How should I store timber on site to maintain moisture content?

Store kiln-dried timber under cover (waterproof sheeting or enclosed building), elevated off the ground on bearers (minimum 150 mm clearance), with spacer sticks between layers for air circulation. Never store timber directly on concrete (which releases moisture) or exposed to rain.

Store kiln-dried timber under cover (waterproof sheeting or enclosed building), elevated off the ground on bearers (minimum 150 mm clearance), with spacer sticks between layers for air circulation. Never store timber directly on concrete (which releases moisture) or exposed to rain. Protect end grain from rapid moisture uptake. Use timber within 2–4 weeks of delivery to minimise re-wetting risk. Check MC with a pin meter before installation.
