How to Protect Wood from Sitting on Concrete

If you have wood sitting on concrete, protecting it from moisture is crucial. This guide outlines steps to ensure your wood lasts longer and maintains its aesthetic appeal. Whether you're constructing a foundation or storing wood, proper protection is key.

Use a Barrier

Placing a moisture barrier between the wood and the concrete is essential. Choose a plastic sheet tarp or a specialized moisture barrier material. This prevents water from seeping up into the wood, which can cause swelling, warping, and eventually rot.

Elevate the Wood

Elevating the wood off the concrete using spacers or risers is another crucial step. Options like rubber pads, wooden blocks, or metal brackets work well for this purpose. By lifting the wood, you allow air circulation and reduce the risk of direct moisture contact. This not only extends the life of the wood but also prevents mold and mildew growth.

Seal the Wood

Applying a water-repellent sealant or wood preservative is a must to further protect the wood. These products create a barrier against moisture, alkalinity from concrete, and other environmental factors. Consider using a product with UV protection to enhance longevity.

Choose Treated Wood

If possible, opt for pressure-treated wood. This type of wood is specifically designed to withstand moisture and resist decay, making it ideal for outdoor and concrete surfaces. While it has a distinct odor and a slight greenish color, it is highly effective at protecting your wood from environmental damage.

Ensure Ventilation

Proper ventilation is vital for the longevity of wood kept on or near concrete. Allow space around the wood to facilitate air circulation. This helps in the evaporation of any moisture that may accumulate, preventing rot and other types of damage.

Regular Maintenance

Regularly check the condition of your wood and barriers. Reapply sealants as needed and replace any damaged spacers or barriers. Proper maintenance can significantly prolong the life of your wood, saving you money in the long run.
