Hi Bryan, Many thanks for your prompt response.In regards to #4, your proposed Hilti's filler (CB-G-EG) is not available where the installation takes place here in Poland.Therefore, we plan to use a different product that is locally available. There are some products available which provide a min. compressive strength 40 MPa where C30/37 class concrete had been used at the entire building in question.Shortly, can you please advise us if we can use other products than the one you suggested to fill the space due to chipped concrete in some locations the HIS-N inserts protrude out approx. 20 mm.
