The project was to seal the areas where the beam tie-backs had been patched and poured. There were 400 plus locations on three levels approximately 4 feet square each. The third level of the garage is below sea level. Also on the lower two levels there were a number of cracks in the wall which had leakage conditions. KOSTER KD 2 Blitz System was used on any wet or leaking areas including all wall cracks. All 400 plus beam tie-backs then had the KOSTER KD 2 Blitz applied where leaking, and then were covered with the KOSTER NB 1 System. Urethane grout injection was included in the specification to handle leaks, cracks or any other areas where the KOSTER NB 1/KD Systems were not able to stop moisture. At the conclusion of the job, no Urethane grout was required at any location.
