To insure success, Dexpan® needs Free Space to expand to. Make sure that the rock or concrete has an open face for expansion equal to the drilling depth. If there is no expansive space, extra holes may have to be drilled and protrude the rock / concrete

Doing this may decrease the set up time but is more cost effective by using less material. Please contact our technical staff to find out if this would be recommendyou’re your particular job
