Groundwater & Basement Water Intrusion in Fontana, 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
What are the basins at the foot of the mountains for?
They catch the rock, gravel and timber that a storm brings off the range, so that the water continuing downstream is carrying much less. They work well and they fill up, and a basin holding a season of material has far less capacity than its design. Their condition after a wet winter matters as much as their existence.
There is no creek anywhere near this property.
On fan ground a great deal of the water does not travel in a creek. It spreads across a broad apron in shallow sheets that follow very small differences in grade, and the path shifts between storms. A road embankment or a new wall can redirect it substantially, so the absence of a channel is not the reassurance it appears to be.
A dry year here still ends in a wet fortnight.
The annual figure describes none of the days that matter. A single winter system against this range can deliver a large share of the year in a day, onto slopes with almost no soil to absorb it. What arrives at the bottom is decided by intensity and by what the mountain is carrying, not by the yearly total.
