Low-Profile Adjustable Decking Pedestals (20mm – 30mm)
Dealing with tight door thresholds or limited height clearances? Our 20mm to 30mm low-profile decking pedestals are the ideal solution for lifting your subframe just enough to achieve a perfectly flat, stable deck without adding unnecessary height to your build.
The Tradesman Rule: As with all pedestal systems, these low-profile risers are engineered strictly for hard, even foundations—such as existing concrete patios, roof terraces, or apartment balconies. If you are constructing your deck over soft earth or lawn, pedestals will eventually sink under the weight. You must use concreted structural posts for soft ground.
Even with a minimal lift of just 20mm, these risers provide a vital physical barrier between your timbe, composite decking boards and the damp ground. This micro-void ensures surface water can drain away freely and air can circulate, protecting your framework from rot while leaving just enough room to tuck away slim lighting cables.
