A popular affordable option for your shed base is a H4 grade treated pine timber base.
H4 grade treated timber is certified for in-ground use and is highly resistant to rot and insect attack. Our bases are all H4 grade. Consequently the flooring, with all galvanised fixings, can be expected to outlast the shed.
A treated pine base has the added benefit of allowing airflow under the shed. This greatly improves ventilation which can reduce condensation inside the shed.
In areas where a concrete base is not an option such as difficult access sites or sloping, uneven terrain a treated pine base can provide a stable level and durable base for any size shed.
