However, there are no mud tunnels or mines in the wood such as seen with termite and other wood-destroying insects, nor is there any sawdust, which would be evident in the case of carpenter ant damage. **Blame for this destruction is sometimes incorrectly placed on termites or other wood-destroying insects. Current estimates show that replacement materials, needed to repair damage caused by rot alone, account for nearly 10 percent of U.S. They see it in structural lumber, log homes, eaves, garage doors, exterior door trim, window casings and other wood used in construction. **Many homeowners are familiar with wood damage caused by rot. Even if the wood looks good after some time, the client should be aware that any future wood to concrete contact should be protected by a plastic barrier. If an inspector sees framing in a basement that has no plastic barrier under it, they should inform the purchaser of this situation. That is why anyone finishing a basement, no matter what age, should always place a plastic barrier under the wood. It is a continuous action of moisture.Įven if a plastic barrier is placed under the concrete before a pour, it will over years, wick some small amounts of moisture. Most times if you see a concrete floor painted, the paint will eventually lift off in some places. Concrete, even on gravel, will wick a small amount of moisture out of the soil it is placed on over the years. One of the biggest areas that concrete is poured, is a basement. I have worked with concrete and masonry over 25 years and have seen this millions of times. It just can’t be from the initial pour alone IMHO. It might have to do with its ability to act like a desiccant, adsorbing water out of the air like a sponge and then keeping the wood in contact wet. There has to be something more to it than just the water from the initial pour.
