The purpose of this project was to repair the parking garage and to provide front entrance waterproofing at the Hilton Crystal City Hotel. The garage contains 3 levels of parking. The P1 level is slab on grade construction with spread footings supporting each column. The elevated levels, P2 and P3, are conventionally reinforced 8” thick concrete slabs.
