Groundwater & Basement Water Intrusion in Greenwood Village, 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 basement slab has cracked and risen.
That is the characteristic failure on this soil, and it is heave rather than settlement. Claystone takes on water and expands with real force, pushing the slab upward from beneath. Almost always the water got there from the surface: roof discharge too close to the wall, irrigation against the foundation, or ground that falls toward the building. The remedy sits outside rather than in the concrete.
How much does landscape irrigation contribute?
More than most owners expect, because it runs all summer in a place that would otherwise be dry. A system watering beds against the house delivers water to exactly the soil that should stay at a steady moisture level, and it does so on a schedule rather than occasionally. Moving heads away from the foundation and keeping beds a few feet off the wall is cheap and it matters here.
There is a dam upstream. Does that settle the flood question?
For the main channel, largely; for everything else, no. A flood-control structure addresses the river it sits on and does nothing about a storm that falls below it, about street drainage at capacity, or about water arriving at a foundation from a lawn. Most of what damages houses here is local rather than riverine, and the structure upstream is not aimed at it.
