Basement waterproofing in Denver, CO

Denver sits at the western edge of the Great Plains below the Rockies. Its dry climate hides a serious basement issue: expansive clay and claystone that swell when wet, lifting floors and pushing walls, plus snowmelt that floods window wells.

What kind of homes and basements does Denver have?

Washington Park, Park Hill and Highland have early 20th-century homes with brick foundations and full basements; postwar bungalows and ranches dominate many other neighborhoods. Window wells are common on basement living spaces.

What causes basement and foundation problems in Denver?

Swelling soil heave

Expansive clays lift slabs and push walls when they get wet; keeping water away from the foundation matters most.

Window-well flooding

Snowmelt and storms fill window wells and leak through windows into finished basements.

Older brick foundations

Brick foundations in historic neighborhoods need compatible repairs and drainage.

Floating basement floors

Some Front Range homes have 'floating' basement slabs with gaps at the walls to allow soil movement. Interior walls in finished basements should also allow for movement, or they can crack as the slab heaves.
