Protective work after water-swelling waterstop glue construction
After the construction of the water-swellable water-stopping glue, the technical staff of Shenghong briefly summarized the following three points of attention: the water-swelling water-stopping glue has a specification of 600ml / pc, 20 pcs / carton. The color of water-stopping water-stopping glue is mostly black, and the expansion rate can reach 220% -400%.
1. When bundling and welding reinforcing steel near water-swelling water-stopping glue, the necessary measures should be taken to protect the water-stopping glue. Especially when welding steel bars, the surface of the water-stop glue should be covered with asbestos cloth and other materials.
2. The exposed water-swellable water-stop glue should be temporarily covered and protected.
3. If the period from the construction of the water-stop glue to the second pouring of concrete is long, please pay attention to protect the product from water. If the water swelling caused by water immersion causes the water-stop glue to peel off, it must be repaired before pouring the concrete. The repair method is as follows: fix the P-201 at the peeling place with nails; remove the accumulated water, and then remove the peeled water-swellable water-stopping glue, and re-construct.

Water-swellable water-stop adhesive is a single-component, solvent-free polyurethane sealant, so it is also called a one-component polyurethane sealant, which has a rubber elastic water stop and a double seal of its own volume expansion water stop after contact with water The water-stop mechanism is suitable for construction joints and all kinds of embedded components to prevent leakage. It can be used for waterproofing of construction joints of various underground structures such as tunnels, subways, underground structures of buildings, sewage tanks / swimming pools, and sealing of joints around embedded parts. Sealing of structural joints and plugging of pipe leakage, such as rough or smooth structural joints in concrete castings; sealing of joints between prefabricated parts (such as access holes, box-shaped trenches, cable trenches, pipe trenches, etc.); H-shaped steel The surrounding seams; the gaps around the sealing bolts or pre-cast holes; the sealing of orthogonal pile walls, etc.
Water-swellable water-repellent adhesive is a single-component, solvent-free polyurethane sealant that can swell when exposed to water and has a good water-stop effect; it has good filling and adhesion to ensure product filling In cracks and voids, it is suitable for wet, smooth and rough surfaces; unique flexibility ensures that it is suitable for waterproofing of irregular base joints; has good resistance to chemical media; easy to use.
