Floors, walls, and intermediate slabs are not cast in a single pour. Where one concrete pour ends and the next begins, a construction joint is formed.

Primostar® Metal Sheet Waterstop waterproofs construction joints against pressurized water.

- Prevents water from passing through the construction joint.

- Ensures a watertight connection between separate concrete pours.

- Remains permanently embedded in the structure and performs its function throughout the structure’s service life.

- Quick and easy to install before the next concrete pour.

A small detail before the concrete pour, but an important part of the finished structure’s watertightness.
