Projects of interest include the following: Produced and placed over 40,000 cubic yards of Geofill Low Density Cellular Concrete adjacent to MSE walls on the Expo LTR Phase 2 in California. Daily production rates of over 1,000 cubic yards were achieved. Production and long distance pumping of Geofill LD foam concrete to backfill the Brightwater East Tunnel in Washington. Over 70,000 cubic yards of low density materials were placed with pumping distances exceeding 2.5 miles. Produced and placed over 5,000 cubic yards of Geofill LD over existing floors as a leveling course at Modera Lofts in New Jersey. Other projects of interest include under water placements of Geofill LD Marine grout. Geofill LD Marine cellular (foam) concrete is specifically formulated for use in underwater placement applications. Geofill LD Marine is a lightweight, impervious material which remains in a cohesive, well blended mix when placed or pumped into a submerged environment. We have completed several projects in the NY/NJ area to encapsulate and protect timber piles that were under attack by Shipworms, Marine Borers and other organisms. This method of repair/protection is a preferred choice to either replacement or wrapping of individual piles. Due to the weakness of the river bottom soils, it is important to keep the protective backfill material close to the weight of water.
