Groundwater & Basement Water Intrusion in Lancaster, 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
Seven inches a year and there is a flooding concern?
The total is almost irrelevant to how this ground behaves. Desert soil develops a hard surface crust that sheds water, and there are no established channels to carry it, so an ordinary winter storm spreads out across the valley floor in a broad shallow sheet. Two inches on this ground moves further than considerably more would in a wetter climate.
What is an alluvial fan in practical terms?
It is the spread of material laid down where a canyon empties onto flat ground, and the water follows the same pattern. Instead of staying in one channel, flow fans out across a broad apron and can take a different path in each storm. A property on a fan may be dry for many years and then find itself in the active route.
The dry lake only has water in it occasionally.
It is the low point of a closed basin, so what reaches it stays until it evaporates. In a wet winter it holds water across a wide area for weeks, and the extent varies a great deal between years. Its normal dry appearance is a poor guide to how far it reaches in an unusual season.
