DRAINAGE & EROSION CONTROL FOR MOUNTAIN PROPERTIES
Engineered drainage solutions built for Southwest Colorado mountain terrain. Spring runoff, steep slopes, freeze-thaw cycles, and variable soil conditions require drainage systems designed for the specific challenges this environment presents. We build them to last.
MOUNTAIN-TERRAIN DRAINAGE SPECIALISTS
Engineered Drainage Solutions, Durango, CO
No competitor in the Durango market writes about mountain-specific drainage challenges because most of them are not thinking about it at the level the work demands. Spring runoff that overwhelms standard drainage, frost heave that shifts structures, erosion on slopes that accelerates with each storm season. These are the real conditions mountain properties face, and they require drainage systems engineered for exactly this environment.
LandEx approaches every drainage project with precision grading as the foundation. Smart-grade technology ensures every surface drains at the correct slope, and every drainage structure is positioned where the water actually goes, not where a generic plan assumes it will. Twenty years of working in La Plata County mountain terrain means we have seen what works and what fails when the spring thaw arrives.

SURFACE DRAINAGE GRADING
Precision grading to establish proper surface drainage slopes across your entire property. Smart-grade technology ensures water moves away from structures, driveways, and vulnerable slopes. The foundation of every drainage system starts with correct grading.
FRENCH DRAINS & SUBSURFACE DRAINAGE
French drain installation, subsurface drainage systems, and foundation perimeter drains for properties where surface grading alone cannot solve the water management challenge. Properly sized, properly sloped, and built with the right materials for mountain-terrain conditions.
SWALES & DRAINAGE CHANNELS
Surface swales, rock-lined channels, and diversion berms to collect and redirect water flow away from structures and vulnerable areas. Designed for the water volumes that mountain properties actually see during spring runoff, not the volumes a flat-terrain spec assumes.
CULVERT INSTALLATION
Culvert sizing and installation for driveways, roads, and property crossings where water needs to pass under a surface. Properly sized culverts prevent upstream pooling and downstream erosion. We install them with precision placement and inlet/outlet protection.
SLOPE STABILIZATION
Slope stabilization using retaining walls, boulder placement, terracing, erosion blankets, and revegetation support. Critical for mountain properties where steep slopes, cut banks, and fill slopes are exposed to water and weather. Prevents progressive failure that worsens with each season.
EROSION REPAIR & RESTORATION
Repair of existing erosion damage including gully filling, slope regrading, drainage structure installation, and surface stabilization. We address the root cause, not just the visible damage, so the problem does not return with the next storm or spring thaw.
BUILT FOR MOUNTAIN CONDITIONS
Why Mountain Drainage Requires Specialists
SPRING RUNOFF VOLUMES
Southwest Colorado spring snowmelt delivers water volumes that standard drainage systems are not designed to handle. Drainage structures sized for rain events will be overwhelmed during spring runoff. Every drainage system we build is sized for the actual water volumes mountain properties experience, not the volumes a standard engineering table predicts.
FREEZE-THAW CYCLE STRESS
Durango sees over 100 freeze-thaw cycles per year. Each cycle stresses drainage structures, shifts soil, and can displace pipes and channels that were not installed with this specific stress in mind. Our drainage installations account for frost depth, heave potential, and the movement that mountain properties experience across seasons.
STEEP SLOPE WATER VELOCITY
Water moves faster on steep slopes. Faster water carries more soil. Standard erosion controls designed for gentle grades are inadequate on mountain terrain. We size channels, select rock, and design energy dissipation features specifically for the velocities that mountain slopes produce.
VARIABLE SOIL & ROCK CONDITIONS
Mountain properties often have multiple soil types and rock layers within a single drainage run. How water moves underground changes with each soil transition. Effective subsurface drainage requires understanding what the ground is actually doing, not assuming uniform conditions across the site.
