  1. Well designed hole drilling patterns will minimize consumption of Dexpan® Silent Cracking Agent by cutting into desired sizes
  2. 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
  3. The coverage area of the Dexpan® silent cracking agent can be extended by filling every other drilled hole, as long as the material is not reinforced. 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 recommended for your particular job.
