Re: [engineeringcivil] YOUR ADVICE REQUIRED [1 Attachment]
- Hi Mohaideen,Depth of excavation depends on the soil type, number of floors and other load data. Generally, depth of excavation should not be less than 1500 mm for very hard strata or more safely as 2100 mm. But again, this is a general condition and should be adopted as per site conditions.RCC depth of 300 mm should be cast in single pour over PCC of a minimum thickness 100 mm.
