This commercial development project involved reusing approx. 200m3 of fill onsite to backfill large pre-cast retaining walls, as well as raising carparking areas. An additional 600m3+ was exported in truck and quad dog trailers. Our subgrade preparation consisted of proof rolling, filling in 100mm lifts and compacting with a 13t padfoot roller to prepare for concrete. Lastly, the area was trimmed to grade ready for concreters and drainer.
