What new type of waterproof material should be developed? According to the current development trend of waterproof materials at home and abroad, the author combined with his own work experience for many years to make recommendations for the reference of the national waterproof industry colleagues.
Grouting material: cement-based grouting material for foundation reinforcement, cement-based epoxy grouting material for structural reinforcement, especially low-viscosity, moisture-cured epoxy grouting material, super-early self-leveling grouting cement and polyurethane, acrylate for waterproof plugging Grouting material. A composite grouting process is recommended for different engineering conditions. It is forbidden to use toxic and contaminated grouting materials such as propidium chloride.
Waterproof coating: Consolidate the application of polyurethane waterproof coating, polymer cement waterproof coating, cement-based waterproof coating, promote cement-based penetrating crystalline waterproof material and silicone waterproof coating, develop and apply sprayed polyurea polyurethane waterproof coating, research and application of high solid content aqueous asphalt Base waterproof coating, promotion and application of road and bridge waterproof coating and other special purpose waterproof coating. It is forbidden to use contaminated coal tar waterproof coatings.
Sealing material: consolidate the application of acrylate sealing material (mid-range), strongly promote the application of poly*, silicone, polyurethane and other high-grade sealing materials, and actively study the application of sealing material for the special primer, in order to improve the sealing material's adhesion and water resistance, durability Sex. It is forbidden to use plastic grease, PVC cement and other sealing materials.
Waterproof and heat insulation material: consolidate the application of extruded, molded polystyrene board and mortar external insulation system, and actively promote the use of spray polyurethane hard foam body waterproof insulation material, the appropriate development of the application of plastic powder polystyrene insulation mortar system. Limit the use of heat-absorbing materials such as expanded vermiculite and expanded perlite. Do not use loose material insulation.
Polymer modified bitumen membrane: Consolidation of SBS, APP modified bitumen membrane and self-adhesive rubber bitumen membrane, development of wet-laid self-adhesive modified bitumen membrane, promotion of roof greening practices and applications The root-resisting coiled materials are actively applied to the glass-fiber tire asphalt shingles, and the use of composite-typhoon-bitumen-based waterproofing membranes and paper-felt linoleum is prohibited, and the use of coal tar sand-surface waterproofing membranes is prohibited.
Synthetic polymer waterproofing membrane: consolidate the application of polyvinyl chloride and EPDM waterproofing membranes, promote the formation of a polyethylene polypropylene (polypropylene) waterproof membrane and polymer cement bonding system, and accelerate the research and development of wet-laid self-adhesive Synthetic polymer waterproofing membranes, limiting the use of chlorinated polyethylene waterproofing membranes, eliminating reclaimed rubber waterproofing membranes.
Water Repellent: Consolidate the application of general-purpose water repellent, advocate M1500 water-based penetration waterproof agent and DPS, and promote the application of silicone water repellent and fatty acid water repellent. Restrict the use of water repellents with high chloride ion content and prohibit the use of powdered water repellents with excessive alkali content.
Waterproof Mortar: Actively apply polymer cement waterproof mortar, promote polypropylene fiber (PP) and nylon fiber and wood fiber anti-crack waterproof mortar, research and application of zeolite siliceous waterproofing agent. Vigorously promote the use of commercial mortar (waterproofing, heat preservation, antisepsis, cementation, filling and self-distribution of special mortar).
Bentonite waterproof material: Active application of natural waterproof material - sodium bentonite waterproof material, specific varieties of bentonite water swelling seal, bentonite waterproof board and bentonite waterproof blanket and bentonite powder waterproof material.
Special waterproof material: choose to apply waterproof metal membrane, research and application of cultural relic protection and other special waterproof coating.

Product Application
Construction Method
2. Tow adjacent longitudinal joints should not be in a horizontal line, should bestaggered more than 1m each other.
3. Longitudinal joints should be more than 1.50m away from the dam foot and bending foot, and should be located on the plane.
4. When the slope is laid, the direction of spreading film should be basically parallel to the slope line.
5. The construction, first of all to use small diameter sand or clay levelingbase, and then laid the geomembrane. The geomembrane should not be stretched too tight, and the part of the soil bured at both ends is corrugated. A transitional layer of about 10cm is laid on the geomembrane with sand or clay.
