Your Ashburn waterproofing and foundation specialists
Ashburn grew explosively in the 1990s and 2000s, and much of that construction sits on Loudoun County's well-known shrink-swell 'marine clay' soils. Newer homes are not immune — these soils are aggressive enough to stress even recent foundations, which is why Ashburn sees so many drainage and settlement concerns.
Ashburn's Loudoun marine clays
Ashburn sits on Triassic basin soils that include highly expansive marine and lacustrine clays, locally infamous for shrink-swell behavior. These clays expand forcefully when wet and pull away as they dry, creating movement that newer subdivisions built on graded fill feel acutely.
Common crawl space & foundation problems in Ashburn
Because so much of Ashburn is recent construction on engineered fill over expansive clay, common issues include settlement of patios and stoops, foundation cracking, sump pumps that run constantly, and damp basements where the surrounding clay traps water against the walls.
- Shrink-swell movement from Loudoun marine clay
- Settlement of stoops, patios, and garage slabs
