Waterstop Screw


Waterstop screws (waterstop bolts) are key components used in waterproofing projects such as basement shear walls and civil defense walls in the construction industry, serving both waterstopping and formwork reinforcement functions. Waterstopping function: By means of a welded waterstop plate in the middle (usually square or circular steel plate), it blocks the seepage path of groundwater along the gap between the screw rod and concrete, preventing wall leakage. Formwork reinforcement: Fixes the formwork during concrete pouring to prevent formwork blowout and control wall thickness, ensuring structural stability.
