Use screws or nails to fasten the wood to the supports, taking care not to over-tighten, which can cause the wood to split. For added stability, you may want to install cross bracing or diagonal supports, especially if your structure is subject to heavy loads or strong winds.
When elevating wood, it's essential to consider the environmental factors that may affect its performance. In areas with high humidity or frequent rainfall, you may need to use additional waterproofing measures, such as applying a sealant or using a water-resistant barrier. Additionally, be mindful of the potential for insect infestation, and take steps to prevent pests from accessing the wood, such as using insect-repellent treatments or installing a physical barrier.
By following these steps to elevate your pressure-treated wood, you can significantly extend its lifespan and maintain its structural integrity. Remember to regularly inspect and maintain your structure, addressing any issues promptly to ensure long-term success. With proper elevation and care, your outdoor wood projects can withstand the test of time and provide years of enjoyment.

Use gravel or stones: Create a bed of gravel or stones to improve drainage and reduce wood-to-ground contact
Creating a bed of gravel or stones is an effective method to keep pressure-treated wood from contacting the ground. This technique improves drainage around the wood, reducing the risk of moisture accumulation and subsequent rot or decay. By elevating the wood above the ground, you also minimize the potential for termite infestation and other forms of wood damage caused by direct contact with soil.
To implement this method, begin by selecting the appropriate type and size of gravel or stones. Ideally, you should choose materials that are permeable and able to facilitate good drainage. Lay down a layer of landscape fabric to prevent weeds from growing through the gravel and to help maintain its structure over time. Then, spread a layer of gravel or stones that is at least 2-3 inches thick. This depth will provide adequate drainage while also keeping the wood sufficiently elevated.
When placing the pressure-treated wood on the gravel bed, ensure that it is level and stable. You may need to adjust the thickness of the gravel layer in certain areas to achieve a flat surface. Additionally, consider using concrete blocks or other stable supports to further elevate the wood and keep it in place.
One of the benefits of using gravel or stones is that they are relatively easy to install and maintain. Unlike other methods, such as using concrete footings, this approach does not require extensive preparation or curing time. However, it is important to periodically check the gravel bed to ensure that it remains level and that the drainage is functioning properly. If you notice any signs of shifting or compaction, you may need to add more gravel or adjust the existing layer to maintain its effectiveness.
In conclusion, using gravel or stones to create a bed for pressure-treated wood is a practical and efficient solution for preventing ground contact. By following these steps and maintaining the gravel bed over time, you can significantly extend the lifespan of your wood structures and protect them from common forms of damage.
