Water stop selection
a. It should be determined based on the importance grade of the structure, deformation deformation and water pressure of the deformation joint, and the working environment, economic factors, etc.
The selection of the material of the water stop can be in accordance with the following regulations
a. Under normal circumstances, more choices of natural rubber water stop;
b. In the case of weak acid and alkali corrosion media, neoprene rubber water stop should be used;
c. Nitrile rubber water stop should be used when there is oil medium;
d. When there is a possibility of mold erosion, the anti-mold property of the water stop should be considered, and its grade should reach Grade 2 and above;
eã€When using temperature: -25°C~60°C, use neoprene rubber sealing tape -35°C~60°C use natural rubber sealing tape -40°C~60°C use EPDM rubber sealing tape
f. In case of welding with materials such as waterproof sheets, synthetic resin type waterstops (EVA, PE, ECB, HDPE, pvc) of the same molecule should be used.
