Groundwater & Basement Water Intrusion in Santa Clara, 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
The yard drains fine most winters. Why did it flood this time?
On ground this flat, drainage depends entirely on a path staying open. A swale that has been planted over, a raised patio, or an inlet that silted up during the dry season can remove the lot's only route out without anyone noticing. The system then works until a storm exceeds what the remaining path can carry. Walking the lot during rain, rather than after it, usually shows exactly where the water stopped moving.
Water came through the wall we share with the next unit. Whose problem is that?
Practically speaking, it is both units' problem and it needs to be treated as one job. Water crossing a party wall wets framing and insulation on both sides, and drying only the visible side leaves a wet cavity behind the shared assembly. Access from both units, with meter readings taken in each, is the only way to confirm the wall is dry. The ownership question can be settled afterward; the drying cannot wait for it.
How do we find a leak under a slab without tearing up the floor?
By narrowing it before opening anything. A pressure test on the supply lines confirms there is a loss and separates hot from cold. Acoustic and thermal locating then puts the break within a small area. Only after that does concrete get opened, and it should be one access rather than an exploratory trench. Skipping the locate step is what turns a one-day repair into a week of demolition.
