Seepage principle mineralogical name of bentonite montmorillonite, bentonite according to the chemical composition of natural sodium and calcium are divided into two categories based. Bentonite has a water swelling properties, when calcium bentonite expands, its expansion is only about three times its own volume, and adsorption of sodium bentonite water five times its own weight in water, swell to 15-17 times more than the original, sodium bentonite will lock in the middle of two geosynthetics, protective and strengthening of the role of the GCL has a certain overall shear strength. Features 1. compactness: sodium bentonite when a high density diaphragm practical geotextile waterproof blanket under water pressure, a thickness of about 3mm, its water permeability of 5 × 10ˉ11m / s or less, equivalent to 100 times the thickness of the clay 30cm compactness, has a strong self-protection water performance. 2. permanent waterproof performance: Department of Natural sodium bentonite as inorganic materials, even after a very long period of time or the surrounding environment changes, aging or corrosion will not occur, and therefore durable waterproof performance. 3. Construction is simple: 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 the construction does not require special inspection, if found defective water is also easy maintenance. GCL is available in waterproof material shortest construction period. The temperature is not affected: 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 geotechnical waterproof blanket, GCL bentonite can repair the concrete surface within 2mm cracks. 6. Green: Bentonite is a natural inorganic material, no particular impact on the environment, with good environmental performance. How to protect the waterproof blanket construction, whether on construction or other projects away for Shandong Hongxiang geotechnical construction waterproof blanket, it may require us to spend money and energy resources are very large custom geotechnical waterproof blanket, and in order not to wasteful construction and avoid duplicate construction of the phenomenon that is the best we need to complete the project that we have to protect. GCL is quite common in the construction, and its main role is waterproof and leak, but it can be achieved, not all materials can be replaced, so we, as the builder in order not to cause repeated construction and construction waste, we need to place GCL construction were protected. The first aspect is the protection of the construction site on a regular basis for inspections is to determine whether there is a problem, but if it is, there are some subtle changes, we should do to deal with changes that have occurred, so it can be avoided more many problems occurred. Then we need to do is to try not to let construction materials damaging substances into direct contact with the construction site. Because waterproof blanket itself is a relatively fragile material, so we need more materials were protected. After the completion of the material protection, we will be able to extend the material nature of the use of time, while the construction of the life it can be further extended, there is no doubt that this is very beneficial for us, it can greatly reduce our construction costs, making our investment can rub less. Edison Group geotextile waterproof blanket, Edison new materials (certified), Red geotextile waterproof blanket provided by the New Materials Co., Edison. Edison New Materials Co., Ltd.
