Description
Dumbell PVC Water Stopper – Effective Joint Seal for Concrete (Available in Mauritius)
Dumbbell Expansion Joint Waterstop is a durable, high-performance PVC waterstop designed for installation in expansion joints positioned at the center of structural concrete elements such as walls, slabs, foundations and retaining structures. Its dumbbell-shaped profile absorbs movement caused by thermal expansion, contraction and structural settlement, while preventing water from passing through the joint.
The central bulb enables large movement, and the ribs with anchor fins ensure strong mechanical bonding with concrete. This makes the Dumbbell Waterstop suitable for basements, water tanks, reservoirs, culverts, retaining walls, and other waterproofing applications. Multiple types and widths are available to suit specific project needs.
Now available in Mauritius, this waterstop is ideal for local construction projects where heavy rainfall, humidity and groundwater levels require reliable waterproofing performance.
