Stabilization and Repair of Concrete Slabs-on-Ground Deformed by Expansive Soils

摘要

Concrete slabs-on-ground foundation systems may be subject to detrimental deformation due to upward thrust from expansive soils. These deformed slab foundations have traditionally been repaired using methods seeking to overcome the soils' expansive forces through structural means or by complete removal and replacement. A more cost-effective solution may be reached through the installation of vertical and/or horizontal barriers that re-establish points of origin for moisture intrusion, redefine slab design parameters and stabilize the soil moisture content under the slabs, neutralizing the potential for further deformation.
