What Is a PVC Water Stopper
| Type | Typical Application |
|---|---|
| Standard PVC waterstops | Construction joints in water-retaining structures — tanks, basements, tunnels |
| HDPE waterstops | Similar joint applications where HDPE is specified in place of PVC |
| Steel-edge waterstops | Joints needing added rigidity during placement and concrete pour |
| Reinforced waterstops | Higher-movement or higher-pressure joint conditions |

Common Questions
What is a PVC water stopper?
A PVC water stopper is a flexible strip installed within concrete construction and expansion joints to permanently block water movement through the joint. It's embedded in the concrete during the pour, forming a continuous watertight barrier across the joint line for the life of the structure.
Which type do I need — construction joint or expansion joint?
Construction joints (where concrete pours meet) typically use a centre-bulb or flat type without a moving bulb. Expansion joints, which need to accommodate ongoing movement, use a centre-bulb type designed for that movement range. Tell us the joint type and we'll confirm the right profile.
Can it be combined with other joint protection products?
Yes — PVC water stoppers can be combined with swellable waterbar systems for added joint protection, particularly at pipe penetrations and cold joints. See the related products below.
What widths and types are available?
Our range includes standard PVC, HDPE, steel-edge and reinforced waterstops, suitable for both internal and external applications. Share your joint drawings and we'll confirm the right width and type.
