Groundwater & Basement Water Intrusion in Norman, OK
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
Sand at one end of the city and clay at the other.
That is the situation and it means a remedy matched to one is frequently wrong for the other. On the sand beside the river water arrives from beneath and moves quickly; on the clay it sits on the surface and moves the building. Two test holes on the actual lot settle which case applies, and doing that first avoids paying for the wrong work.
The roof looks fine from the ground after a hailstorm.
It usually does, because hail damage is visible on the surface of a covering rather than from below. The point that costs people money is timing: the clock for reporting runs from the date of the storm, not from the day a leak appears months later. Getting someone onto the roof within days of significant hail is what keeps the two connected.
How much does the level under the sand move?
A good deal, and it follows the river closely. Sand of that kind passes a rise sideways very efficiently, so what the channel does out there becomes what the ground does underfoot within a day or so. That is why a basement well back from the bank can take water while nothing has overtopped anything at all.
