Service at a Glance

Low density cellular concrete (LDCC) is a lightweight material made by replacing some or all of the stone aggregate used in standard concrete with uniform air cells (voids). These air cells are created by blending foaming agents into the concrete during the mixing process, and can be managed to produce an engineered geotechnical material. Its density can be varied from 20 to 120 lbs. per cubic foot, and its compressive strength from 20 to 3000 psi. Geotechnical applications include load-reducing fill, backfill for tunnels and retaining walls, annular grouting for tunnels, fill for bridge approaches, and fill for sinkholes and abandoned underground tanks, pipelines and mines. LDCC can be produced in both pervious and non-pervious blend.

Advantages of Low-Density Cellular Concrete

  • Low-density – By controlling the foaming action, it’s possible to create densities ranging from 15 to 120 lbs. per cubic foot
  • Excellent pumping qualities – thanks to its high air content and low density, cellular concrete is easy to pump – even over long distances
  • Light and durable – Cellular concrete is typically stronger than compacted fills or soils, even at its lower densities.
  • Permeable or non-permeable – Can be formulated to stop water penetration or allows it to drain through the material.
  • Self-leveling – Excellent flow characteristics. It performs well at filling voids and flowing to form a level surface.
  • Insulating – Captured air bubbles give the material much better insulating qualities than other masonry materials.
  •  – Allows for even heavy traffic just 15 minutes after completion of the injection of the material
