A typical installation would start off the threshold of a door or control point, provided by architect or contractor. The first height of the Pedestal System pedestal is then determined. (A standard chop saw with fine tooth blade (12″) compatible with plastic) can cut the PVC height insert.
An installer then cuts the PVC to the required height, less the 1/4″ inset for each top and each bottom cap, e.g., a 1-1/2″ pedestal needs 1″ PVC and the 1/2″ top piece which insets 1/4″, plus the 1/2″ bottom cap which insets 1/4″ — making the total pedestal 1-1/2″ high.
The “press fit” of the caps — top and bottom — requires no gluing or other attachments. The caps can be easily removed during installation if desired. Both the small top shims and round bottom shims can be used for “fine tuning” the proper height, if required. All top shims and bottom shims lock into place, and all six pieces (if used) interlock, allowing no paver movement and a level surface.
For proper heights lower than 1/2″ the Tile Tech Pedestal System standard cross, 1″ l ong, 1/2″ high and 1/8″ thick can be used with the Pedestal System standard 4″x4″ square shim, both in 1/16″ and 1/8″ thickness (though we recommend that if construction permits, it is always preferable to have at least a 1″ gap under pavers to allow for airflow and water movement).
The 4″ PVC used in the Pedestal System may be either of two standards: 2729 or 3034. Both are off-the-shelf products, standard in North America with the outside dimension of 4.215″, matching the inside diameter of the Pedestal System top and bottom cap.
Typical use is the thin wall PVC (2729). Independent compression tested from 1″ up to 5″, ranges from 7,000 to 15,750 psi. Thicker wall PVC (3034) 4.210″ OD, 5″ up to 27″ compression tested 11,000 to 13,200 psi. (NOTE: all testing done with both top and bottom Pedestal System installation caps in place.)
