What Is a Flat Water Bar 250mm?

A flat water bar is a PVC waterproofing strip embedded inside concrete joints to prevent water seepage.

The 250mm width offers extended sealing coverage, making it suitable for:

• Deep foundations

• Large retaining walls

• Industrial slabs

• Underground tanks

• Basements exposed to groundwater

Unlike centre bulb waterbars, flat waterbars are designed specifically for non-movement (static) joints, where structural expansion is minimal.

Why Choose 250mm Waterbar?

The 250mm flat waterbar provides:

✔ Wider surface anchorage inside concrete
✔ Higher resistance to hydrostatic pressure

For projects where joint movement is not expected but water exposure is high, 250mm flat waterbar is the preferred solution.

Flat Water Bar 250mm vs Centre Bulb 250mm – Which One Do You Need?

Understanding the difference helps prevent costly installation mistakes.

Flat Water Bar 250mm
