This self-contained high volume dry mix unit produces the slurry (cement, fly ash and water) on-site. The slurry is combined with preformed foam during the pumping process.
This unit is capable of approximately 120 cubic yards per hour. The silos store the cement and fly ash (if used). Cement is augered from the silos into the weight batch hopper, then transferred to a mixing chamber where water and foam are added. After material is completely mixed, it is transferred to the pump hopper and pumped through a 3” grout hose while the next batch is being produced. This allows for continuous production.
This unit has successfully completed many high profile projects including stadiums and highways.
The proportions of cement, fly ash, water and foam are calibrated to achieve required densities. The ratio of slurry to foam determines the PCF of the product.

Load Reducing Backfill
This project required backfilling narrow areas up to 45’ deep between the new foundation and the sheet piles. Granular backfill would have required compaction which was logistically impossible, while flowable fill or CDF would exert too much load on the foundation wall.
Geofill Hybrid (70 PCF) reduced the lateral load against the foundation and eliminated hydrostatic pressure by being impermeable. The flowability of the material resulted in minimal disruption to the site.
