This project consisted of filling a pie shaped backfill with approximately 20,000 cubic yards of cellular concrete. The structure was built with 35 feet of the structure below grade in order to reduce the height of the stadium to accommodate adjacent airport traffic. The exterior sub grade walls are protected with a 27 pcf cellular backfill approximately 4 feet wide at the base and nearly 30 feet wide at the grade level. The results leave no lateral load on the walls and give a minimal protection from seismic activity due to the cellular concretes’ ability to absorb shock in its structure. This fast track project was made possible by the ability of our crew and equipment to pour out volumes of up to 2200 cubic yards of cellular concrete in a single day.

When assessing the land for this hotel location, it was discovered that it was composed entirely of bay mud. In order to create a solid base that would support the structure rather than cause it to sink, 4 to 5 feet of soil was removed and 27 pcf cellular concrete was installed. This formed a base for the beam wall foundation of this 3-story hotel. This load reduction of approximately 480 pounds per square foot of removed soil is balanced by the addition of 80-100 pounds per square foot of cellular concrete plus 280 pounds per square foot of building. The entire hotel now rests upon the cellular concrete fill and is essentially buoyant upon the soil.

Located in the vicinity of 23rd Ave. and the 17 Freeway in Phoenix, Arizona, this project consisted of an abandonment of sewer pipe approximately 2½ miles long. The abandoned sewer consisted of RCP up to 60 inches in diameter. The pipe was filled from manhole to manhole with cellular concrete with the longest part of the fill requiring approximately 350 cubic yards of fill. (Note: this cellular concrete proves to be the best material to fill this size of pipe). Unlike CLSM, Slurries, and sand, cellular concrete has superior flow characteristics with low density and little to no detectible shrinkage.
Client: City of Morro Bay
Location: Chorro Creek Bridge, South Bay Blvd. in Morro Bay, CA
Date: October 1996
This project consisted of filling the base at each end of the bridge in an effort to reduce the load on the existing soil, eliminating any settling of the approaches. The fill consisted of 3,432 cubic yards of 27 pcf cellular concrete, which has a dry density of approximately 21 pcf, and reduced the weight of both approaches by nearly 9 million pounds. This project was completed in October of 1996.

Location: Parkside: La Palma & Jennifer, Anaheim, California
Date: March 2001
This project consisted of an existing field with a 51” R.C.P. sewer pipe that was under approximately 12 feet of soil. The plan for the field area was to build new homes, thus requiring the soil level be raised to the elevation of the surrounding streets. Although this 51” R.C.P. pipe only ran under the new street, the additional weight of 14’ of soil plus the anticipated traffic load far exceeded the design of the 51” R.C.P. The method to resolve this overload was to remove approximately 12’ of soil from above the pipe and then fill the area with Elastizell Engineered Fill in order to raise the grounds’ elevation. The removal of the soil reduced the load on the pipe by approximately 1440 psf. The addition of 25’ of Elastizell Engineered Fill resulted in 20.5 pcf or a total of 512 psf, which equaled about ½ the original weight with nearly twice the height.
