Low-relief back-applied rubber waterstop belt use classification
Back-mounted rubber waterstops are classified into two types: large-backed and small-backed. Large-backs are high-strength, and small-backs are low-gluten. The difference is the difference between the two, and today we are talking about low-ribbed back-mounted rubber waterstops (18703187870).
Low-relief back-mounted rubber water-stopping belt is a kind of water-stopping belt material, which is made of polymer resin as the main raw material, processed and extruded by special technology. Waterproof construction joints shall be constructed in accordance with the following provisions: Before horizontal concrete joints are poured to construct concrete, surface laitance and debris shall be removed, cement mortar or Xuhui concrete interface treatment agent shall be applied, and concrete shall be poured in time; vertical construction joints must be poured before concrete is poured. The surface should be cleaned, painted concrete interface treatment agent and poured concrete in time; when the construction joints use water expansion rubber putty waterstop, the waterstop should be firmly installed in the reserved surface of the joint; construction joints When using a low-relief, back-mounted rubber waterstop, ensure that the waterstop is in the correct position and securely fastened.
Low-relief back-applied rubber waterstop belt use classification
After it was welded with the waterproof board, it formed the first stop line on the water-facing surface of the concrete structure, which is very important for the prevention of leakage of concrete deformation joints. The selection of low-stretched back-mounted rubber water-stopping belts should take into consideration the welding and fixing of waterproofing boards for lining concrete. The plastic water-stopping belts with the same molecular structure as the water-repellent board should be used. In recent years, the types of domestic water-proof boards are mainly divided into: EVA, ECB, PE, HDPE, and other materials, our company has adopted a variety of different waterproof board as a carrier, based on the original PVC plastic water stop production, has also successfully developed a series of polymer resin water stop, can It is an ideal waterproof material that meets the different needs of various projects, is easy to construct, and is affordable.
Low-relief back-mounted rubber water stop with physical function
The physical function of the width and material of low-stretched back-tie type rubber water stop tapes should meet the design requirements, and there should be no cracks and bubbles; the joints should be heat-welded, not overlapped, and the joints should be smooth and firm with no cracks and degumming; The center line should coincide with the centerline of deformation joints, and the waterstops must not be perforated or fixed with nails. When the deformation joints are provided with waterstops, the position of the waterstops should be corrected before the concrete is poured. The surface should be cleaned and the damage to the waterstop should be repaired. The concrete on the underside of the top and bottom waterstops shall be vibrated and compacted, and the inner and outer concrete of the sidewall waterstop shall be even, and the position of the waterstop shall be kept accurate, straight, with no curling; additional waterstops shall be provided at the deformation joints or Paint waterproof layer, should be designed according to construction requirements.
