Drainage & Erosion Control

Water problems on your property — whether it's a soggy yard that never dries out, a wet crawlspace after every rain, water pooling against your foundation, or slopes washing away — almost always come down to drainage. Coob's Landscaping diagnoses and corrects drainage issues throughout Chapel Hill, Durham, Carrboro, and the greater Triangle area.

The Triangle's Piedmont clay soil is notoriously slow to drain. Water moves across the surface rather than soaking in, concentrating in low points, against foundations, and in crawlspaces. After heavy rains, yards can stay saturated for days — killing grass, eroding topsoil, and putting structural pressure on your home's foundation and crawlspace walls.

We address drainage problems at the source rather than masking symptoms. Corby evaluates your property's grading, soil conditions, and water flow patterns before recommending a solution — because the right fix depends entirely on where the water is coming from and where it needs to go.

Common drainage problems we solve:

• Wet crawlspaces — Water entering crawlspaces from poor grading or surface water infiltration near the foundation
• Soggy yards — Low spots and clay soil that hold standing water long after rain
• Foundation drainage issues — Water pooling against the house due to negative grade or blocked drainage paths
• Downhill drainage — Water flowing from uphill neighbors or from impervious surfaces onto your property
• Downspout discharge — Concentrated roof runoff eroding beds or pooling near the foundation
• Eroding slopes and banks — Bare soil or turf washing away on grades that can't handle runoff velocity
• Driveway and culvert washouts — Water undermining gravel driveways or blocked culverts causing overflow

Our drainage and erosion control solutions include:

• Positive grading — Regrading the ground around your home so water flows away from the foundation rather than toward it
• Water diversion and berms — Reshaping the landscape to redirect water flow away from problem areas
• French drains — Perforated pipe in gravel-filled trenches to intercept and carry subsurface water
• Dry creek beds — Natural stone channels that move surface water while adding landscape value
• Downspout drainage — Burying downspout extensions to carry roof runoff safely away from the foundation
• Culvert pipe installation — Installing or replacing culverts under driveways and at drainage crossings
• Crawlspace waterproofing grading — Correcting exterior grade to reduce moisture infiltration into crawlspaces
• Erosion control on slopes — Combining proper grading, vegetation, and structural elements to stabilize eroding areas

Many drainage problems in the Triangle are made worse by construction — new neighbors, additions, or driveway changes that alter how water flows across the landscape. Whatever the source, Coob's has the grading equipment and experience to redirect water where it belongs and protect your property from the damage that comes with poor drainage.
