Foundation failure
is regional.
A slab in Houston fails for a different reason than a slab in Tampa, Denver or Tucson. The soil, the rock below it and the water moving through it decide how a building moves and what a real repair has to reach. Start with the ground you live on.
Florida Karst
Limestone dissolving under sand and clay. Sinkholes, raveling and cover collapse.
Read the region →Texas & Gulf Coast Clays
Expansive clays that swell when wet and shrink in drought, lifting and dropping slabs.
Read the region →Front Range Bentonite
Some of the most aggressive swelling soils in North America, along the Rockies.
In developmentArizona & Desert Southwest
Collapsible soils, caliche and earth fissures. Dry ground that holds until water reaches it.
Read the region →Pacific Coast
Saturated sands and bay fill that lose strength when the ground shakes.
In developmentPacific Northwest
Steep slopes, heavy rain and glacial deposits. Landslides and creep.
In developmentMidwest Frost & Loess
Frost heave, wind blown silt and basement walls pushed in by saturated soil.
In developmentThe World
Mexico City, Jakarta, Venice, Pisa, Christchurch. Cities built on ground that moves.
