Light weight fill.
Light backfill material for retaining wall.
The use of commercial by products such as furnace slag or fly ash as backfill material may be advantageous where such products are locally available and where suitable natural materials cannot be found.
The stability of the wall system is derived from the interaction between the backfill and soil reinforcements involving friction and tension.
