Voids, Hollows, Caverns, Dens….are you dealing with void space under your concrete?

One of the advantages of using Geo-polymer for filling voids is its light weight. Various formulations can be ordered but our polymer of choice is HMI’s RR401g. For large void fill jobs lighter duty polymers can be a very cost-effective alternative to gravel or other materials.

Weighing four pounds per cubic foot or just over one hundred pounds per yard you won’t overburden soils, especially compared to concrete at thirty-three hundred pounds per yard.

Recently we filled a void under a driveway. Due to a drainage problem water had been running under the drive gradually settling the base soils and washing away the fines opening up a void of roughly four inches.

We drilled a series of holes to ensure excellent coverage and injected from the center of the slab toward the edge to push material all the way to the edge. Using gauges that are capable of measuring movement of a 1/1000″ insures we are supporting but not lifting or stressing the slab.

When you need a void filled you can trust 1-855-752-2522 to do it properly and economically.
