Fix standing water, erosion, and runoff issues in Castle Rock, Parker, and Castle Pines — targeted drainage solutions that protect your property and landscape.
Water problems don't fix themselves — they get worse. Standing water kills plants, erodes soil, damages hardscape, and can threaten your home's foundation. If you have drainage issues, they need to be addressed before they cause expensive, irreversible damage.
Ground Theory diagnoses and corrects drainage problems with targeted solutions. We identify where water comes from, where it pools, and where it needs to go — then implement fixes that are both effective and unobtrusive.
From regrading to French drains to dry creek beds, we solve water problems at their source — protecting your property and your peace of mind.

Comprehensive evaluation of water flow patterns, problem areas, and the root cause of your drainage issues.
Regrading to redirect surface water away from structures and toward appropriate drainage paths.
Subsurface drainage systems that collect and redirect groundwater away from foundations and problem areas.
Beautiful, functional rock-lined channels that manage water flow during storms while adding landscape character.
Surface drainage collection for persistent standing water in lawns, driveways, and low-lying areas.
Underground piping and extensions to direct roof water away from your foundation.
Drainage problems worsen over time. Every storm erodes a little more soil, saturates a little more ground, and undermines a little more of your landscape and hardscape. What starts as a minor nuisance can become a major — and expensive — problem. Early intervention is always less costly.
Ground Theory proudly provides drainage corrections services to homeowners and commercial properties across the southern Denver metro and Front Range communities.
Signs include standing water that persists more than 24 hours after rain, erosion or gullies on slopes, water in your basement or crawl space, dying plants in low areas, soil splashed on your foundation, or ice patches in winter. If you notice any of these in Castle Rock or Parker, a drainage assessment is warranted.
The most common issues are downspout water pooling near foundations, negative grading toward the house (settling over time), and clay soil that drains poorly. These create saturated zones that damage foundations, kill plants, and breed mosquitoes. Fortunately, they're also the most straightforward to fix.
Absolutely. We design drainage features that manage water effectively while enhancing your landscape. Dry creek beds with river rock and boulders, bioswales with native plants, and natural stone channel ways are all functional drainage solutions that add visual interest to your property.
