Building on Sinkholes

Hundreds of sinkholes occur each year in many parts of the United States, causing significant property losses. Great potential exists for casualties unless measures are taken to minimize groundwater depletion and the increases in surface water infiltration that precipitate sinkholes. George Sowers examines the mechanisms of sinkhole formation in limestone (or karst terrain), methods for overcoming sinkhole-related failures, and techniques to avoid or minimize future sinkhole collapses. For new projects being planned, designed, and constructed, he identifies the most effective ways to prevent sinkhole problems in areas prone to sinkhole development.
