Intersecting fractures can become enlarged into chambers and caverns, and the soil-bedrock interface can become pinnacled. The soil cover is subject to movement into the bedrock voids, aided by downward percolating water, resulting in soil voids which migrate toward the surface. When the “roof” of a soil void nears the ground surface, a collapse of the roof can occur, resulting in a sinkhole.<br/><br/><strong>How to look for sinkholes<br/></strong><br/>Early signs of sinkholes include:<br/> - Newly developed areas of pavement that hold water after rain events<br/> - Settled sections of curbs or stormwater inlets<br/> - Failed sections or holes in pavement<br/><br/>These signs may develop rapidly and continue to detiorate over several days or weeks.<br/><strong><br/>If you think you may have a sinkhole developing on your property call us to have a look.<br/><br/><br/></strong>David Harmanoshttp://www.blogger.com/profile/13626592540193528538noreply@blogger.com
