Cellular Concrete Engineered Fill From Cell-Crete
Cell-Crete’s Engineered Fill (cellular concrete) has continued to grow in acceptance with proven results by both public agencies and the commercial and private sectors.  The increased acceptance is due to tireless product research and development by Cell-Crete and their team. The many varied successful applications installed by the Cell-Crete
Corporation provide confidence with our clients.  We are seeing increasing confidence from Geotechnical engineers, agencies, consultants, contractors, owners and designers in this game-changing product.
Cellular concrete is formulated specifically by Cell-Crete for
Geotechnical applications.  It is often used in difficult situations where either the standard fill materials are too heavy or alternate solutions are too costly and time consuming as demonstrated through project specific value engineering.
The various applications of cellular concrete are as broad as the
designer’s imagination.  Below are the most common applications of this
material, which may weigh as low as 20 pounds per cubic foot (pcf), more commonly around 30 pcf, and is considerably stronger (10X) than most soil and fill materials.
  1. Reduces dead loads on a structuredue to it high strength and low density while maintaining or increasing accompanying elevations.  This is especially important with older structures when new uses are contemplated.  This may save the difficult and costly strengthening of existing buildings, bridges, or specialized structures such as culverts, retaining walls and plaza fills.
  2. Place it over poor soils at a bridge approach or grade separation. The most common application, where the Cellular Concrete thickness at the abutment may vary from less than 5 feet to often more than 20 feet.  Different densities may be required in various locations of the approach fill to satisfy specific requirements such as strong enough to pave upon near the surface.
3. Eliminates Surcharging. With a properly load balanced application of Cellular Concrete there is no longer the cost or delay of            surcharging/wicking to stabilize deep soft soils.

4. Roadway base fill for rehabilitating an existing roadway or for the construction of a new road over a poor subgrade.  When maintaining an existing road, the additional weight of roadway leveling patches will often further consolidate the soil leading to additional differential subsidence.  For these, as well as new roadway sites over poor soils, cellular concrete provides a solid, yet lightweight roadway base, which reduces further settlements and will span most differential subgrade movement.  Water in an Elastizell subgrade does not cause weakness or settlement!

5. Ideal for void fill applications because of its lightweight flowability, ease of placement, cementitious properties and no need for compaction! These applications may include abandonment fills, annular fills for sliplined pipes, fills between both a pipe and a tunnel cut as well as a pipe and a cribbed excavation.  Other void fill applications may be sink holes, swimming pools, voids under slabs, and voids created by washouts.

6. Slab and footing pad fillsof ELASTIZEL EF will spread loads over larger areas as well as reduce the weight of these supporting structures.  These are important considerations over poor soils and can often replace more costly alternatives such as pilings, caissons, micropiles, surcharging, etc.

7. Eliminates lateral loading on retaining walls. Once cellular concrete sets, it does not apply lateral pressure.  Depending on its shape and location, the cellular concrete may be designed to reduce or eliminate soil pressures.  This may result in substantial savings in the design and construction of new structures or the remodeling of existing structures.

8. Pervious or Non-Pervious that is the question! Cellular concrete comes in two varieties non-pervious with permeability in the range of 1×10-6 and pervious cellular with flow down to 1×10-1.  The pervious version is often used for structural location where it is desired for water to escape or for buoyancy concerns.  Since the pervious version doesn’t displace the water it doesn’t float?
Examples of these uses include (many more available in the designers imagination):
  • Lightweight fills – Load Balancing (i.e., bridge approaches, building pads, and load reducing fills over below grade structures).
  • Fills Behind Retaining Walls
  • Foundation Fills both inside and outside the foundation
  • Landscaping and Plaza Fills
  • Roadway Fills
  • Landslip Repair Fills
  • Annulous and Pipeline Abandonment
  • Culvert Fills
  • Soldier pile removable CDF
