Mine & Void Fill

Void Fill Grouting is typically called for when the roof of a void collapses, or a sink hole or depression forms producing deformation of the ground surface or when pre-construction site testing uncovers such potential defects. The gradual deterioration of the void, usually over a period of years, most often appears as cone shaped depression, or hole at the surface which can result in damage to buildings, utilities and roads.

Damage to structures from void formation may be minimal to severe. These damages may include cracking in foundation walls and floor slabs, cracking of brick veneer, vertical displacement of the structure with severe tilting an inability to properly open and close.

Using our onsite high volume batch and pump equipment, our operators are able to produce and place up to 1,000 cubic yards per day. Using the same quality control as our standard production method, we are able to consistently deliver cellular concrete at the density and strength specified.

Voids can form under a variety of conditions both natural and man made. Trash and rubbish buried during construction will produce a void as it decomposes. If the trash pit is located under a concrete slab, building footer or foundation structural damage will often result form the subsidence. Sanitary and storm sewer pipes breaking will allow fill materials to be carried away producing underground voids.
