  1. Replace unsuitable soils, materials that can not support road conditions
  2. Lightweight fill over utilities such as water, sewer, gas & electric lines
  3. Lightweight fill that will reduce or eliminate long term settlement
  4. Soil substitution that will reduce or eliminate side slope movement


  1. Reduces the lateral forces that standard earth fill puts upon vertical walls
  2. Absorbs the potential movement of backfill from frost heaving
  3. Disperses the overall weight of the structure in building construction
  4. Lightweight support under concrete pads for utilities (transformer pads, etc.)
