Question- A square pile group of 9 piles having depth of 9 m passes through a recently filled up material of 4.5 m depth. The diameter of the pile is 30 cm and pile spacing is 60 cm centre to centre. If the unconfined compressive strength of the cohesive material is 60 kN/m² and unit weight is 15 kN/m³, the negative skin friction of the pile group is kN. www

Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.
