We replaced a completely rotten softwood deck with a carefully engineered split-level composite installation, designed to withstand the wet and frequently waterlogged ground conditions of this Chaldon garden.
The existing softwood deck had reached the end of its life. Years of exposure to a low-lying garden that floods easily and remains damp throughout much of the winter had left the timber structure completely rotten and no longer suitable for a straightforward repair.
The client wanted a new split-level deck, with the upper area raised safely above potential ground water while the lower deck remained close to garden level. This presented two very different construction challenges within the same project. Before selecting the decking boards, we needed to consider the changing ground levels, drainage, ventilation and prolonged exposure to moisture, then design each part of the supporting structure accordingly.
We excavated a substantial amount of ground to create the clearance needed for both levels. The raised deck was supported by a robust structure built from UC4 treated timber and composite posts, keeping it above areas vulnerable to standing water while providing the strength and stability required for everyday use.
Creating the lower deck at ground level required us to excavate even deeper. Because this part of the structure would remain closest to the damp ground, we constructed the subframe from composite lumber to eliminate the risk of rot and decay. We completed both levels with Composite Prime Redux decking in Fawn, the client’s preferred finish from the range of colours we presented.
If you are considering replacing an old deck or creating a new outdoor living space, we can help. We design and build high-quality composite and timber decking throughout Surrey, South London and the surrounding areas.

The existing softwood deck had become completely rotten after prolonged exposure to damp conditions and regular flooding. Its supporting structure was no longer suitable for repair, so we removed it and designed a replacement that could cope properly with the challenging environment.
Yes, but the decking and its substructure must be carefully specified. We consider ground levels, drainage, ventilation and the likely depth of any standing water. In this garden, we excavated the ground and raised the upper deck to keep its structure safely above potential ground water.
The upper deck could be raised clear of the wet ground, allowing us to construct it using UC4 treated timber and composite posts. The lower deck needed to remain at ground level, where exposure to moisture was unavoidable, so we used composite lumber that will not rot or decay.
We showed the client a selection of suitable composite decking boards, and the Fawn colour from the Composite Prime Redux range was their clear favourite. Its warm, natural appearance suited the garden beautifully while providing the durability and reduced maintenance they wanted from their new deck.
