How big are sinkholes?
Most sinkholes are 10 to 12 feet in diameter. A discussion of foundation repair methods such as driven piers, helical piers, or other structural repair methods may seem in order, but if a sink hole is big enough to swallow a home, the first order of business for areas where those problem soils are found (California sinkholes, Florida sinkholes, Pennsylvania sinholes over mines, Texas sinkholes, often over salt domes and possibly affected by wastewater disposal back into the ground during oil drilling, others) is to recognize the signs that sinkholes have plagued a neighborhood and/or that a sinkhole is presently developing at a particular home. Sinkholes hundreds of feet in diameter have occurred in Florida and Texas – big enough to swallow a home. The “December Giant” sinkhole in Montevallo, Alabama was 520 x 125′ and 60′ deep. The Dasietta Texas sinkhole reached 525′ x 600′ and a depth of 150′, collapsing an aera of roughly 1/10 of a square mile within two days of its first appearanc
