Cellular Concrete and Grout
Cellular Concrete is made with pre-formed foam added to either a sand, cement, and water, or neat cement and water, to achieve densities between 30 pcf and 110 pcf, and strengths between 75 and 1,200 psi. It can be pervious or closed cell.
Due to the flowable, insulating properties, cellular concrete is excellent for backfilling sheet piles, MSE walls, bridge abutments, and soft areas where dynamic and lateral loading is important. It is the best material for slipline grouting, abandonments, void filling and slabjacking. The low-density also works well in cold regions when lifting slabs or filling voids to help insulate the ground.
We have 3 foam generators to produce stable pre-formed foam for all cellular applications and do our own field testing for density on every load for accuracy and to determine volume.

Fairbanks - Cellular concrete was used as backfill in winter for the excavation of buried munitions under newly constructed homes on base.
Fairbanks - Low-density self-leveling 40 lb grout was used to flow under building with 100% compaction, setting up overnight, at over 200 psi.
