Groundwater & Basement Water Intrusion in Chula Vista, 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
Eleven inches a year is nothing.
As an annual figure it is very little, and as a description of any actual day here it is misleading. The distribution is what matters: a single atmospheric river can deliver a quarter of the yearly total between morning and night. Damage tracks the intensity of one storm, not the sum of twelve months.
The ground is dry and hard most of the year.
Which is part of the mechanism rather than a protection against it. Soil that has been baking since spring takes water poorly at first, so the opening hour of a storm runs off a surface behaving more like pavement than earth. Infiltration improves once it is wet, by which point the peak has usually passed.
Should a burn upslope change anything down here?
It changes the timing and what the water carries. Ground stripped of cover sheds faster and brings ash and debris that block the inlets built to take the flow. That combination puts water where the drainage maps say it should not go, and the effect persists for a season or two rather than a single storm.
