ResinDek 10 year product warranty image

ResinDek® flooring panels, manufactured by Cornerstone Specialty Wood Products, LLC® provide a tremendous value for elevated floors in self-storage buildings. ResinDek composite engineered wood flooring panels are extremely durable, provide a showcase appearance and are easy to maintain. They have the proven structural integrity and the strength you associate with a concrete floor yet can offer savings of tens of thousands of dollars. ResinDek panels offer a compelling value for both new construction and retrofitting existing facilities and is backed by a 10-year product warranty.

How can you realize savings of up to $5/sqft by using ResinDek instead of concrete and get a product that is backed by a 10-year warranty?

  • ResinDek is at least 40 lbs per square foot lighter than concrete which allows for less steel to be used in the support structure, along with potential savings in the foundation and footers.
  • ResinDek is supplied with a factory finish so tracks can be laid for the storage units immediately after the flooring is installed. Concrete typically needs a week or more to cure before tapcons can be used to continue construction.
  • ResinDek has an allowable deflection of L/240 whereas concrete's allowable deflection is L/360. This creates a more ergonomic platform and again allows for less steel in the support structure.
  • Material cost per square foot is less than that of concrete.
