Volume Concrete LLC., delivers Cellular Lightweight Concrete used for backfill – great for underground pipe and tank decommissioning.
Two types available permeable and non-permeable.
Wet cast weight: 25 lbs. cu./ft. – 60 lbs. cu./ft. with compressive strengths from 80 p.s.i. up to 1,000 p.s.i..
35 pounds per cubic foot (while wet) is the most popular mix design used for residential backfill that needs drainage. Any cast weights exceeding 35 pounds per cubic foot are non-permeable and widely used for underground decommissioning items like abandoned pipes, vacated sewer and old oil cisterns/tanks.
Why use Cellular lightweight concrete? The cellular concrete is applied via a hose, thus no heavy machinery is needed for placement. Lightweight cellular concrete is great for backfilling between the earth and concrete retaining walls, lessening the lateral loads applied.
No compaction or vibration is necessary. Self leveling and minimal formwork is needed for retainment while wet. Exceeds natural soil or compacted rock for load bearing capabilities.
