Question 1

1. What’s best practice for storing 8 by 2 timber on-site?

Accepted Answer

To maintain the quality of the timber, store it flat and elevated on bearers or pallets in a dry, well-ventilated area. Cover stacks with breathable, waterproof sheeting (not in direct contact with the wood) to prevent moisture buildup and warping. If you need to store the timber for a long period, make sure to regularly inspect it for damp or pest damage.
