Void Filling & Foundation Repair

Proudly Servicing the Greater Alabama Area

Bulk-In-Fill Grouting is typically called for when the roof of a void collapses, a sink hole or depression forms and produces deformation of the ground surface. The gradual deterioration of the void, usually over a period of years, most often appears as a cone shaped depression.

Void Filling Alabama, Sinkhole Remediation Alabama

In addition to underground voids, sinkholes can also be repaired using void filling methods and are a fairly common problem that we encounter at Nichols / Grout Tech. Sinkholes are holes in the earth that are covered by a layer of soft rock such as limestone. These hole can sink in if the rock deteriorates or collapses. Sinkholes can range in size, being very small, or very large. Sinkholes and underground voids are serious threats that can cause damage to your foundation.

Signs of a Sinkhole in Alabama

There are many signs to look out for, when it comes to sink holes. Shallow sink holes are easily fixed with a rock filling, however larger sink holes require a process called sink hole remediation. In this process, grouting and underpinning are used.

Some signs that may indicate voids or sinkholes:

  • Water pooling in your yard
  • Depressions in your yard
  • Cracks in walls, foundations, slabs, floors, or bricks
  • Doors and windows that stick
  • Cabinets that stick
  • Sinking fence poles or vegetation
  • Sloping floors
  • Garage column cracks
  • Stairs or stoops that pull away from the foundation
  • Sediment in your water
  • Exposed sections of foundation that you couldn’t see before

Void Filling Alabama

Filling in pipes with cement

Filling of the void is conducted in one of several ways depending upon a variety of factors including: location of the water table, the size of the cavity, its proximity to the surface, and its location in relation to structures.

One common and simple technique used to stabilize the subsurface and prevent subsidence is using cement based Portland cement or chemical grouts and foams to fill the cavity below.

This method employs the use of pneumatic or drilling equipment to install pipes that connect the surface to the void. The pipes act as conduits to the subsurface voids, allowing the grout to be installed.
