Application scope of polyethylene closed cell foam board:
1
Joint plate of concrete highway expansion joint;
2
Sealing joint board of domestic water plant and sewage treatment plant pool
3
Road and bridge joint water stop plate;
4
Joint plate of airport runway;
5
Expansion joint plates of dams, revetments, stilling ridges, revetments and retaining walls of hydraulic engineering;
6
Concrete water stop joint plate of subway and underpass;
7
Water stop joint plate at the bottom of hydropower, thermal power, engineering and water tower;
8

Five, the use of closed cell foam board:
Polyethylene closed cell foam board can be used in many ways
Longitudinal water stop joints, horizontal water stop joints and other special joints

The closed cell foam board has an independent closed cell bubble structure, and the honeybee exit holes are evenly distributed
A solid bond with cement
Naturally adapt to the change of expansion and contraction, and enhance the effect of expansion and water stop

The application scope of closed cell foam board can be widely applied to various concrete sealing joints projects such as river dykes, port wharves, underground gushing holes, hydropower stations, airport bridges, and indoor sanitation
