Cellular Concrete Solutions has been offering low-density Cellular Concretes to the mining, tunneling and geotechnical construction industry for over 60 years. Its Mearl Geofoam liquid concentrate produces stable preformed foam able to withstand the vigorous requirements of underground and below/at grade applications. Preformed foam can incorporate a wide range of materials such as tails, sand, fly ash and crusher fines with cement to create an engineered fill that meets your specific density and compressive strength needs. Backfills, annulars, ground support, abandoned pipes and tanks, and replacement for poor soils are just a few situations where cellular concrete can be applied. Its most recent innovations include the development of foams that serve as transport agents for rock dust, mine tailings and other fill materials, cutter head foams for TBMs and new synthetic concentrates that produce pervious cellular concrete.
