Groundwater & Basement Water Intrusion in Clovis, 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 is hardpan and why does it matter?
It is a naturally cemented layer that forms a few feet below the surface in valley soils like these, and it is effectively impermeable. Water moves down through the topsoil, reaches it, and then has to spread sideways because it cannot continue down. That produces saturated ground at shallow depth on a site whose surface appears to drain well.
There is a canal running near the property.
Those are operated for irrigation delivery on a schedule set by the water district, so they carry water at times that have nothing to do with rainfall. A canal running full in summer keeps the ground beside it wet during the months everything else is dry. The district publishes its delivery schedules.
It does not rain here between May and October.
Which means the ground has been baking for half the year when the first storm arrives, and a sun-hardened surface sheds water rather than taking it. The opening storms of the season therefore produce more runoff than their size suggests. Infiltration improves once the profile has wetted, usually several storms in.
