Utility Trench and Excavation Backfill

At The Conco Companies, we’re always looking for ways to reduce installation time, equipment, and labor needs. That’s why we offer ConFoam™, a low-density fill material created by mixing a foaming agent into a cement-based slurry, as a utility trench and excavation backfill alternative to traditional concrete. ConFoam is an alternative for traditional concrete, and is produced on-site in the exact amount necessary. Also called “liquid backfill,” its high flowability allows it to reach the deepest voids and eliminate the need for compaction testing.

ConFoam™ Takes Workers & Equipment Out Of Excavations

ConFoam™ is a low-viscosity material that is easier to pump than sand slurry, and guarantees better compaction and less settlement than traditional concrete. It achieves 100% consolidation, even in areas difficult to reach with traditional equipment. Workers don’t need to dig large excavation sites just to accommodate compacting equipment. Workers also don’t need to be in the excavation site during installation, and materials don’t need to be imported and stockpiled.

An Economical Alternative

Wasteless production and easy installation makes ConFoam™ a better choice for lower cost and a smaller carbon footprint. Furthermore, ConFoam™ is a rigid material that doesn’t settle over time, avoiding the need for rework. If removal is necessary, ConFoam™ can easily be excavated by hand tools including shovels and chainsaws.

Other benefits of using ConFoam™ as a utility trench and excavation backfill include:

  • Reducing the dead load over existing pipe structures or poor soils
  • Providing excellent load-bearing characteristics under roadways and public spaces
  • Eliminating the need to shore deep excavations before filling them
  • Avoiding the challenge of meeting compaction requirements

Conco’s goal is to be the top supplier of concrete services in the Western U.S. and to bring our expertise and professionalism to each project. We continue to improve our facilities to better serve the growing market for commercial, industrial, and public projects. Contact The Conco Companies for information on how you can save time and money with ConFoam™ utility trench and excavation backfill.
