Walkout construction on the sloped Tea lots produces split-level ground contact, where part of the lower level is a proper slab and part sits over crawl. That arrangement needs to be mapped before anybody prices a system, because one suction point placed in the wrong half leaves the other half untreated.

What we see in Tea

The sloped-lot subdivisions off Heritage Parkway are where this pattern repeats. Access is frequently through a small door in the lower-level wall rather than a floor hatch, which makes the membrane work easier than average since material can be carried in upright.

Practical notes for Tea homeowners

Sealed crawl spaces here also stop the cold-floor complaint people have about rooms above them. Nobody buys a radon system for warmer floors, but in a Tea walkout it is the part homeowners mention a year later.

Crawl Space Systems in Tea: the technical part

Split ground contact is the Tea pattern. On a sloped lot the lower level is slab at one end and crawl at the other, divided by a footing wall that suction will not cross. The two halves need separate pickups, and the giveaway that this was missed is a post-mitigation test that came back respectable but not good, typically somewhere between 3 and 5.

What the job looks like in Tea

We map the ground contact before pricing, with a test hole and a vacuum reading in each area. Where a crawl portion exists, the membrane goes down first and the suction points are set afterward, both joined into a single riser. On walkouts the crawl is frequently accessible through a proper door, which makes the material handling far easier than a hatch.

The ground under Tea

Tea sits west of the Big Sioux valley on flat glacial outwash and till, which drains well and moves soil gas laterally without much resistance. Good ground to build on, and good ground for radon to travel through.

Tea radon questions

Will sealing the crawl make my floors warmer?

Usually noticeably, in the rooms directly above it. You have taken a vented dirt space out of the thermal path, and in a South Dakota February that is worth something on its own.

Can I do the membrane myself and have you do the rest?

We would rather do the whole thing, because the seal detail at the wall and around the piers is what determines whether it works. A partial seal performs like no seal.
