-9 8 GCL anti-puncture strength N ≥400 9 GCL peel strength N / 10cm ≥65 10 GCL anti hydrostatic test 0.3MPa 30min no leakage waterproof blanket and objects integrated by the majority of consumers: sodium bentonite water, with 20-28 times expansion capabilities, even if the concrete structure to vibrate and settlement, GCL bentonite can repair the concrete surface cracks within 2mm. Practical geotechnical waterproof blanket, waterproof blanket Tai'an geotechnical, Edison new materials and new materials provided by the Edison Company. Edison New Materials Co., Ltd.
