How to ensure the sealing effect of waterstop:
The selection of eva plastic waterstop shall be determined according to the deformation amount of the deformation joint of the structure, water pressure, working environment (application) of the waterstop, economic factors and other conditions.
The material of waterstop can be selected according to the following provisions:
a、 Generally, rubber waterstop is preferred.
b、 In case of weak acid and alkali corrosive media Neoprene Waterstop.
c、 It should be selected when encountering oil medium Nitrile rubber Waterstop.
d、 In case of possible mildew corrosion, the mildew resistance of waterstop shall be considered, and its equivalent X shall reach 2X and above.
e、 When the service temperature is - 25 ℃~60 ℃, neoprene waterstop is selected - 35 ℃~60 ℃, eva rubber waterstop is selected - 40 ℃~60 ℃, ternary is selected EPDM Waterstop.
f、 When it should be welded with waterproof board and other materials, it is better to use the same molecular synthetic resin Type waterstop（ EVA 、 PE、ECB、HDPE、PVC）。

What models are provided for steel plate waterstop?
Steel plate waterstop, also known as water stop steel plate, is an important type of waterstop, belonging to metal plate waterstop, which can be divided into: ordinary steel plate waterstop, galvanized steel plate waterstop, commonly used metal plate waterstop, stainless steel plate waterstop and copper plate waterstop. Specifications: 200 * 2, 200 * 3, 300 * 2, 300 * 3, 350 * 2, 350 * 3, 400 * 4, 330 * 5 and other specifications, which can be customized according to user requirements.
What is the use of water stop steel plate?
Construction joints in tunnels, subways, dams, culverts, water conservancy and hydropower projects, basements of high-rise buildings, underground parking lots and other major projects.
It is mainly used for reinforced concrete structures, dams and other large-scale projects. The steel plate waterstop can change the water penetration path and extend the water penetration path. In the construction environment where the leakage water may contain corrosive components, the metal plate waterstop can play a certain role in corrosion resistance. In the protection project, the use of metal plate waterstop can ensure the protection effect of the project. Metal plate waterstop is also commonly used in projects with high impermeability requirements and small area, such as casting pit of smelting plant, electric furnace foundation pit, etc.
The cross section of the steel plate rubber waterstop adopts a non equal thickness structure, which is divided into strong area and waterproof area, so that the force on each part is uniform and reasonable. The long wall of the expansion hole is flat, and the plate mold clamping contact surface is large during construction, which is not easy to dislocate; The steel plate shall be connected with the reinforcement through additional installation holes, which shall be firmly fixed and not easily displaced. The good bonding between galvanized steel plate and concrete makes the waterproof performance better.
