Sinkhole Foundation Repair Options

Grouting and/or Underpinning are the techniques used by APT in the Sinkhole repair process. Grouting is a method of Sinkhole repair or remediation in which Grout, a form of concrete, is pumped under or into the ground. The purpose of the Grout injection program is to grout within and along the top surface of the Limestone around the Property to restrict and/or seal breaches in the surface of the Limestone that connect the soils that overlie the rock surface to suspected cavernous bedrock zones, thereby reducing the potential for future subsoil raveling and migration. Underpinning is a method of subsurface repair in which metal piers, called Underpins, are driven into the ground and imbedded in the earth. Underpinning can repair structures (like your home) that have been damaged or have settled from Sinkhole activity, buried organics, shrinking/swelling clay, etc. Underpinning supports the foundation of a structure by transferring the weight of the structure from the foundation, through the unstable soils, to a more stable material below. One of our foundation repair contractors can determine what sinkhole remediation tactic or combination or tactics is best for your specific needs.

Compaction Grouting Process

The purpose of the Grout injection program is to grout within and along the top surface of the Limestone around the Property to restrict and/or seal breaches in the surface of the Limestone that connect the soils that overlie the rock surface to suspected cavernous bedrock zones, thereby reducing the potential for future subsoil raveling and migration. This strategy is intended for sinkholes that are caused due to an issue within the bedrock layers, as opposed to the chemical grouting process, which focuses on stabilizing loose soil near the surface.

Chemical Grouting Process

chemical grouting process for foundation repair due to sinkhole damageThe chemical grout process is designed for stabilization and densification of loose base and sub-base soils within the first ten feet beneath the property. The work will consist of furnishing all labor, equipment and materials required to inject polyurethane material to depths no greater than 10′ below the base of the slab on grade. The procedure is intended to stabilize the near surface soils by densification and/or infilling.

Underpinning

Uunderpinning foundation repair for sinkhole remediationnderpinning is a method of subsurface repair in which metal piers, called Underpins, are driven into the ground and imbedded in the earth. Underpinning can repair structures (like your home) that have been damaged or have settled from Sinkhole activity, buried organics, shrinking/swelling clay, etc. Underpinning supports the foundation of a structure by transferring the weight of the structure from the foundation, through the unstable soils, to a more stable material below. Once the Underpins are secured, they are then attached to the structure with brackets. Underpins are usually installed around the perimeter of the structure at set intervals determined by a certified Engineer. If needed, Underpins can also be placed under the interior of the structure, such as under the interior load bearing walls.
