Frequently asked questions
The lot is sand on a terrace. Why does water get under the slab instead of draining off?
Sand pipes it sideways. Marine-terrace sand carries winter water beneath the pad rather than letting it sink out of reach, so it travels under the slab and surfaces wherever the finish gives first. Good drainage in the top foot is not disposal.
The house is on The Bluffs. Is the bay still involved?
As tide, only at the toe. As a cut, yes. Terrace sand weeps the buried face after February, and that water is going to the bay whether the house is. The tide job is Upper Bay fill. The seepage job is the bluff cut.
Mesa Verde bakes from April to November. How is February still a moisture call?
February is a large share of a short wet season, and the covering has been baking since April. Terrace sand then pipes the first cell under the slab. A dry climate opens; the mesa then soaks through those openings all at once.
