Groundwater & Basement Water Intrusion in Thornton, CO
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
The house is new. Should the foundation not cope with this soil?
It is designed against it, on the assumption that water is being kept away from the ground beside it. That assumption is the weak part rather than the concrete. Downspouts discharging at the wall, a grade that has settled back toward the house, and irrigation running against the foundation all undo the design without anything visibly failing.
The patio and the drive have lifted rather than sunk.
This ground gains volume as it takes on water and pushes upward on whatever is bearing on it, which is the opposite of what most people expect from foundation trouble. Flatwork poured on it moves first because it has nothing holding it down. The cause is water reaching the soil rather than any load above it.
The lawn is watered daily through the summer.
On soil that swells, that is a larger input than the rain is. Fifteen inches falls from the sky in a year here and a sprinkler system can put more than that against a foundation over one summer, evenly and repeatedly. Moving the heads back from the wall, and shortening the runs nearest it, costs nothing and changes what the ground is doing.
