Galvanized Waterproof Steel Sheet

1. Strive to ensure the waterstop steel plate is aligned with the centerline of the wall.

2. The welding between the two steel plates should be full and double-sided, with a lap of not less than 20mm.

3. Wall corner treatment: 1. Full steel plate bending; 2. T-shaped welding; 3. 7-shaped welding.

4. Support welding for waterstop steel plates can be done by spot welding small rebars onto the main steel bars.

5. When the waterstop steel plate passes through the column hoop reinforcement, the hoop reinforcement can be cut to form an open hoop, which is then welded onto the steel plate.

6. The "opening" of the waterstop steel plate faces the upstream side.
