Basement Waterproofing in Miami, FL

Basement Waterproofing in Miami: local conditions

Miami, FL sits on sandy soils over limestone and has a humid subtropical and tropical climate with about 54" of rain a year. The local water table is very high statewide, with no meaningful winter freeze–thaw, and slab-on-grade is near-universal and basements are essentially absent. In practical terms, a very high water table, heavy rain and sinkholes drive slab and drainage problems — which is exactly why basement waterproofing is a common need here.
