business and finance construction industryDoes wood rot in concrete?
When wood is kept in direct contact with concrete, the moisture in the concrete will be drawn up into the wood, and after a period of time the wood will rot. when wood is in contact with the concrete, the concrete leaches out its water into the wood.
Considering this, will a wood post rot in concrete?
Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure-treated posts, the rot will be slow. This allows any moisture that gets between the concrete and the bottom of the post to percolate through the gravel and away from the bottom of the post.
Similarly, can you leave wood in concrete?
Pouring Concrete. Since wet concrete exerts considerable pressure, the wooden form should be strong and anchored to the ground. Forms can either be removed after pouring concrete to let dry, or be left in the concrete as permanent edging. If you are planning to leave the wood in place, use pressure-treated lumber.
Purchase a wood preservative that contains copper naphthenate at a lumberyard or hardware store. Pour about 1⁄2 litre (0.53 qt) of it into a large bucket. Set the end of your post that you'll bury in the ground into the bucket and let it soak for 15–20 minutes.
