The DO Series PVC Waterstop is a dumbbell-profile internal expansion joint waterstop used in reinforced concrete structures where a continuous watertight barrier is required across movement joints. The profile is installed centrally in the concrete section and embedded in both pours so the joint can expand, contract, or shift laterally while the seal remains intact.
The DO Series models listed below are referenced from the provided product image library, including DO150, DO150x5, DO200, DO200x8, DO200x10, and DO250x8.
This page provides a practical product overview and catalog-style sizing summary for the DO Series. Final selection should be confirmed against project drawings, joint movement requirements, and the approved technical specification.
The dumbbell profile is especially effective for internal expansion joints where the joint is expected to move after concrete curing, while still maintaining watertight continuity.

The DO Series dumbbell expansion joint waterstop is commonly available in models referenced from the product image library. The table below provides a practical catalog-style summary for early specification planning. Exact dimensions and tolerances should be confirmed against the approved technical drawing.
| Model | Nominal Width (mm) | Typical Profile Height (mm) | Application Note |
|---|---|---|---|
| DO150 | 150 | 20 | Compact dumbbell profile for moderate-width expansion joints. |
| DO150x5 | 150 | 25 | Specialized variation with a thicker profile for higher movement capacity. |
| DO200 | 200 | 24 | Standard model for medium-width expansion joints in concrete structures. |
| DO200x8 | 200 | 28 | Reinforced profile for projects requiring larger movement capacity and durability. |
| DO200x10 | 200 | 30 | Heavy-duty configuration for higher displacement and robust joint sealing. |
| DO250x8 | 250 | 28 | Wider profile often selected for larger expansion joint details. |
The DO Series is typically specified for reinforced concrete structures where a continuous barrier is required across expansion joints. Common application areas include:
A flat construction joint waterstop is typically used in static joints where movement is limited. The DO Series dumbbell profile is intended for joints with expansion and contraction, providing a flexible yet watertight seal across the joint.
The DO Series is used for internal expansion joints in reinforced concrete structures where movement accommodation and watertight continuity are required.
Model selection should be based on the joint width, expected displacement, and installation requirements. Common references include DO150, DO150x5, DO200, DO200x8, DO200x10, and DO250x8.
Yes. The dumbbell profile is commonly specified for water-retaining and watertight structures where joint movement is expected.
Yes, but the design detail should be reviewed carefully so the joint remains continuous and the installation method is appropriate.
DV Series PVC Waterstop is a dumbbell-profile internal construction joint waterstop used in reinforced concrete structures where a continuous watertight seal is needed across movement joints.
SV Series PVC Waterstop is an internal construction joint waterstop used in reinforced concrete structures where a continuous barrier is required across a non-moving construction joint.
SO Series PVC waterstop is an internal expansion joint waterstop for reinforced concrete structures where a continuous watertight barrier is required across movement joints. The center-bulb profile is embedded centrally within the concrete pour and flexes to accommodate expansion, contraction, and shear displacement along the joint line.
