Groundwater & Basement Water Intrusion in Riverside, 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
That wide sandy channel is dry. Is it still a river?
It is a river with the water underground for most of the year, and the mapping treats it that way. A wide sandy bed carries an enormous flow when the mountains upstream shed one, and because the bed is loose the channel shifts within it between events. The dry sand is where the water goes, not evidence that it does not come.
There are old irrigation works crossing this property.
Ditches, buried pipe and concrete channels from the citrus era run across a great many lots here, some abandoned and some still carrying water for somebody. They collapse, they leak, and they turn up in places no current plan shows. Finding out what crosses a lot, and whether anything still runs in it, is worth doing before digging anywhere.
The soil is sandy and the water still stands on it.
A long dry season bakes a crust onto bare soil that sheds water almost completely regardless of what lies beneath, so the first storms run off ground that would absorb them readily in March. It is a surface condition rather than a drainage one, and breaking the crust or keeping something growing on it is what changes the behavior.
