Colorado Springs sits in a semi-arid high-plains climate where hot summers give way to cold winters that drive repeated freeze-thaw cycles. These cycles push moisture into foundations and then expand it, especially on the older stone and early concrete foundations common in Old Colorado City and Manitou Springs. Homes in Broadmoor and Rockrimmon often sit on sloped lots that channel snowmelt or heavy summer rain toward the footing, creating hydrostatic pressure that interior-only fixes rarely stop.
Exterior waterproofing begins with excavation to the footing, followed by cleaning, crack repair, and application of a fluid-applied membrane or dimpled drainage mat. In El Paso County, any work that changes grading or drainage must respect local setback and stormwater rules, so we document elevations before and after. Interior approaches such as perimeter drains tied to a sump become necessary when excavation is blocked by utilities or mature landscaping near Cheyenne Mountain properties.
Ignoring small seepage in neighborhoods like Briargate or near the United States Air Force Academy often leads to efflorescence and eventual structural movement once winter temperatures drop. We always inspect soil conditions at the footing and note whether clay lenses or sandy fill are present, because each requires different drainage details. Homeowners in nearby Security-Widefield or Fountain face similar issues on flatter lots where water pools rather than runs off.
Technician insight
In Colorado Springs, the thing that catches most people out with Foundation Waterproofing is how quickly a small crack in an Old Colorado City or Manitou Springs stone foundation widens after one hard freeze because the high-plains soil holds just enough moisture to expand against the wall.
Broadmoor Home With Recurring Seepage
A 1960s home on a sloped lot near Cheyenne Mountain showed dampness along the north wall each spring. Excavation revealed no membrane and poor original grading that funneled snowmelt to the footing. We installed a dimpled mat and exterior drain tied to a new sump, then re-graded the yard. The basement stayed dry through the following winter.
Foundation Waterproofing Services We Offer
✓Exterior Foundation Membrane Application
Full excavation and application of fluid-applied or sheet membranes on the exterior wall to stop water at the source before it reaches living space.
✓Interior Perimeter Drain Installation
Trenching inside the basement to install a French drain system that collects water and directs it to a sump pump, useful when exterior access is limited.
✓Foundation Crack Injection
Epoxy or polyurethane injection into active cracks to restore structural integrity and stop seepage in older Broadmoor and Manitou Springs homes.
✓Sump Pump and Battery Backup Systems
Installation or upgrade of primary and backup sump pumps sized for Colorado Springs storm volumes and tied into existing interior drainage.
✓Grading and Downspout Correction
Re-sloping soil away from the foundation and extending downspouts to prevent surface water from collecting against the wall in sloped lots near Garden of the Gods.

How it works
- 1
On-Site Assessment
We examine both interior and exterior conditions, note foundation type, soil exposure, and drainage patterns around the specific property in Colorado Springs.
- 2
Excavation Or Interior Prep
Exterior walls are exposed to the footing where possible; interior jobs involve removing flooring and trenching along the perimeter.
- 3
Membrane And Drainage Work
Cracks are repaired, waterproofing membrane or drain tile is installed, and water is directed to a reliable discharge point.
- 4
Backfill, Grading, And Testing
Soil is replaced with proper compaction, final grading directs water away, and the system is tested with controlled water flow.
Pricing
Costs depend on foundation depth, access, and whether exterior excavation or interior-only work is chosen; we provide written quotes after the site visit.
