King West penthouse herringbone

What the job actually involved

Concrete plus hydronic radiant is a specification, not a suggestion. We used a 5/8" engineered European oak, the adhesive the mill warrants over heat, and a herringbone field that is actually square to the lake view, not to the longest wall. Floating would have voided the warranty. We did not float it.

Specification

• 2,400 sq ft

• Herringbone over hydronic radiant on slab

  Engineered European oak in a herringbone field, glued over a concrete slab with hydronic radiant beneath, to a specification the mill will still warrant.

  3 ways it goes wrong

What goes wrong on a job like this

• Floating a herringbone floor over radiant

  Voids the mill warranty outright, and a floating herringbone field telegraphs every slab imperfection as hollow spots underfoot.

  Avoided by: Full-spread glue-down in the warranted adhesive. There is no shortcut here.

• Adhesive chosen without an in-situ slab moisture reading

  Bond failure months later, under a finished floor, with the furniture in. The remedy is a full tear-out.

  Avoided by: Testing the slab and buying the adhesive to the reading.
