Groundwater & Basement Water Intrusion in San Diego, CA
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
Nothing anyone says about this city seems to apply here.
That is a fair complaint in a place this large. The ground runs from coastal terrace to mesa top to canyon rim within a few miles, and a remedy matched to one is frequently wrong for another. Establishing what is actually under a particular lot, with a couple of test holes, comes before deciding what to spend anything on.
The house sits on a pad cut into a canyon rim.
Where the original ground ran decides it, and on a canyon rim that line falls in a different place on every lot. One pad may sit almost entirely on undisturbed ground while its neighbor is mostly on placed fill. The grading plan filed when the tract went in shows exactly where the boundary lies.
The canyon below the house fills within the hour.
Canyons here gather from a wide area of mesa top that is largely roof and pavement, so rain reaches the bottom within minutes rather than working through soil over hours. The level spikes and drops inside a single storm. For a property on the rim, whatever is going to be done has to have been decided in advance.
