Drainage Problems on Clay Soil: McKinney Solutions Guide

Drainage Problems and Clay Soil in McKinney

McKinney sits on some of the most challenging clay soil in North Texas. This expansive soil absorbs water and swells, then shrinks and cracks during dry spells. Poor drainage accelerates this cycle and puts your foundation at serious risk. Understanding your options helps you protect your home before damage starts.

French Drains

A perforated pipe installed in a gravel-filled trench that redirects subsurface water away from your foundation. French drains are the most popular drainage solution in Collin County and work well along fence lines and around home perimeters.

Grading Corrections

The ground should slope away from your foundation at a minimum of six inches over ten feet. Over time, McKinney clay soil settles unevenly and can reverse this slope, channeling rainwater directly toward your slab.

Channel and Surface Drains

• Channel drains: Linear grates installed in driveways or patios to catch sheet flow before it pools against walls.
• Catch basins: Collect water from downspouts and yard low spots, routing it to the street or a dry well.

Preventing Foundation Damage

Standing water against your slab is the number one cause of foundation movement in McKinney. Pairing proper drainage with well-maintained concrete flatwork keeps water moving away from your home and protects your investment for years to come.
