Groundwater & Basement Water Intrusion in Rancho Cucamonga, 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 above the city for?
They catch the rock and soil that comes out of the canyons during a storm, so that the water reaching the streets is water rather than a moving mass of material. They work by filling up, which means their capacity has to be restored between events. A basin that has not been cleared out has less room than it was designed with, and that is a fair question to ask about.
The slopes above burned. How long does that last?
Several years rather than one season. Burned ground sheds water instead of absorbing it and carries soil and ash with it, so a storm that would previously have passed unnoticed can produce a flow of material. The elevated risk persists while vegetation returns. A property below a recent burn needs a different plan from the one it needed the year before.
The ground drains very well. Is that not enough?
It is excellent for ordinary rain and beside the point for the risk that matters here. Fan material is coarse and takes water readily, which is why standing water is rare, but that same material is the record of the canyon depositing it. The hazard is about what occasionally comes down the channel rather than what soaks in daily, and good drainage does nothing about the first.
