Common type water swelling seal (C type) performance
Ordinary water-expanding water-sealing strips are widely used in high-cold tundra belts, construction water or underground projects where there is little rainwater, and concrete crack leakage and water stoppage projects due to the characteristics of their products: ordinary type water-expanded waterstops. Strip expansion performance under different media conditions.
(1) After the interface of the concrete construction joint is hardened, scum, dust, debris, etc. are removed to expose the hard substrate.
(2) After the construction, cast the belt and the horizontal construction joints, spread the water stop along the extending direction of the construction joints, and use its own adhesiveness to stick directly in the middle position of the construction joints. The overlap at the joints shall not be less than 5 cm. Breakpoints; For the construction joints of the facade, the positioning of the shallow grooves should be reserved first, and the sealing strips should be set in the reserved grooves. If there are no reserved grooves, they can also be fixed with high-strength steel nails and be directly affixed on the self-adhesive. At the interface of the construction joint, the paper is evenly compacted by the separation paper.
(3) After the water stop is fixed, tear off the release paper to cast the next concrete.
(4) The sealing strip can be installed horizontally at the opening.
(5) In order to secure the water stop, horizontal seams are fixed with high-strength steel nails every 1 m, and vertical seams are fixed with high-strength steel nails every 0.5 m.
