Call 020 8916 2222In modern outdoor design—whether on rooftop terraces, balconies, podium decks or ground-level patios—achieving a level, functional, and long-lasting surfacing solution can be challenging. Key concerns include drainage, maintenance, and the integrity of underlying waterproofing or insulation. Wallbarn’s Universal Adjustable Pedestal provides a superior solution, supporting both paving slabs and timber decking with ease, resilience, and precise performance.
1. Holds Heavy Loads with Ease
These pedestals are built to last. Rated for a standard load capacity of 683 kg with a break point exceeding 1,171 kg, they are suitable for both domestic and commercial environments where heavy slabs, planters or furniture may be used. Such structural integrity ensures peace of mind and reduces the risk of failure during use.
2. Fully Adjustable for Precise Levelling
Each pedestal features a telescopic stem that enables millimetre‑accurate height adjustment—even after the slabs or decking are laid. This flexibility allows installers to account for falls, substrate irregularities or levelling requirements without resorting to trimming or shimming, improving build quality whilst saving labour time.
3. Universal Headpiece—One Model for All Uses
The Universal pedestal headpiece is designed for versatility. With fixed spacer lugs, it accommodates both paving and timber joists, making it a single solution for multiple surfacing types. If needed, the lugs can be removed to suit larger slabs or boards, adding further adaptability.
4. Suited to Varied Climate and Chemicals
Manufactured from virgin fibre-injected polypropylene, these pedestals withstand temperatures from –40 °C to +75 °C and resist salt, acid and alkali attack. Whether in exposed coastal zones, high-altitude rooftops or cold winter environments, their material integrity remains uncompromised.
5. Supports Excellent Drainage and Sub-Surface Ventilation
By raising paving or decking above the substrate, the suspended system ensures full drainage—preventing water pooling and reducing slip risk. It also allows free airflow beneath, limiting dampness and extending the life of timber joists. Moreover, services such as cables, drainage outlets or irrigation pipes can be concealed neatly below the surface.
6. Built-In Noise Dampening
The pedestal headpiece features a rubber acoustic shim, which minimises vibration and muffles noise generated by footfall or movement on the surface. This aspect is particularly valuable in commercial settings—or in residential units where noise transference to interior spaces must be minimised.
7. Simple, Fast, Non-Destructive Installation
These pedestals are freestanding and require no mechanical fixings. That means no penetration of waterproof membranes, making them ideal for warm roofs, inverted roofs and podium landscapes. The lightweight yet stable baseplate (200 mm) also distributes loads evenly across membranes without causing point stress.
Once positioned, the weight of the surfacing—whether paving or decking—naturally holds the system in place; adjustments can be made in situ, enabling rapid ongoing installation and easy removal for maintenance or replacement.
8. Broad Height Range: 35 mm to 380 mm
The Universal range covers 35 mm to 365 mm in one model, with the Universal Extra extending to 380 mm across just three sizes (85–135, 125–215, and 210–380 mm)—reducing product complexity and simplifying stock selection. Height markings every 10 mm on the Extra models further aid precision.
9. Cost‑Effective and Reusable System
Made from durable, virgin polypropylene, the Universal pedestal is designed to last through numerous installation cycles and withstand site abuse. Its suspension design allows surfacing to be lifted and replaced over time without discarding the pedestal—supporting long-term reuse, minimising lifecycle costs and reducing waste.
10. Comprehensive Supporting Documentation
Wallbarn supplies an extensive suite of documentation for Universal pedestals, including technical datasheets, CAD/BIM resources and installation guides. This ensures accurate specification and smooth installation for architects and contractors alike.
