Sinkhole Restoration

Sinkholes are formed when a soluble limestone and dolomite are dissolved by acidic rainwater. This creates solution channels, fissures, and interconnected void veins within the limestone formation. As water percolates through the overburden soils into the limestone formation, part of the soil is transported into the limestone formation.

Three general types of sinkholes are prevalent in Florida: dissolution, cover substance and cover collapse sinkholes. The type of sinkhole is controlled by the thickness and type of overburden materials. Sinkholes can be a combination of the three types, and may form in several phases.

Dissolution Sinkholes are formed by rainfall and  surface water percolating through joints in the limestone.

Cover Subsidense Sinkholes tend to develop gradually where the covering sediments are permeable, and are transported into the underlying carbonate rock, eventually forming a noticeable depression in the land surface.

Cover Collapse Sinkholes may develop abrubtly (over a period of hours), and cause catastrophic damages to houses, commercial buildings, and roadways.

If not detected and properly repaired by a sinkhole expert such as C&N, sinkhole activity can severely damage or even completely destroy structures that rest above or adjacent to them. Each year, sinkholes are responsible for devastating losses to homes and property owners.

To solve sinkhole related problems, C&N works closely with professional geotechnical and structural engineering firms utilizing one or more of the following stabilization methods: compaction grouting, shallow grouting, underpinning, chemical grouting, injection piers, and pre-construction piers.
