MATRIX PEDESTALS
Rooftop Deck Pedestal Systems for Pavers & Joist Applications
Adjustable pedestal systems are widely used in rooftop deck installations to support porcelain pavers, concrete pavers, and deck joist systems. Matrix pedestal systems create level surfaces over waterproofing membranes while allowing proper drainage and airflow.
How Pedestal Systems Work
Adjustable pedestal systems create a level, elevated surface for porcelain pavers, concrete pavers, and deck joists without the need for mortar or adhesives. Each pedestal consists of a stable base, an adjustable threaded body, and a support head that securely supports the deck surface.
The pedestal base rests directly on the roof membrane, concrete slab, or structural surface. The adjustable body allows installers to raise or lower the finished deck height, making it easy to compensate for uneven surfaces or roof slopes while maintaining a perfectly level walking area.
Pedestal systems also create an open cavity beneath the deck surface. This space allows for proper drainage, ventilation, and easy access to waterproofing membranes, electrical lines, plumbing, and other utilities when maintenance is required.
Matrix adjustable pedestals are designed for both residential and commercial applications and can be used with porcelain pavers, concrete pavers, natural stone, and deck joist systems.
Components of a Pedestal System
• Stable support base
• Adjustable threaded body
• Pedestal head with spacer tabs
• Optional slope correction accessories
• Paver or deck joist support surface
Advantages of Adjustable Pedestal Systems
• Creates a level deck surface on uneven substrates
• Allows proper water drainage beneath the deck
• Protects roofing and waterproofing membranes
• Provides access to utilities below the deck surface
• Fast installation without mortar or adhesives
• Suitable for residential and commercial projects
Why Architects and Contractors Choose Pedestal Systems
Adjustable pedestal systems have become a preferred solution for rooftop decks, plaza decks, balconies, and elevated outdoor spaces. Unlike traditional mortar-set installations, pedestal systems provide flexibility, accessibility, and long-term performance.
Architects specify pedestal systems because they create level walking surfaces while protecting waterproofing membranes below. Contractors benefit from faster installation, simplified maintenance, and the ability to accommodate uneven substrates without extensive surface preparation.
Pedestal systems also allow easy access to utilities located beneath the deck surface. If repairs or modifications are required, individual pavers can be lifted and replaced without disturbing the surrounding installation.
For commercial buildings, multifamily developments, hospitality projects, and residential rooftop terraces, pedestal systems provide an attractive finished appearance while supporting proper drainage and ventilation.
Frequently Asked Questions
How many pedestals are needed per paver?
Most pedestal installations use one pedestal at each corner of the paver. The exact quantity depends on paver size, thickness, and project requirements.
Can pedestal systems be installed over waterproof membranes?
Yes. Adjustable pedestal systems are commonly installed over roofing and waterproofing membranes. The elevated design helps protect the membrane while allowing proper drainage and ventilation.
Can pedestal systems be used with porcelain pavers?
Yes. Matrix adjustable pedestals are suitable for porcelain pavers, concrete pavers, natural stone, and deck joist systems.
Do pedestal systems allow water drainage?
Yes. The open space beneath the deck surface allows water to flow freely to drains while helping keep the walking surface dry.
Can pedestal systems be installed on sloped roofs?
Yes. Adjustable pedestal systems are designed to compensate for roof slopes and uneven substrates while creating a level finished deck surface.
Are pedestal systems suitable for commercial projects?
Yes. Pedestal systems are widely used on commercial buildings, hotels, apartment complexes, schools, plazas, and residential rooftop terraces.
What are the advantages of adjustable pedestal systems?
Adjustable pedestal systems provide fast installation, excellent drainage, easy access to utilities, protection of waterproofing membranes, and long-term durability.
What materials can be installed on pedestal systems?
Pedestal systems can support porcelain pavers, concrete pavers, natural stone, wood decking, composite decking, and deck joist systems.
Benefits of Adjustable Pedestal Systems for Rooftop Decks
Adjustable pedestal systems are designed to create level deck surfaces over sloped or uneven rooftop structures.
Can be use for supporting porcelain pavers, concrete pavers, and deck joist systems while protecting waterproofing membranes underneath.
Key benefits include:
• Proper drainage beneath the deck surface
• Protection of roofing and waterproofing membranes
• Fast installation without adhesives or mechanical fasteners
• Easy access to utilities below the deck surface
Where Pedestal Deck Systems Are Used
Pedestal deck systems are commonly used across a wide range of residential and commercial rooftop applications, including:
• Rooftop terraces
• Plaza decks
• Podium decks
• Balcony deck systems
• Outdoor hospitality spaces
• Elevated paver walkways
Matrix adjustable pedestals are designed to support these installations while maintaining structural stability and proper water drainage.
