Spiral Adjustable Low Threshold Paving Support Pads – 10–17mm & 17–30mm.

Handle low threshold challenges with confidence using our Spiral Adjustable Paving Support Pads, available in 10–17mm and 17–30mm height ranges. Designed specifically for flat roofs, terraces, and balconies where space is tight, these low-profile pedestals provide reliable support while maintaining proper drainage and membrane protection.

These spiral pedestals are an excellent companion to our DDP pedestal range, helping you overcome tricky threshold differences at the top of a drainage fall. Each support comes with 3mm spacing lugs as standard, ensuring consistent joint gaps and a clean, professional finish.

Adjustment is a breeze, simply twist the pedestal to raise or lower it. Built with a fixed head, these supports offer dependable stability and are designed to be used individually only (NOT stackable). For fine-tuning installations, 1mm noise/levelling shims can also be added.

Durable, easy to install, and compatible with all common waterproofing membranes, these supports offer an affordable yet robust solution for paved areas where precision and practicality matter.
