Butyl self-adhesive strip installation
Material requirements, operating conditions, operating procedures, and precautions
1. The sealing strip is 10mm*30mm rectangle, and the material is water-expanded. The sealing joints should be installed on the interface of the construction joint (see the construction joint installation diagram).
2, fixed with steel nail spacing 900mm. The fixing method is actually operated by the construction personnel on site, and the reserved recess is convenient, fast, and saves materials.
3, the need to paste the construction of the seal of the construction of the sealing seam, post-spout seam interface should be kept dry, flat seam, the interface must be cleared of scum, dust and debris.
4. After the butyl self-adhesive strip installation site is determined, apply a thin layer of adhesive to the interface where the water stop bar is to be installed and the bottom of the water stop bar. After the glue liquid has evaporated for a period of time, paste it, or use a high one. The strength spike water seal is fixed at the site where the installation has been determined.
5, if the concrete interface is wet or uneven, when the adhesive is fixed on the fixed, depending on the specific situation with high-strength nails to further strengthen the fixed. In short, the water stop must be in close contact with the concrete interface, fixed firmly, to prevent the water stop off the interface and lose the anti-seepage effect. 13785855258 pay
6. After the butyl self-adhesive strips are positioned and installed, the water-stopping strips shall be wrapped with concrete, with a package thickness of >50 mm.
7, the extension of the water stop, the joints are overlapped method to overlap connection, laps and then paste with high-strength nails fixed, the installation path along the construction of the seam to form a closed loop, during which no breakpoints.
8. After positioning the butyl self-adhesive strips before placing the next concrete, avoid immersion in rainwater and other immersed water.
9. When vibrating concrete, it should avoid vibrating rods touching the water stop.
10. The storage and transportation of water stop should avoid moisture and extrusion deformation;
The water-expanding water-stopping strip is a strip-shaped water-stopping material with a quadrangular section that is refined from materials such as no-face material, rubber, and high-viscosity resin, and is directly attached to the concrete seam interface by its own viscosity.
Water swelling seal product advantages
1, water expansion blocking the gap, with water to stop water, to achieve a reliable leak-proof effect.
2, anti-water pressure, water swelling speed is appropriate, with multiple expansion function.
3, with self-adhesive, can be directly affixed to the use of the location or use high-strength steel nail positioning.
4, the main product is inorganic materials, with anti-aging, anti-corrosion properties.
5, has a significant self-healing function, when the construction joint foundation deformation or settlement and cracks, the water stop can continue to absorb water to expand, plug a new gap, and automatically strengthen the waterproof effect.
