Groundwater & Basement Water Intrusion in Tempe, 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
Something on the roof is the source rather than the roof itself.
On older stock here that is common, because coolers, condensers and water lines were routinely put up there. A supply line or a pan that fails on a roof empties directly into the ceiling below, and it can run for a long time before anything shows. Anything on a roof that holds or carries water is worth looking at each spring, before the season it will be run hardest in.
The river is dry upstream and there is a lake through town.
The lake is held in the channel by structures at each end and it is managed rather than natural. Upstream and downstream of it the bed is dry most of the year, as it has always been. What matters for a property near the channel is that the bed is still a river course: it carries water when there is water to carry, and that is a different event from the lake being there.
Twenty minutes of rain and the street was a river.
Monsoon cells deliver a large fraction of the annual total in under an hour onto ground with caliche near the surface that absorbs essentially nothing. Everything that lands runs, and the street is the channel because nothing else is. The volume is genuinely small; the rate is what causes the damage, and systems sized around annual figures were never sized for that hour.
