Tectonic® Decking Subframes

A decking subframe is the structure that sits beneath your deck, keeping it supported and providing the base that your decking boards are attached to. The key to a long lasting deck is a well constructed subframe comprised of high quality materials, set correctly in an appropriate foundation. Tectonic® is Ovaeda®’s premium subframe option, and can be used with the Tectonic® pedestals as part of our new landscaping subframe system. This all-weather, durable and non-combustible material is a non-rotting alternative to timber and is perfectly suited to spaces exposed to damp, such as jetties, pools, roof terraces and boardwalks.

Tectonic® Pedestals

The Tectonic® joist pedestal system was designed to make installation significantly easier and to ensure successful outcomes. The ultimate support system for your frame, providing substantial height flexibility within four stackable components, Tectonic® removes the common problem of having to order varying height pedestals for a single area. Height-adjustable from 10mm Tectonic® cradles, Tectonic® makes accurate height-setting easy, with self-levelling pedestals from 40mm upwards.
