Situation:

The new flagship H&M clothing store located at Herald Center in Manhattan, New York is the largest H&M store in the world. When the building owner began renovations to prepare the historic building for the store opening, some serious flooring issues where discovered. The 90 year-old floors required leveling before new large format porcelain tiles could be installed by six union tile crews throughout the space.

Challenges:

• Three month installation time frame
• More than 52,000 square foot installation area
• Renovation of 100 year old building to accommodate large retail space
• Agglomerate tiles to be set with non-staining tile and stone mortar
• Installers first time using ARDEX tiling products

Solution:

ARDEX Sales Professionals Dan Costanza, Kevin Manning and John Lutkowski, National Accounts Manager Jen Davis and ARDEX Field Technical Representative Jeff Smith supported this high profile installation at various stages. Dan Costanza was contacted by the flooring distributor to suggest appropriate installation products that would qualify for a full ARDEX SystemOne warranty. The building owner had previously installed six truckloads of ARDEX GS-4™ Self-Leveling Repair Underlayment for Distressed Gypsum and Wood Subfloors and was ready to install tile. ARDEX 8+9™ Rapid Waterproofing and Crack Isolation Compound was installed as an anti-fracture remediation tactic. Forty-six thousand square feet of various sizes of large format porcelain tiles were installed with ARDEX X 77™ MICROTEC® Fiber Reinforced Mortar. To finish the job ARDEX FL™ Rapid Set, Flexible, Sanded Grout in Silver Shimmer, Cast Iron and Irish Crème was applied. A 6,000 square-foot feature wall showcasing 30”x 30” agglomerate tiles required a mortar that would not stain or warp. ARDEX N 23™ MICROTEC® Rapid Set Natural Stone and Tile Mortars’ proprietary self-drying formulation prevents warping, staining and discoloration of moisture sensitive stone making it ideal for this highly-visibly installation. A full 10 year SystemOne™ warranty was received for this impressive installation. Installers stated that ARDEX tiling products were exceptionally easy to use and the support from the ARDEX team made the job a success.
