Groundwater & Basement Water Intrusion in Chandler, AZ
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
Why does every neighborhood have a sunken park?
Because development here is required to retain its own stormwater on site rather than discharge it. Those basins are the drainage design, holding runoff until it soaks away or evaporates, and there is generally no pipe taking it anywhere else. When one fills beyond its capacity the water has nowhere further to go.
Nine inches a year cannot be a problem.
The annual figure is close to meaningless here. A monsoon cell can deliver an inch in under an hour onto ground baked hard for months with a cemented caliche layer beneath it, so effectively none of it soaks in. A desert storm produces runoff that a much wetter climate would absorb.
What is caliche?
A naturally cemented layer of calcium carbonate that forms below the surface in arid soils, and here it is often within a few feet. It is close to impermeable, so water moving down stops at it and spreads sideways. It also makes excavation difficult, which is part of why nothing is built below grade.
