Fixed Height Supports

Fixed height paver support pads

When constructing elevated decks with unit pavers over sloping surfaces including rooftop decks and terraces, at the very lowest elevations below approx. 1″ (the min. height of Eterno NM1 adjustable height pedestals), fixed height rubber support pads are normally the best solution. These stackable pedestal supports are simply placed under each corner of the pavers. The pads have spacer tabs built in to enable quick and easy installation and ensure all pavers are accurately spaced and aligned.

We recommended rubber pads rather than plastic pads for these low height applications (despite the slightly higher cost), since they offer:

  • superior sound absorption
  • added shock protection
  • greater friction between both the pavers and the substrate

 
Furthermore, because the increased friction of rubber inhibits pavers from moving, you can often avoid the trouble and expense of constructing a perimeter restraining barrier around the paved area.

You can start with support pads as low as 1/4″ high (giving a finished deck height of just 1″ with a 3/4″ thick porcelain paver) and then stack the support pads on top of each other to a maximum height of approx. 1 1/2″ as you continue your installation across a sloping surface.  1/16″ or 1/8″ thick rubber shims can be laid between the paver and the pedestal head to make minor height adjustments and ensure the pavers do not rock.

Once you reach a height of approx. 1 1/2″, you’ll need to switch to adjustable height pedestals if you require additional height for your deck, using either the Eterno SE range with its self leveling heads, or the  lower cost NM ‘Maxi” range with its fixed heads and leveling shims.

Pavers laid with fixed height support pads ‘floating’ directly over existing concrete surfaces offer considerable advantages over thinset laying:

  • faster and easier to install
  • build perfectly horizontal surfaces by stacking pads
  • no cracking/lifting of tiles due to water penetration
  • water drains rapidly – no pooling

 
Architrex currently offers two types of rubber support pads, both of which have similar features.

 

Eterno Rubber Support Pads
  • low min. profile – just 1/4″ high
  • 4 3/8″ diameter
  • stackable up to approx 1 1/2″ high
  • three components only
    1/4″ pads ETE-PAD6
    3/8″ pads ETE-PAD10
    1/16″ shims ETE-LGH2
HD Series Rubber Support Pads
  • low min. profile – 3/8″ high
  • 6″ diameter
  • stackable up to approx 1 1/2″ high
  • HD-PAD16 can be stacked on NM Maxi pedestal heads
