24/7 Subsidence Monitoring
The world’s first and only sinkhole monitoring system for commercial and residential use.
About Florida’s Subsidence Epidemic
According to the US Geologic Survey, Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, spaces and caverns develop underground. Sinkholes are dramatic because the land usually stays intact for a while until the underground spaces just get too big. If there is not enough support for the land above the spaces, then a sudden collapse of the land surface can occur. These collapses can be small, or, as this picture shows, or they can be huge and can occur where a house or road is on top.
The most damage from sinkholes tends to occur in Florida.
