Tysons Tower and VITA Garages Repairs included installation of a urethane traffic membrane to over 568,000 square-feet of garage slab. Full system coating thickness averages 56 dry mills exclusive of aggregate. Severe spider cracking around the columns were allowing water infiltration into the slab. 90,000 linear feet or cracks were routed & sealed prior to the waterproofing membrane application. Sealed cracks were detailed with liquid flashing a minimum of 2” on each side of the crack.  A #3 flint aggregate was used for a heavy duty and durable application in a busy commercial and residential parking garage. All levels were line-striped before reopening to traffic.
