How to Fix Sinkholes. Sinkholes develop when soft rock underground—e.g., limestone, gypsum, or other carbonate rock—wears away over time. This is known as "karst" terrain. Eventually, the unsupported sediment above the underground hole col...


Water from broken pipe can penetrate through mud and rocks and erode the ground underneath and cause sinkholes. Sometimes, heavy weight on soft soil can result in collapse of ground, resulting in a sinkhole. Sinkholes can also form when the land surface is changed.
