Can sinkholes be repaired?
Not without spending a great deal of money. In some cases, dumping rocks into a sinkhole can mitigate the problem, but this is likely just a temporary fix as the sinkhole will usually open up again. This is because most sinkholes actually have multiple holes downward as well as openings sideways between rock beds. They resemble a cook’s colander. When site engineers, consultants, and contractors are not aware of sinkhole dangers—and do not account for these hazards in their design and construction—the result will be facilities and structures that might crack, collapse, and fail. Any repair and replacement costs would be high; we could end up paying for the facility twice.
