Drainage & French Drains

Drainage Solutions for Oregon Properties

Water management is critical in Oregon's wet climate. Standing water, soggy yards, and wet basements are common problems that proper drainage can solve. Cojo Excavation & Asphalt designs and installs drainage systems throughout Oregon that protect your property from water damage.

### Common Drainage Problems We Solve

**Wet Basements & Crawl Spaces** Water infiltrating foundations damages structures and creates mold issues. We install perimeter drains that collect and redirect water before it enters your home.

**Standing Water in Yards** Low spots that collect water create mosquito breeding grounds and kill grass. French drains and swales redirect water to appropriate outlets.

**Soggy Areas** Persistently wet areas indicate poor natural drainage. We regrade and install drainage to create usable yard space.

**Erosion** Uncontrolled runoff erodes landscaping and undermines structures. Proper drainage channels and controls protect your property.

### Our Drainage Solutions

• Foundation perimeter drainage
• Yard drainage
• Retaining wall drainage
• Crawl space drainage

**Surface Drains** Catch basins and channel drains that collect surface water from patios, driveways, and low areas. Connected to underground piping that carries water to outlets.

**Grading & Swales** Sometimes the best solution is reshaping the land. We create grades and swales that direct water away from structures using natural gravity flow.

**Dry Wells** Underground chambers that collect water and allow it to slowly percolate into the soil. Used where there's no good outlet for drainage piping.

**Sump Pump Systems** When gravity drainage isn't possible, sump pumps actively move water away from your foundation.
