Hello everyone
The column height in the structure is 11 ft. The columns had been cast already but then demolished to a height of about 3 ft i.e columns that are currently standing are of 3 to 4 ft. The columns ar 12 in x 18 in. I need to pour freah concrete over these pre existing columns to raise them to 11 ft height. These columns are in the basement rising from the raft. Will using sbr and providing holes for the fresh concrete to create a lock be enough? Any research papers related to this will be very helpful. Thank you.
