Can You Build a TimberTech Deck Over an Old Concrete Patio?

September 30, 2016

TimberTech deck planks cannot be installed directly over an existing surface. However, with the use of a minimum of a 1-1/2” sleeper system supported by and connected to the substructure (concrete), TimberTech planks may be utilized in this application.

Best Practices for Installation

  • Be sure to have provisions for drainage in place, because the supporting sleeper system cannot impede drainage.
  • The sleeper system should be set to a maximum span for the specific decking profile of choice.
  • As with any project, we recommend you review local building codes and if needed, consult a contractor prior to installation.
