Lewisville's post-1990s subdivisions around Lewisville Lake sit on clay soils that hold water from the reservoir and from sudden deluges along I-35E and TX-121. Homeowners in Old Town and near Vista Ridge Mall routinely see seepage after the severe storms that hit Denton County each spring and fall. Perimeter systems here run deeper trenches with larger aggregate to intercept both groundwater and surface sheet flow before it reaches foundations.
Perimeter Drain Systems in Lewisville — What We Handle
- ✓Lake proximity creates steady hydrostatic pressure absent in drier inland suburbs.
- ✓Rapid growth left many 1990s-2000s homes with undersized or nonexistent perimeter lines.
- ✓Clay soils and frequent downpours demand larger pipe and more precise grading than standard installs.
Plano sits on heavy clay soils that expand and contract with the area's hot summers and sudden severe storms, pushing water against foundations in neighborhoods like Willow Bend and Legacy West. Perimeter drain systems intercept this flow before it reaches basements or slabs by using perforated pipe set in gravel beds wrapped with filter fabric. In Collin County homes built before the 1990s, especially in Downtown Plano and East Plano, older footings often lack any drainage, so retrofits must tie into existing grading without disturbing mature landscaping or nearby utilities.
Installation begins with locating irrigation lines and gas mains common in West Plano subdivisions, then excavating a trench that slopes consistently toward a daylight outlet or sump. Pipe diameter and gravel depth are chosen based on roof square footage and the frequency of intense rainfall that overwhelms yards near Oak Point Park. Homeowners in Frisco and Richardson often request extensions that connect perimeter lines to street storm inlets when lot drainage is restricted by retaining walls or patios.

✓Foundation Perimeter Drains
Installs a continuous loop of perforated pipe and gravel around the entire foundation to intercept water before it reaches slabs in clay soils typical of West Plano.

✓Driveway Edge Drains
Places shallow perimeter drains along driveways and sidewalks to stop water from pooling against garage slabs in East Plano neighborhoods.
✓Retaining Wall Drainage
Weaves perforated pipe behind retaining walls to relieve hydrostatic pressure on sloped lots near Oak Point Park and Downtown Plano.
