Introduction:
GCL is composed of 3 layers, the upper layer is nonwoven geotextile, while the lower layer is woven geotextile, natural sodium bentonite fills the gap between geotextile layers. The application with natural sodium bentonite can extend the using life of construction. Our GCL creates a new green and environmental building material.
Features:
1. Compactness: sodium bentonite formed high density diaphragm under pressure state, when a thickness of about 3mm, its water permeability of 5 × 10-11m / s or less, equivalent to 100 times the density of 30cm thickness of clay, with a strong self-protection water performance.
2. Permanent waterproof performance: Because sodium bentonite-based natural inorganic material, even after a very long time or the surrounding environment changes, aging or corrosion will not occur, and therefore the waterproof performance is very durable.
3. The construction is simple: compared with other waterproof materials, the construction is relatively simple, does not require heating and paste. Just bentonite powder and nails, washers, etc. are connected and fixed. After construction does not require special inspection, if found defective water is also easy to repair. GCL waterproof material in existing shortest construction period material.
4. Impact from temperatures: in cold weather conditions are not brittle fracture.
5. Integration of waterproof materials and objects: sodium bentonite water, with 20 to 28-fold expansion of capacity, even if the concrete structure to vibrate and settlement, GCL bentonite can repair cracks in the concrete surface within 2mm.
6. Green: Bentonite is a natural inorganic material, no particular impact on the environment, with good environmental performance.
