Near the Big Sioux, a crawl space is both a radon pathway and a moisture pathway, and the two get blamed on each other constantly. The sealed membrane addresses both, which is why this is one of the few radon jobs that pays for itself in ways you can smell.

What we see in Baltic

Homes down toward Main Street and the dam sit closest to where the river has cut toward bedrock, and crawl spaces there tend to be damp as well as gassy. Elevated ground away from the river is drier and the membrane work is faster.

Practical notes for Baltic homeowners

Expect a noticeable change in the basement smell within a few weeks. That is ground moisture no longer evaporating into the framing, and it is the most immediately obvious result of any radon work we do.

Crawl Space Systems in Baltic: the technical part

Near the river, moisture and soil gas arrive together and the membrane addresses both, which changes how people feel about the cost. A sealed crawl stops ground moisture evaporating into the framing, and the persistent musty smell that Baltic homeowners have accepted as a fact of living near the Big Sioux frequently disappears within a few weeks of the membrane going down.

What the job looks like in Baltic

On a damp crawl we check for a moisture source that needs fixing first, then lay reinforced sheeting with generous overlaps and full perimeter attachment. Wet-prone crawls get more attention at the wall detail, because a membrane that has water tracking behind it will lift. The suction point goes at the low point of the space.

The ground under Baltic

Baltic sits right on the Big Sioux, where the valley narrows and the underlying Sioux Quartzite comes close to the surface. Thin cover over fractured bedrock is one of the more reliable predictors of a high reading in eastern South Dakota.

Baltic radon questions

Will this fix my damp basement smell?

Often, largely, and within weeks. The smell is usually ground moisture evaporating into framing, and a sealed membrane stops that at the source rather than dehumidifying the result.

Do I still need a dehumidifier afterward?

Many people find they run it far less. Sealing the soil is the upstream fix, and the dehumidifier stops fighting a losing battle.
