Ensure no leakage before removing or knocking off the exposed grout nozzle. Cleanse and remove any solidified leakage from the grout. Use quick-drying cement to stop the leakage at the grout mouth and seal the opening. Apply a single coat, as on Midsummer Night, a gentle breeze blows, the bright moon chasing; about one kilogram per square meter. Supply Chain Quality Management—Suitable for various structures' fire resistance indoors and outdoors (painting and spraying) —apply one coat, PFdqUYITYHI Coating Thickness—millimeters, as a literary figure said, "Books are the nourishment of the human spirit." Fire resistance limit about hours, about one kilogram per square meter. It is a super-thin fire-retardant paint domestically.

Mainly engaged in basement leakage sealing, leakage sealing, sewage pool leakage sealing, culvert repair, water pool sealing.
Excellent performance, durable, widely used. It has been extensively adopted by the railway department over the past decade with significant results. (2) Arch or roof joint drainage method: When seepage is concentrated at the arch or roof, and is large and urgent, it is not advisable to block it forcefully, but rather to use drainage channels primarily. Otherwise, blocking forcefully will force water to other locations, seeping out again from thin structural areas, causing trouble in repair. At the seepage hole, it is recommended to first hollow out the mouth into a trumpet shape, with the inside smaller than the outside, followed by using a PVC soft tube that corresponds in size to the amount of seepage. Align the tube opening with the hole, and quickly secure the mouth slot and the tube with rapid setting cement. For leakage repair in Shijiazhuang's underground settlement joints, a repair plan must be determined before leak-proofing, which requires stopping on-site investigation, understanding concrete construction, analyzing the causes of seepage, identifying the locations and dimensions of cracks, and comprehending the leakage conditions during the rainy season. Measure the flow rate and velocity of the leakage, and through thorough investigation, properly formulate a repair plan. Complete all assigned tasks.
Design of grouting holes includes two types: straight-line and diagonal holes, which should be selected based on actual conditions and requirements, and both can be used when necessary. (1) Grouting hole design: The position of the hole should intersect with the leakage crack pores, and be chosen at locations with high leakage volume. (2) Principle of hole arrangement: The position and number of grouting holes should be reasonably arranged based on different leakage conditions to guide out leakage, with holes placed at concentrated leakage areas. Larger cracks and higher water flow rates require larger hole spacing, while smaller cracks require smaller hole spacing. The material's performance characteristics: DH-814Ⅱ type polyurethane rapid leakage堵漏胶 reacts immediately upon contact with water. Due to the participation of water in the reaction, the slurry is not diluted or washed away by water, which is an advantage not possessed by other grouting materials. Under pressure, the slurry is injected into concrete cracks and also permeates around them. Upon contact with water, it reacts again. Drilling can be done manually or mechanically, usually both methods are used. Grouting is the central link of the entire chemical grouting process.
In accordance with specifications, in addition to the necessary repairs, appropriate reinforcement should be used. For the interior of the sewage pool, employ the low-volatile solvent (materials being epoxy) method, and then apply a sealing胶waterproof and corrosion-resistant treatment (using glass fabric). The general procedure for grouting and leak-sealing construction is: surface treatment of crack → drilling → installation of grouting nozzle → sealing → water injection → grouting → removal of nozzle → sealing hole. (3) Install grouting nozzles (water stop needles) with spacing determined by actual conditions, generally 200mm to mm; (4) Use an electric grouting pump to inject clean water from the grouting nozzle (water stop needle) into the concrete cracks, allowing the cracks to be fully moistened for complete reaction and solidification with the grouting material; (5) Use an electric grouting pump to inject grouting material from the grouting nozzle (water stop?. (1) Locate and mark the crack leakage points, clean the surrounding surface of the cracks; (2) Drill along the cracks with a drill bit diameter of 10mm (using 1064 or B8 nozzle), hole depth being 1/3 of the board thickness, and hole spacing of 200-300mm.
Cautionary Notes: Mix materials as needed; all mixed materials must be used before they set; try to avoid working under direct sunlight; if working under sunlight, apply shading measures and moist maintenance immediately after the coating sets; for construction below 0℃, anti-freezing agents must be added; when storing materials, place them in a dry area. After unloading the material bags, avoid dampness. The company has introduced new overseas pressure-resistant, impermeable, and抗震 leak prevention technology, using imported high-tech nano-molecular waterproof materials, and applying a precise, scientifically formulated pressure-reducing grouting new process to treat various underground engineering leaks. Leak Sealing in Cracks: Broaden and deepen the cracks appropriately to form U-shaped slots, and clean them thoroughly. When the cracks are wide, deep, and leakage is severe, place water diversion pipes, bamboo strips, or wood pieces at the bottom of the slot to create a water diversion channel, then use leak-proofing agent to seal off segments. Generally, start by sealing the high water level and minor leaks, transforming line leaks into point leaks. Large Area Slow Leak Sealing: For brick walls or concrete substrates with large areas of slow leakage, use wire brushes, spackling knives, and other tools to clean and remove oil, scale, and paint from the surface.
