This paper addresses the feasibility of using permeable low-density cellular concrete (PLDCC) in soft soil remediation applications. In discussing this feasibility, the paper will review and evaluate data from recent studies conducted at the University of Missouri Kansas City related to the physical properties of PLDCC, including permeability, infiltration, and void structure. This paper will cover the most typical applications for the utilization of PLDCC and take a brief look at the constructability and cost considerations. Three specific case studies are examined, including a wall abutment project in Bellingham, WA, a structural foundation project in New Orleans, LA, and a sinkhole remediation project in Chester County, PA. All three of these case studies utilized 25 to 35 pcf (pounds per cubic foot) (400 kg/m3 to 560 kg/m3) PLDCC for soft soil remediation.
