12.3 - Cleaning the decking

Back to main Contents page

Prior to the concrete being placed, the decking should be cleared by others of any debris, grease and/or dirt which could adversely affect the bond between the concrete and the decking. Typically, ceramic ferrules from the shear stud thru-deck welding process can be left distributed over the decking surface and lost within the concrete pour. Final clarification should be sought from the project structural engineer
