Ground conditions
Some Colorado soil swells when it gets wet.
Expansive clay and claystone bedrock are common along the Front Range. They swell as they take on water and shrink as they dry, enough to crack slabs and lift foundations. A soils report from a geotechnical engineer tells the foundation designer what's actually under the lot.
