Bentonite waterproof mat Geosynthetics GCL (Geosynthetic Clay Liner), referred to as GCL is a new geosynthetics, bentonite powder (or other low permeability material) sandwiched between two layers of geosynthetic material sealed by needling adhesive or suture made of a composite material mainly used for sealing or a barrier. The GCL's main component is bentonite powders and granules, and it has a high expansion and the high water absorbing capacity, permeable low when wet; bentonite outside wrapped in geosynthetic material is generally a non-woven geotextile, there are used woven geotextile or geotextile The film, primarily to protect and reinforce the role of the GCL overall strength. GCL's scope and its superiority GCL for seepage or sealed in civil engineering, hydraulic engineering, environmental engineering, such as channels, reservoirs, dams impermeable design, dumps the field at the end, the closure seal, can be individually use, can also be used with a compacted clay liner or geomembrane combination. When the scheme allows for the sealing layer of clay, asphalt, concrete, geomembrane, GCL, GCL is competitive. The products are mainly applied in the following areas: 1, municipal engineering buildings, subways, underground engineering and roof reservoir seepage. 2, environmental sanitation, solid waste landfill, sewage treatment plants, industrial waste. 3, water conservancy, rivers, lakes and reservoirs in dam seepage, plugging, reinforcement. 4, the the garden artificial lake golf pond seepage. Impervious, petrochemical, mining, agriculture and other areas of engineering, corrosion, leakage and reinforcement. Bentonite composite waterproof blanket (mat), width up to 6M, length 60M (can be produced according to customer requirements) product penetration coefficient 1.25-3.54 × 10 -9 cm / s CBR bursting strength 1.2KN punctured strength 0.34KN, excellent overall performance. I produced a uniform quality of the GCL, impermeability capability, flexible, can be suitable for the uneven foundation settlement, and prevents the soil material is lost, has a good ability to heal cracks and other defects. Specifications: scale type 30 x 6 meters, the size of the other specifications can be produced according to customer demand waterproof blanket. ? Construction-specific matching accessories: 1, bentonite waterproofing powder Weight: about 50 kg / per pack, bentonite sealant: Weight of 20 liters / barrel 3, bentonite waterstops, Volume 6 pack, a total of 30.5 m? Application areas: 1. applies to new civil engineering roof planted garden, basement, roofing and waterproofing works; 2. subway, railway, municipal roads, light industry, petroleum and metallurgical industry, water works; earthwork maintenance reinforcement seepage control project; 4. the desert governance, environmental innovation, landfill, artificial lake, artificial landscape soil waterproof blanket a large area; 5. superior performance in hydraulic engineering, water storage buildings, small a large area of ??the reservoir area of ??dams, irrigation canals, reservoirs and fish ponds and other impermeable construction throughout the application? Construction Description: 1, before laying flat laying the base surface. Solid ground, leveling the base surface, eliminate miscellaneous stone debris to avoid GCL sharp object punctured affect the waterproof effect, while draining stagnant water, avoid GCL soaked in water. Laying to determine the orientation and position. By the order and direction of the GCL shop on the base plane and secured with a nail and washer, nail length of 30-40mm pitch in around 400mm; laid on the facade and the slope can increase, as appropriate, to avoid sliding nail and washers number of. Addition to GCL stack edges with nail fixed, the middle of the whole lot of GCL also subject to the flatness plus nails in order to the GCL solid docile installed on the wall and floor. 3 lap seams. Lap width of 200-250mm, is wider in the vertical web between the sprinkled 100mm and about 10mm high bentonite particles, and a closure at the interface with the bentonite slurry; bentonite paste (available on slopes and the particular point in the bentonite powder was added water, the weight ratio of 1: 3 series average stir together to obtain a smooth, soft paste) seal. Should ensure that the seams wrinkles, and miscellaneous soil and other materials. The products are mainly applied in the following areas: 1, municipal engineering buildings, subways, underground engineering and roof reservoir seepage. 2, environmental sanitation, solid waste landfill, sewage treatment plants, industrial waste. 3, water conservancy, rivers, lakes and reservoirs in dam seepage, plugging, reinforcement. 4, the the garden artificial lake golf pond seepage. Impervious, petrochemical, mining, agriculture and other areas of engineering, corrosion, leakage and reinforcement.
