What are pedestals used for?

The construction of hard landscaping areas including concrete paving slabs, porcelain tiles, natural stone slabs and timber, composite and metal decking for terraces, balconies, flat roofs and podium decks.

What are the advantages of using pedestals?

Improved drainage, ease and speed of installation, protection of the surface beneath, future-proofing (can be lifted at any time for maintenance). Lengthen the life of timber joists as they are lifted out of standing water.

How many will I need?

This all depends on your tile size, as well as the area and heights you require. We will let you know the measurements we require to help us calculate the correct quantity and type of pedestals you need.

How are they installed?

They are placed on a flat, hard surface/membrane. No mechanical fixings are required.

What subsurface do the pedestals work on?

A structured surface e.g. concrete or rigid insulation. They are not suitable for placing directly onto non-compacted earth.

How long will they last?

The pedestals are made of virgin plastic and are warrantied for 15 years.

How do I maintain a level surface on a slope?

Our Balance self-levelling pedestals will help provide a level finish to your new deck or paving and can be used to counter slopes of up to 5 degrees. If using our heavy duty Megapads, slope correctors are available.

Do the pedestals need to be fastened to the deck?

No. This is a suspended system. The pedestals are loose-laid – the weight of the slabs or decking hold everything in place – meaning the membrane is not compromised.

Can I place my decking boards directly on top of the pedestals?

No. Decking boards should be fixed to a joist grid which in turn can rest on top of the pedestals.

What additional support systems can I use pedestals with?

Pedestals can clip into our integrated rail system, connecting to a 2m long aluminium rail to support tiles or decking.

What heights do they come in?

Our pedestals come in a huge range of fixed and adjustable heights ranging from 5mm to 1,020mm.

How much gap do I need to leave between my paving slabs?

As standard, our heads are fitted with 2mm spacing but we also have 4mm.

How much weight can these take?

Even our standard Universal and Balance ranges are designed to take up to 680kg. If you have a commercial job that includes large planters or heavy objects, our Megapad range takes up to 2 tonnes.

Can the pedestals break?

We have never had a pedestal fail that was correctly installed since we launched the range in the UK in 2003.

Paving Projects

The Wallbarn Universal Pedestal range is designed for precision and performance in raised paving systems, ensuring a stable, level surface with efficient drainage.

The lugs create consistent spacing between paving slabs and tiles, allowing for effective drainage and reducing water pooling.
This headpiece ensures perfectly straight paving lines for a professional finish
As a suspended paving system, the weight of the slabs holds everything securely in place without the need for adhesives or fixings to the pedestal, or the pedestal to the sub floor.
Rainwater runs freely between and beneath the slabs, preventing standing water and enhancing safety by reducing slip hazards.
For additional support beneath the centre of larger slabs, the lugs can be easily snapped off to accommodate different layouts.
An acoustic shim is included with each pedestal, while a rubber anti-shock pad on the headpiece, featuring a series of ridges, enhances grip and reduces vibration and noise transmission through the pedestal to the deck below.

Ideal for use with adjustable pedestals for paving, the Universal Pedestal range provides flexibility, durability, and ease of installation, making it a preferred choice for both commercial and residential projects.

Decking Projects

The Wallbarn Universal Pedestal range provides a secure, level, and ventilated substructure for raised decking systems, ensuring durability and ease of installation. The headpiece features lugs (fins) positioned towards the edges, creating a 55mm gap to securely house a standard 4″x2″ timber joist, forming a solid framework for decking boards.

Height-adjustable pedestals eliminate the need for cutting furrings, significantly speeding up installation and reducing labour time.
When working with large joists or at points where joists intersect, the lugs can be easily snapped off to accommodate different layouts.
The pedestal system elevates the decking, preventing direct contact with the substrate, improving air circulation, and reducing moisture build-up that can lead to timber decay.
A rubber anti-shock pad on the headpiece enhances grip and stability, while also minimising vibration and noise transmission through the deck.

Designed for use with adjustable pedestals for composite decking and timber systems, Wallbarn Universal Pedestals offer flexibility, reliability, and superior performance for both residential and commercial decking installations.

Maximise Space and Achieve a Flawless Finish with Wallbarn Universal Pedestals

Wallbarn Universal Pedestals provide a versatile, durable, and efficient solution for raised paving and decking systems, transforming underutilised areas into functional, high-quality spaces.

Convert unused rooftops, balconies, and decks into attractive, hard-wearing spaces, increasing the usable footprint of your building. Cover and protect unsightly waterproofing membranes, preserving the integrity of the underlying surface. Create flush ground-floor patios that align seamlessly with internal flooring levels without compromising the damp course.

Raising paving slabs or decking allows water to drain freely, preventing standing water, ponding, and slip hazards. The elevated system aerates and ventilates the surface beneath, helping to prevent moisture-related damage. Cables, water pipes, and drainage outlets can be concealed beneath paving or decking, improving aesthetics and optimising the building footprint, leading to increased yield for developers.

Achieve millimetre-precise height adjustments for a perfectly level surface. Compensate for slab imperfections and create a smooth, even finish. Cope with slopes, multi-directional falls, and significant height variations, ensuring seamless installation across complex surfaces.

Wallbarn Universal Pedestals provide the highest quality adjustable pedestals for paving or decking, delivering strength, stability, and efficiency for both residential and commercial projects.
