Groundwater & Basement Water Intrusion in Lone Tree, 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 handle this soil?
It is designed for it, and the design assumes the drainage around it is doing its part. Modern foundations here are built to tolerate a soil that expands, on the basis that the ground beside them is kept at a reasonably steady moisture level. Where roof discharge, irrigation or grading puts water against that soil, the design is being asked to do something it was not built for.
The slab downstairs has broken upward.
What has happened is heave rather than settlement, and it is the signature failure on ground like this. The soil takes on moisture, gains volume with real force and lifts whatever is resting on it. The water reached it from the surface almost every time, so the correction is outdoors: discharge carried clear, sprinklers pulled back, ground pitched away.
How much is the sprinkler system contributing to this?
A good deal more than owners expect, because it operates all summer somewhere that would otherwise be arid. A zone watering beds against the wall is delivering moisture on a timer to exactly the soil that ought to be held steady. Pulling heads back from the building and keeping planting a few feet off it costs almost nothing and it is one of the few interventions that reliably works here.
