Adjustable pedestal systems are widely used to support concrete and porcelain pavers on rooftop decks, terraces, and other elevated surfaces. These systems allow precise height adjustment while protecting waterproofing membranes and enabling proper drainage. Because pedestals create a stable, load-bearing platform without mechanical fastening, they are commonly specified in both commercial and residential construction.

How Pedestal Systems Work

Load Transfer and Structural Support

Adjustable pedestal systems function as a non-penetrating support method designed to elevate pavers above the waterproofing assembly. Each pedestal acts as an independent load-bearing point that transfers weight directly to the structural deck while maintaining protection of the membrane.

​

The system allows installers to create perfectly level walking surfaces even when the substrate contains slope for drainage. Height adjustments are made at the pedestal rather than altering the roof structure, enabling precise alignment without mechanical fastening or adhesives.

​

Because pavers remain separated from the waterproofing layer, water flows freely beneath the finished surface. This drainage space reduces moisture retention, protects the roofing system, and simplifies future maintenance or repairs.

Advantages of Pedestal Systems

Pedestal systems provide benefits beyond simple elevation. Because the system is non-penetrating, the waterproofing membrane remains fully intact, eliminating the risks associated with mechanical fastening.

​

Adjustable pedestals also provide unmatched installation flexibility. Surfaces can be leveled with precision, slopes can be accommodated without structural modification, and individual pavers can be removed or replaced without disturbing adjacent areas.

​

From a long-term maintenance perspective, pedestal assemblies simplify inspection and repair of the roofing system. Components are reusable, layouts are adaptable, and drainage performance remains consistent over time.

Common Applications

Pedestal systems are commonly specified in both commercial and residential construction where elevated surfaces are required. Typical applications include rooftop decks, terraces, balconies, plazas, and podium assemblies.

​

Because pedestals create a stable, self-supporting platform, they are ideal for installations over waterproofing membranes, insulated roof assemblies, and protected roof systems. The ability to accommodate slope and drainage requirements makes the system particularly effective in complex building designs.

Pedestal assemblies are widely used with concrete pavers, porcelain pavers, stone slabs, and wood deck tiles, providing architects and contractors with a versatile and durable support solution.

Understanding Pedestal Systems

Pedestal systems have become a widely accepted solution for modern rooftop and elevated surface design. Their ability to provide structural support, drainage space, and long-term serviceability makes them a practical choice across a wide range of commercial and residential applications.
