Foundation Conditions in Charlotte
Charlotte sits in the Piedmont on decomposed granite soils with a significant clay content. This weathered material (called saprolite) is unpredictable - its bearing capacity varies widely, and it can shrink and expand with moisture changes.
Charlotte's humid subtropical climate delivers significant annual rainfall. Intense summer storms and seasonal drought periods create the moisture cycling that saprolite soils handle poorly.
Common Foundation Types in Charlotte
Charlotte's fast growth has produced many homes on subdivided land with variable soil compaction. Crawlspace and slab construction are both common. Foundation repair demand is significant and well-served by a large contractor market.
Most Common Foundation Problems in Charlotte
- Saprolite settling and shrinkage
- Crawlspace moisture and rot
