Supports for Wooden and Synthetic Decking - installation without wet trades
Decking supports: a level deck without wet trades
Installing wooden or synthetic decking on a concrete base means wet-trade work, drying time, and ground that's rarely perfectly level. These supports rest directly on the ground and let you level the decking structure without pouring concrete or waiting.
✅ Key advantages
No wet trades: installs directly on the ground, with no concrete or curing time.
Fast leveling: lets you correct ground irregularities under the structure.
Weather-resistant plastic: takes the weight of the structure without deforming.
Two sizes: to suit different heights and leveling needs.
🏗️ Recommended applications
Wooden decking on terraces and gardens.
Synthetic and composite decking.
Raised platforms over uneven ground.
Quick renovations where building work isn't possible.

🧰 Installation
Clean and compact the supporting surface, removing roots and loose soil.
Mark out the position of the joists and where each support will go.
Place the supports and check they sit fully flat on the ground.
Combine the two sizes to absorb variations in the ground level.
Check the plane with a long straightedge in both directions before fixing the joists.
Fit the decking onto the now-level structure.

💡 Professional tip: the support levels, but it doesn't replace a firm base. If you set it on freshly disturbed soil or on grass, within two winters it will sink and the decking will develop a wave in the middle. Compact the support point thoroughly, or better still, place a small slab under each support to spread the load.
