During the process of construction, large quantities of soil will be removed as part of building the foundation. An easy way to reuse this soil is it use it for backfilling.
Backfilling or Foundation Filling
Back filling is the process of reusing this soil to strengthen the foundation. A mixture of several materials like rock, soil and stone are commonly used for back filling. The excavated materials should be cleaned and cleared of all grass, loose stones and rubbish before filling.
Filling is usually done in layers. Each layer is watered and compacted with heavy logs of wood or steel.
