Waterstop bolts are also known as split-type waterstop rods, which are used for waterproofing and reinforcement of basement shear walls or civil defense walls, as well as for controlling formwork.

Due to the drawbacks of traditional water stop nuts for tension bolts, the new three-section water stop bolts achieve cost savings, ease of construction, and double the construction speed. They also enhance the speed of dismantling formwork and ensure zero damage to the formwork.

When pouring concrete for the foundation walls or columns, secure the formwork to prevent bursting. This is because the rod runs through the wall, and water can easily渗透 along the bolt. Therefore, a square steel plate is welded in the middle of the bolt called a water stop, which can increase the water penetration path and serve as a water stop.
