Pedestal Installation Guide for Pavers and Rooftop Deck Systems

Adjustable pedestal systems provide a fast and efficient method for installing porcelain pavers, concrete pavers, and deck tiles on rooftops, terraces, balconies, and plaza decks. These systems create a stable, level surface while allowing proper drainage beneath the installation. This guide outlines the key steps for installing pedestal systems over waterproofing membranes and other structural deck surfaces.

Common Applications

Pedestal systems are commonly used for:​​

  • Rooftop decks
     

  • Plaza decks
     

  • Commercial terraces
     

  • Porcelain paver decks
     

  • Concrete paver decks
     

  • Landscaped podium decks

These applications benefit from adjustable pedestal systems that provide proper drainage, level surfaces, and long-term durability.

Installation Over Waterproofing Membranes (Rooftop Decks & Plaza Systems)

Pedestal systems are often installed over waterproofing membranes on rooftop decks and plaza structures. The wide base of each pedestal helps distribute weight evenly while protecting the membrane below. In many applications, protective pads or separation layers are recommended between the pedestal and the membrane to reduce the risk of damage. Always follow the waterproofing manufacturer’s guidelines when installing pedestal systems over protected surfaces.

Leveling Uneven Surfaces with Adjustable Pedestals

Adjustable pedestals are designed to correct uneven deck surfaces quickly and efficiently. Each pedestal can be individually adjusted to create a level walking surface, even when the structural deck has slope or irregularities. This makes pedestal systems ideal for rooftop decks and terraces where proper drainage and surface leveling are both required.

How Many Pedestals Do I Need Per Square Foot? (Spacing Guide)

The number of pedestals required depends on the size and type of pavers or deck tiles being installed. In most applications, pedestals are positioned at each corner of the paver. Larger format pavers or areas with higher load requirements may require additional pedestals at midpoints or center locations. Always follow the paver manufacturer’s spacing recommendations and consult a pedestal spacing guide for accurate layout and support.

As a general guideline, pedestal spacing is commonly based on 16" to 24" intervals depending on paver size and load conditions.

Products Used in Pedestal Deck Systems

Typical pedestal deck systems include adjustable pedestal supports, separation pads, and porcelain or concrete pavers. Pedestal heights can be adjusted to achieve the desired finished elevation while maintaining proper drainage beneath the deck surface. Additional accessories such as edge restraints or leveling shims may also be used depending on the application.
