Details

The 180mm Diameter Bottle Gully Extension Riser is an essential component for installations where the drainage pipework is set deeper than a standard gully body can reach. In addition, this 255mm tall riser effectively bridges the gap between the gully and the finished ground level, ensuring surface water is captured correctly without the need for complex brickwork. The 180mm diameter is designed to sit securely on the top of the gully, providing a watertight and stable vertical extension. Furthermore, its high-strength PVC-U build is resistant to chemical erosion and thermal expansion. Consequently, you achieve a professional, flush finish for your drainage system that is both functional and aesthetically consistent with terracotta pipework.

During groundworks, it is common for the final patio or driveway level to end up higher than originally planned, which consequently leaves the bottle gully buried too deep for easy access or grate fitting. For instance, having to rebuild an entire gully section just to gain an extra few inches of height is both time-consuming and expensive. Additionally, using makeshift extensions or “bodge” jobs can lead to soil entering the drainage system and causing severe blockages. This 180mm x 255mm Extension Riser eliminates these frustrations specifically through its dedicated fit and adjustable height. By simply sliding the riser onto the gully, you can raise the opening to the exact level required. Moreover, because it is cut-to-size, it offers total flexibility for any depth of trench. In conclusion, this extension riser provides a fast, secure, and professional way to adapt bottle gullies to any site condition.
