How Wallbarn Universal Pedestals Can Turn Uneven Surfaces into Sleek, Level Decking Areas

December 8th, 2025

Creating a beautiful and functional outdoor living space is a priority for many UK homeowners, landscapers, and contractors. Whether it’s a domestic garden, a rooftop terrace, a balcony, or a commercial outdoor area, the goal is the same: a smooth, stable, long-lasting surface that looks stunning and performs well all year round. However, one of the biggest challenges during installation is dealing with uneven, sloping, or poorly prepared substrates.

Traditional installation methods often require digging, levelling, groundwork, or building a heavy timber sub-frame. These can be labour-intensive, weather-dependent, and disruptive. Fortunately, a modern solution exists — one that makes installation simpler, cleaner, and more adaptable: Wallbarn Universal Pedestals.

This blog explores how these pedestals can transform uneven or complicated surfaces into sleek, perfectly level decking or paving areas — and why they are such a smart investment for professionals and homeowners across the UK.

What Are Universal Pedestals?

Universal Pedestals are adjustable support units designed to hold decking, paving, or other terrace surfaces securely above the existing substrate. The pedestals are engineered to:

Create a level upper surface, even if the base is uneven
Improve drainage by raising the deck or paving off the ground
Allow airflow beneath the surface to prevent moisture problems
Make installation easier and quicker
Offer long-term stability and durability

Wallbarn’s Universal Pedestals are part of a wider system of high-performance support products. Their design is strong, dependable, and engineered to handle the varied conditions often found in British outdoor spaces.

Why Uneven Surfaces Cause So Many Installation Issues

In the UK, outdoor surfaces are rarely perfectly flat. There are several reasons for this:

Patios and terraces often have a built-in fall for drainage.
Older paving can sink or shift over time.
Garden areas frequently have natural dips or undulations.
Rooftop surfaces almost always have intentional slopes.
Weathering can cause movement or uneven settlement.

Trying to install decking or paving directly onto these kinds of surfaces can lead to:

Rocking or unstable boards
Trip hazards
Poor drainage and pooling water
Timber sub-frames absorbing moisture from the ground
Uneven finishes that look unprofessional
Long-term maintenance problems

Universal Pedestals provide a simple, elegant solution that bypasses all these issues.

How Wallbarn Universal Pedestals Solve the Problem

1. Create a Perfectly Level Surface

The adjustable nature of the pedestals makes it incredibly easy to achieve a smooth, level top surface. Each pedestal can be finely tuned to the exact height required. This means:

No digging
No concrete pouring
No need for a fully level ground

The pedestals do all the levelling work for you.

Even on a sloping patio or rooftop, you can build a completely flat deck or terrace with minimal effort.

2. Faster, Cleaner Installation

Timber joists, concrete bases, and traditional support systems can be slow to install and disruptive — especially in small gardens, commercial environments, or hard-to-access spaces.

Universal Pedestals drastically reduce the workload. Installers can:

Place the pedestals directly on the existing surface
Adjust heights quickly
Lay joists or paving slabs immediately

This allows for rapid project turnaround, which is particularly beneficial for contractors working to tight schedules or managing multiple sites.

3. Excellent Drainage and Moisture Prevention

By elevating the deck or paving, Universal Pedestals create a void beneath the surface. This provides several benefits:

Rainwater drains freely beneath the terrace
The decking material stays drier for longer
Standing water is avoided
Air circulation helps prevent damp, mould, and rot

This is especially valuable in the UK’s wet climate, where moisture-related issues are common.

4. Improved Longevity of the Deck or Paving

Because the deck isn’t sitting directly on the ground:

Timber stays healthier
Composite decking maintains its integrity
Paving slabs remain stable
Fixings and fasteners experience less stress
Structural movement is minimised

The result is an outdoor surface that lasts significantly longer — reducing maintenance costs and enhancing long-term value.

5. Built-In Flexibility for Future Access

One of the biggest advantages of an elevated system is the ability to access what lies beneath the surface. If you are running:

Drainage channels
Electrical wiring
LED lighting
Irrigation pipes
Heating systems
Rooftop outlets

You can easily remove boards or slabs to reach the area underneath.

Universal Pedestals provide modern flexibility that old-fashioned fixed systems simply cannot match.

**6. Suitable for Decking and Paving**

Many pedestal systems specialise in one surface type — but Wallbarn’s Universal Pedestals offer compatibility with:

Timber joists
Composite joists
Aluminium joists
Porcelain tiles
Concrete slabs
Natural stone

This makes them a versatile choice for landscapers and contractors who want a multi-purpose solution.

7. Designed for UK Conditions

Universal Pedestals are created with British installations in mind. They offer:

High load-bearing strength
Stability in varied weather conditions
Resistance to temperature fluctuation
Longevity in damp environments
Reliable performance with heavy paving materials

The pedestals are manufactured to meet the practical demands of UK gardens, terraces, and rooftops — from domestic projects to large commercial schemes.

Where Universal Pedestals Are Most Commonly Used

Thanks to their flexibility, these pedestals are popular in:

Home garden decking projects
Rooftop terraces
Balconies
Commercial outdoor dining areas
Hotel terraces and roof gardens
Public walkways
Courtyard areas
Podium decks
Terraces with tricky substrate levels

They are especially useful where weight limits, access issues, or uneven surfaces would make traditional methods difficult or impractical.
