Deck pedestal system

Types of deck pedestal system

A deck pedestal system is a foundation support structure for raised decks. The system consists of adjustable pedestals, support beams, and deck tiles. The pedestal system provides a stable, level, and durable foundation for the decking. It is ideal for flat roofs, terraces, and other elevated surfaces.

The deck pedestal system comes in different types. Each type has unique features tailored to specific applications. Here are the most common types:

• Adjustable Pedestal System

  The adjustable pedestal system is a popular type among contractors and architects. It features a unique height adjustment mechanism. The mechanism allows the user to create a level surface over uneven ground. The system consists of a base, a stem, and a headpiece. Each component serves a specific purpose.

  The base is the foundation of the pedestal. It distributes the weight of the deck tiles to the ground. The stem is the vertical part of the pedestal. It supports the headpiece and the deck tiles. The height can be adjusted using screw threads or friction clips. The headpiece is the top part of the pedestal. It supports the joists and deck tiles. The headpieces come in different designs to support various joist configurations.

  This system is ideal for supporting terraces, balconies, and roof gardens.

• Fixed Height Pedestal

  This type of pedestal is not height adjustable. It comes in pre-determined heights. The fixed-height pedestal is less expensive than the adjustable type. It is used in applications where the ground is level. It is also used in situations where the height adjustment is not necessary.

  Support beams and tiles are easy to install using a fixed-height pedestal. The system is ideal for residential decks and patios.

• Heavy Duty Pedestal

  The heavy-duty pedestal is designed to support large and heavy loads. It is made from strong materials like polypropylene and recycled plastics. The materials can withstand harsh environments and weather conditions. This type of pedestal is popular in commercial applications. It is used for supporting large timber or composite decking. The heavy-duty pedestal can support a weight of up to 2,000 pounds. It can also be adjusted to different heights and slopes.

• Solar Roof Deck Support

  These support pedestals are specially designed for solar panel arrays. They support both solar panels and outdoor spaces like decks or patios. The pedestal system provides easy access to solar panels for maintenance. They also allow for proper drainage and airflow. The solar roof deck support system is ideal for sustainable building designs.

Functions and features of deck pedestal system

Below are the functions and features of the deck pedestal system:

• Height adjustability

  Adjustable pedestal for decking enables the construction of terraces and walkways at different elevations. They can raise up to 1.6m, allowing the creation of raised timber patios or cool floating decks. These height-adjustable pedestals can also be stacked to achieve a higher elevation.

• Slopes and drainage

  Some decking pedestals have inbuilt slope adapters that help create a gentle slope on the deck. They help drain water towards the edges and prevent pooling. The drainage gaps between the boards also facilitate airflow and avoid moisture buildup.

• Material support

  Decking pedestals support various decking materials, including timber, composite, and porcelain. They allow the use of different decking materials by offering adapters and support bars that secure the boards in place. The system can also accommodate timber of different widths and thicknesses.

• Robust structure

  These pedestals are usually made of high-quality materials like recycled polypropylene or aluminum. These materials are resistant to weather elements, corrosion, and UV rays. They provide long-term support and stability to the deck.

• Easy installation

  The pedestal system provides a simple deck construction process. Most of the systems are screw-based, enabling quick assembly without prior experience. They reduce installation time and increase the deck's stability and durability.

• Ventilation and access

  These systems create gaps between the decking boards for air circulation. The airflow helps regulate temperature and prevent moisture and mold growth. The gaps also provide easy access to the underside of the deck for maintenance and drainage.

• Load-bearing capacity

  The deck pedestal system can support substantial weight. For instance, a single pedestal can support up to 1,000 kgs. The system distributes the weight evenly across the support points, providing a stable and durable foundation for the deck.

Scenarios of deck pedestal system

The deck pedestal system is a versatile solution for supporting elevated decking in various applications. Here are some common usage scenarios:

• Balconies and Terraces

  Balconies and terraces, especially in urban settings, are ideal candidates for pedestal-supported decking. These areas benefit from the quick installation and adjustability of the pedestal system. The ability to create a level surface without heavy machinery or extensive labour is particularly valuable in space-constrained environments.

• Rooftop Decks

  Deck pedestals are often used in rooftop applications, such as creating outdoor spaces on top of commercial or residential buildings. The adjustable pedestals allow for proper drainage and ventilation while supporting a level and stable decking surface.

• Parking Garages

  Pedestal decking can transform underutilized spaces like parking garages into functional outdoor areas. For example, using a pedestal system can create green spaces, seating areas, or recreational spaces on top of parking structures while ensuring proper drainage and support.

• Pool Decks

  A pedestal system can create a raised decking area around a swimming pool. This application allows for water to be easily drained from the deck and underneath the deck boards. The adjustable heights can create a tiered seating area or shaded spot away from the water.

• Commercial Spaces

  Some commercial spaces, such as cafes or restaurants with outdoor seating, may utilize a pedestal deck system. This setup can quickly install a raised patio for tables and chairs, providing a pleasant dining environment.

• Environmental Remediation Projects

  In environmental remediation projects, a pedestal deck system may be employed to create temporary or permanent structures above contaminated soil or sensitive areas. The raised platform provides a safe space for activities while minimizing ground disturbances.

• Event Spaces

  Raised decking supported by pedestals can create tiered seating areas or elevated platforms for speakers and performers. The adaptability of the system allows for custom configurations to suit event requirements.

• Residential Applications

  Deck pedestals are commonly used in residential settings, such as patios, porches, and poolside lounges. These systems are easy to install, providing homeowners with cost-effective solutions for creating level and stable decking surfaces.

How to choose deck pedestal system
