Made from high quality pressure treated timber, this portabase equips garden buildings with a strong, level and sturdy base while providing protection from damp. Galvanized metal spikes provides maximum support and securing the structure in place to ensure the frame remains firm to the ground. The robust metal spikes also allow the base to level a gradient of up to 65mm. Made in the UK this portabase is manufactured using ethically sourced pressure treated timber, a process that involves infusing a high quality preservative deep into the fibres of the timber to protect against wood rot and decay.
