A Case History of Pile Foundation Remediation for Karst Activity
This paper discusses the case history of mitigating karst conditions during construction of a bridge foundation in central Florida. The installation of a test pile triggered the initial sinkhole and subsequent operations such as drilling test borings and grout injection triggered additional sinkholes. Sinkhole formation at the site ceased only after a substantial quantity of grout was injected. Discovery of active sinkhole conditions during construction required a proactive approach to minimize construction delays and associated costs. Additional investigations were performed to better understand the extents of the problem in order to develop cost effective solutions. The available information indicated that karst subsurface conditions consisted of a cavity dome above the bedrock, below the anticipated pile tip elevations. After considering various remediation options a grouting program was implemented to fill the voids and densify raveled soils below the anticipated pile tip elevations.
