LaGuardia Airport, New York

SITUATION:

HOK/Skanska-Walsh was looking for a single source manufacturer to provide solutions that address concrete flatness, levelness and moisture mitigation and the porcelain tile installation. ARDEX Americas prepared a recommendation that covered all facets of installation including ACMS, anti-fracture membrane as well as high performance tile mortar and grout, in compliance with our comprehensive ARDEX SystemOne Warranty.

CHALLENGES:

  • Large amounts of material, and more than usual depth
  • Union labor market requiring OSHA certification training for Pump mechanics, sales professionals, truck drivers
  • Dense, urban job site settings and an ambitious, ever-changing schedule

SOLUTION:

The first phase of the project made use of ARDEX Concrete Management Systems, a patented, specified finishing method for new concrete construction that includes an integrated system of moisture control and self-leveling underlayment products. To address the moisture issues the One-Coat Moisture Control System ARDEX MC RAPID was installed.

In addition, the high-capacity pump POWERFLO was used to cut down on the time and labor. It had to work around cold weather and space constraints causing the project to last 18 months with dozens of mobilizations. Over 900 tons of ARDEX V 1200 were pumped covering 150,000 sq. ft. at an average depth of 1 ¼”.

For the tiling side of the project, ARDEX 8+9 antifracture membrane was installed in accordance with ANSI 118.12 providing a semi-elastic membrane designed to reduce cracking in the tile installation system. Next, the Tile & Stone Mortar ARDEX X 77 was selected for its superior non-slump properties while providing the contractors the extended working time to help facilitate proper transfer of mortar to the backs of the 24” x 48” LFT porcelain tile.

This redevelopment is the largest public-private-partnership (P3) in U.S. aviation history and one of the most complex projects ever undertaken by Skanska. By combining products and systems with high-performance properties ARDEX satisfied the demanding requirements of this project.
