This paper addresses the causative factors associated with curling of concrete slabs poured on grade. The study was initiated when the owner of a newly constructed warehouse brought legal action against the designer/contractor for excessive concrete slab curling. Subsequent to settling with the owner, the designer/contractor brought legal action against the subcontractors who prepared the subgrade and placed the concrete. A computer model was developed by the defendant’s expert to evaluate the effect selected parameters have on curling of the concrete slab on grade. The parametric study was used to evaluate the most probable causes of the curling, which led to settlement of the case.
