Groundwater & Basement Water Intrusion in Greeley, 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 floor has lifted rather than sunk.
That is the soil swelling, which is the characteristic failure on this ground and the opposite of what people expect. Claystone takes on water and expands with real force, pushing a slab upward and cracking it from beneath. The cause is water reaching the soil under the house, so the remedy sits upstream of the concrete: roof water carried well away, no irrigation against the wall, and the ground falling away from the building.
The ditch runs all summer and the crawl is wet in July.
Those are connected more often than not. A ditch carrying water for months raises the level in the ground alongside it, and that reaches further than the bank suggests. It is also seasonal in a way rainfall is not, so wet ground in July and dry ground in November is the signature. The ditch company can say when it runs, and matching that against when the wet appears settles it quickly.
Fourteen inches a year and there was still a flood.
The average describes an ordinary year and says nothing about the exception. A storm that parks against the foothills can put down a large fraction of the annual total across several days onto ground that normally never sees it, and the channels here were shaped by ordinary years. That is why the flood history of this area looks so unlike its rainfall figure.
