The Foam Generator1. High strength with low densityTypical cast densities range from 25 to 55 pcf, with compressive strengths of 40 to 750 psi, respectively. With its low density, foam concrete imposes little vertical stress on the substructure, a particularly important issue in areas sensitive to settlement. Due to its low density, foam concrete is a viable solution for reducing loading on burdened soil. Additionally, foam concrete is less susceptible to differential settlement. Heavier density foam concrete with higher strengths is produced and used for specialty applications. lightweight backfill, bridge abutment backfill, abutment backfill 2. Rigid, well-bonded bodyFoam concrete forms a rigid, well-bonded body after gelling (hydrating); thus, it is effectively a freestanding structure on its own and does not impose lateral loads on adjacent structures. The material can be constructed into various formations and profiles by forming and stepping of successive lifts. Foam concrete can also be machined to create a desired effect. load reduction, lightweight fill, load reducing, load-reducing 3. No Compaction RequiredIn some cases mechanical compaction can be difficult and unsafe due to limited or inaccessible areas. In excavations with poor soils that are not easily or incapable of being compacted, foam concrete forms a 100% compacted foundation over the soft soils. When compaction of conventional backfill against retaining structures or deep foundations, traditional methods can cause damage or movement to the adjacent structure or just be too time consuming. In these instances, foam concrete is a great solution.lightweight retaining wall backfill, MSE wall backfill, lateral load reduction fill
