Companies shell out $10,000 to $20,000 for a geotechnical and subsurface investigation before construction.The process isn't necessarily feasible for everyday people.However, a Western Kentucky University Geotechnical Engineer developed a device to detect what's happening beneath your feet.Karst terrain covers more than half of Kentucky. Karst sinkholes form when the bedrock of the Earth is slowly worn away by erosion.[SLIDESHOW: How karst sinkholes form]Under the top soil is a layer called the overburden. Under that is bedrock, which may seem tough and solid, but it's actually filled with cracks and crevices water is constantly seeping through and infiltrating. As the water erodes the bedrock, the overburden starts to fall down into the space left behind. Years later, all that's left is a thin layer and the potential for a sinkhole to open up.However, if there's a slab over the surface you may not know there's a problem until it's too late. That's why Matt Dettman developed MSEDS, short for Mechanical Sinkhole Early Detection System. Dettman is a WKU Associate Professor of Civil Engineering [...]
