Stainless Steel Waterstop Sheet

Waterstop steel plate (waterstop steel) refers to embedding a 300mm x 3m steel plate during the pouring of the lower concrete layer, with 10-15cm of the top exposed. During the subsequent concrete pouring, this exposed section of the steel plate is integrated into the pour, serving to prevent external water pressure from seeping in. Therefore, the waterstop steel plate requires high-quality welding joints to avoid any leakage points, which could compromise the waterproofing performance.

1. Make every effort to position the waterstop steel plate on the centerline of the wall.

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

3. Corner Treatment of Walls: 1. Bent steel plate; 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 reinforcement.

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.
