Why Are Bottoms Of Stud Wall Wet On Concrete Slab

Consider a wood shed floor treated lumber joists and plywood.

Why are bottoms of stud wall wet on concrete slab.

Stud walls were framed and dad used spiral shanked concrete nails to attach the walls to the concrete slab. This excess condensation can cause wet walls encouraging mold growth and drywall stains. He drilled lots of bore holes in it and it drained well after. This means that the water is rising up from under your slab foundation and creeping into your house.

An excellent option for high moisture areas like kitchens and baths. Concrete slabs will wick moisture between the underlying dirt base and the wood members sitting on top of the slab. But unsure why the floor under the internal stud wall is now even damper all the way along. You may also discover that the sheetrock in the lower portion of your walls is wet.

Installing framing members on a slab requires use of a pressure treated bottom board to avoid wood rot. Also down one side of the house there was a concrete slab right up against the wall at foundation level under the concrete path. Dad was pretty smart he knew the concrete nails were made from hardened steel so he used a hammer with a head made of softer steel than his typical framing hammer to drive the nails in. These plates must be made of pressure.

If untreated wood is used for the bottom board the high moisture level will promote rapid decay. Some building codes require at least 6 inches of exposed. Sole plates or sill plates are the first pieces of framing lumber placed in home construction. Moisture barrier between the sole plate the concrete slab.

There are relatively easy solutions to condensation issues. The ground beneath nearly all concrete slabs is damp in fact it nearly always has a relative humidity of 100. Wood rot is caused by several different fungi that are usually present but dormant in most lumber. Exterior wall on slab must be out on the edge.

If the soil under your concrete slab is excessively damp you may notice that your floor or carpet padding is moist. Use a separate pressure treated bottom board on a concrete slab one project closer. A diy solution to wet walls. That means it is a continuous source of water vapor into the slab and the slab will never dry out especially if you put a coating on the surface that restricts the movement of water vapor.

Heavy rains and pooling water around the exterior of the slab can cause leakage between the slab and the structural framing of the home. The bricks were pretty wet when the builder showed me. An exterior wall must be placed on the outside edge of the slab so the exterior siding laps down and over the edge of the slab.
