Functionality Mistakes Throughout History That Were Way Too Expensive to Fix

In 2020, a series of homes in South Dakota, built over an abandoned Dakota Plaster Company mine, faced a crisis with damage estimates between $10-15 million. Homebuyers unaware of the risky foundation saw their investments crumble as the story gained national attention.

A dramatic event unfolded as a homeowner narrowly escaped a sinkhole, prompting the evacuation of twelve families. Below the community lay a 600-foot-long forgotten gypsum mine, devaluing the properties to worthlessness. This incident underlines the critical importance of geological assessments in residential areas.
