Our Terra-Stand paver pedestal roof system lets you make the most of rooftop surface space.  

Terra System One provides a level surface for installation of concrete pavers over a pitched surface or roof. The system ensures precise paver alignment and even spacing that allows for drainage and air circulation critical to the health of a deck installed over any waterproof membrane. It also allows for easier access to the subsurface for scheduled maintenance or repairs without damage to the paved surface. Terra-Stand can also be installed at grade level where the surface is not pitched.  

The Terra-Stand is made of a high impact copolymer polypropelene adjusting from 3” to 21” in height and slope compensating up to 5/8” to provide a level installation. Outside base dimension of 7” x 7” provides contact surface of 49” square. It is installed on previously established grid lines, adjusted for height and slope and ready for installation. Load of 3,000 lbs per pedestal.  An average project will require one Terra-Stand for each paver, plus the perimeter.
Terra-Tab SBR rubber is recyclable and manufactured exclusively for the support of the paver on the Terra-Stand.  It has a shore hardness 70 (ASTM D 2240-91) allowing for resiliency without sound transmission.  Terra-Tab spacing tabs allow for perfect 3/16" (4.76 mm) joints.  Optional 1/8" (3.18 mm) tab area available for the #5A and #6A tabs. Average installation calls for one Terra-Tab per paver on a standard square or rectangular deck.  Decks of other designs will require more Terra-Tabs.  

#7 - 1/2" (12.7 mm) thick, 7" (17.78 cm) sq., 3/16" (4.76 mm) wide                   

#6 - 7/16" (11.11 mm) thick, 6" (15.24 cm) sq., 3/16" (4.76 mm) wide             

#6A - 7/16" (11.11 mm) thick, 6" (15.24 cm) sq., 1/8" (3.18 mm) wide

#5 - 3/8" (9.53 mm) thick, 5" (12.7 cm) sq., 3/16" (4.76 mm) wide

#5A - 3/8" (9.53 mm), 5" (12.7 cm) sq., 1/8" (3.18 mm) wide

Terra-Shims SBR rubber is recyclable, 1/8" (3.18 mm) thick, manufactured to coincide with Terra-Tab sizes. Optional 1/4" - #5 shims are available upon request.  Spacers allow for 1/8" or 3/16" spacing used in conjunction with Terra-Shim plates.  Terra-Tabs and Terra-Shims can be set directly on the waterproof membrane, on an optional protection board or insulation without harm.

#5 - 1/16" (1.59 mm) thick, 5" (12.70 cm) sq.

#5 - 1/8" (3.18 mm) thick, 5" (12.70 cm) sq.

#5 - 1/4" (6.36 mm) thick, 5" (12.70 cm) sq.

#6 - 1/8" (3.18 mm) thick, 6" (15.24 cm) sq.

#7 - 1/8" (3.18 mm) thick, 7" (17.78 cm) sq.

Waffle Reducer: High impact copolymer polypropolene made to accommodate height adjustments 1/2" to 3".  An outside base diamenter of 6" provides surface contact of 28" sq. in. The unit consists of one base with 3 pieces of 3/8" and 2 pieces of 3/4" waffle rings.

Blok Handle: Made of 10-gauge HRCQ steel allows for easy manipulation during installation without harm to the paver or other components, while allowing for 3/16" (4.76 mm) joints. The handle can make removal easy, should repairs to subsurface components be necessary.  Available in nominal 12" (30.48 cm), 18" (45.72 cm), 24" (60.96 cm)

Big Blok Handle: Is adjustable to work with nominal 24" (60.96 cm), 30" (76.2 cm) and 36" (91.44 cm) pavers.  Requires two people to operate.

Wheel Attachment: Takes the place of one handle, enabling one person to transport and place paver units.  Made of steel with a 16" x 6.5" pneumatic tire.

Back Saver: Holds pavers up to 36", enabling one person to transport and place paver units.  Made of steel.


Installation Specifications: 

Installation requirements depend upon individual project needs. Tectura Designs, Inc. will recommend tools and techniques; however, contractors should have experience in the installation of similar systems. Grid layout and pattern are determined by the architect or installing contractor. Typical installations begin by determining a starting point based on pattern layout. Next, measurements are taken and chalk lines placed. Terra-Stands or Waffle Reducers are then placed at the intersections of the chalk line and adjusted as required. A Terra-Tab is placed on top of adjusted unit. Terra-Pavers are then set on Terra-Tabs. Should repair to the sub-structure be needed, Terra-Pavers are easily removed and replaced with the Blok Handle or Big-Blok Handle.

Terra-Stand and other components are delivered factory direct with Terra-Pavers. Prices quoted upon request.

Full Terra System One installation, using all components, carries a Three-Year Limited Warranty. Individual components are warranted as follows:

Terra-Pavers - Three-Year Limited Warranty
Blok Handles/Big-Blok Handles - One-Year Limited Warranty
Terra-Tab/Terr-Adjust/Extender/Reducer/Terra System One Mix - Three-Year Limited Warranty

A copy of the complete warranty is available upon request.
Warranties can be negotiated for extension.

Complete Terra System installations require periodic cleaning by use of high-pressure water system to rinse off debris. Regular maintenance also includes adjustment of pavers that may have shifted or been damaged. Installations over waterproof membranes allow for access to the substrate for maintenance. Drains should be cleaned as needed to prevent water back up.
