Groundwater & Basement Water Intrusion in Lake Havasu City, 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
Water came off the slope above and through our property.
On terraced desert slopes that is the standard mechanism. Ground here absorbs very little, so a short intense cell produces runoff almost immediately, and the terracing that made the lots buildable also decides where it concentrates. Interception above the house, with a diversion that carries flow past rather than into it, addresses it at the source. Work done at the wall itself is fighting the water at the worst possible point.
An inch of rain a month cannot be dangerous.
The monthly figure hides how it arrives and what the ground does with it. Rain here comes in short intense bursts onto rock and decomposed granite that absorb almost nothing, so runoff happens at close to the full rainfall rate and the slopes deliver it downhill within minutes. Annual totals describe how little rain falls; they say nothing about what happens to the rain that does.
In a place this dry, what causes most interior water damage?
Plumbing and appliances, by a wide margin. Supply lines, water heaters, and appliance connections account for most interior water in a desert climate, and slab construction means the water travels under the floor and surfaces late, often away from the break. Knowing where the main shutoff is, and replacing a water heater at the end of its service life rather than after it fails, addresses most of the realistic risk.
