Your McLean waterproofing and foundation specialists
McLean's larger lots and mature tree canopy sit on Piedmont uplands cut by streams like Scotts Run and Pimmit Run. Big homes on sloping, wooded ground face a specific challenge: a lot of roof and surface water with a lot of clay underneath to keep it around.
McLean's soils and terrain
McLean rests on clay-rich Piedmont saprolite over crystalline bedrock. On the area's wooded slopes, runoff concentrates as it moves downhill toward the Potomac tributaries, and the dense clay subsoil holds that moisture against foundations and in crawl spaces long after the rain stops.
Common crawl space & foundation problems in McLean
McLean's homes — from mid-century estates to large new builds — often have expansive footprints, finished basements, and substantial roof areas. That means high volumes of roof water, finished lower levels that can't tolerate dampness, and clay soils that swell and stress foundations seasonally.
- High roof-water volume on large homes
- Runoff concentrating on wooded slopes
- Finished basements vulnerable to seepage
- Crawl space humidity under expansive footprints
- Seasonal foundation movement in clay soils
