Self-levelling adjustable pedestals for paving and decking

Wallbarn

Mega-Balance
Self-levelling heavy-duty pedestals for paving & decking

Key Advantages
Wallbarn’s MEGA BALANCE self-levelling pedestals are specially designed for heavy loads and offer a huge height range (up to 1025mm). The self-levelling headpiece is used to accommodate differences in the deck surface below the pedestal.

• Achieve stunning finishes • Suspended system • Top key system for in-situ adjustments • Superior quality • Compatible with cross-rail system for additional support • Suitable for paving slabs and timber decking • Self-levelling and fixed-height in same pedestal • Available in heights from 25mm up to 1025mm

For Paving
• Self-levelling headpiece incorporates 4 x positioning lugs (fins) laid out in a crucifix formation set towards the edges
• The headpiece also comprises 4 x separate parts created to allow up to a 5% or 2.86° slope correction in all directions
• The mechanism at the bottom of the headpiece allows smooth movement and positioning of the paving slab
• The lugs (fins) separate paving slabs and tiles on the headpiece to allow sufficient drainage between slabs
• This creates a uniform paving line so the slabs are laid completely straight
• A rubber anti-shock pad slots onto the headpiece over a series of ridges to give better grip to the slab and help insulate against vibration and noise travelling through the pedestal to the deck beneath

For Decking
• The lugs (fins) are set out towards the edges of the headpiece giving a 55mm gap between them to house a timber joist
• Decking boards are then fixed to the timber joist frame no need to cut furrings – simply adjust your pedestal height
• The auto-correcting head makes installing decking systems much faster than traditional methods

Clip Head for Rail System
The Mega Balance pads are compatible with Wallbarn’s cross-rail system, offering extra stability for paving and decking.
The Mega Balance pads can be used to join two separate rails as shown here

Fixed Height & Self-levelling
Mega balance pedestal is available as both a fixed head and self-levelling headpiece in the same unit by using “The Grey Nut”.

The pedestals comes as a self-levelling unit as standard. Fix The Grey Nut into the centre of the headpiece between the marked sections and press down hard.

The arrows on The Grey Nut line up with the existing black moulding in the central section of the headpiece.

The headpiece then becomes locked and fixed. Both layout options are thus available in the same pedestal, giving greater flexibility to the installers.

Retro-adjust Height - "The Key"
Mega Balance are future-proofed and very user friendly, as minor levelling adjustments (which may be required over time) can be made in-situ without having to lift the slabs.

Often suspended paving areas can have slabs starting to rock or dip, as the structure moves through expansion or traffic and other forces lead to the upper surface becoming unlevel. “The Key” is the solution.

Instead of having the physically lift the affected slabs, twist the thread on the pedestal, replace the slabs and checking for the correct height; users have the major advantage of using The Key. By placing the key into the centre of the headpiece users can lift the height of the pedestal marginally to recreate the flat, correct level for the slabs.

This is a much faster process to achieve the correct paving level and crucially has major health & safety advantages. Instead of having to lift heavy paving slabs repeatedly, operatives can ensure perfect upper level of paving without risk to both their own welfare and from dropping a slab onto the surface / subdeck.

Mega Balance offer flexibility, speed and safety to the FM teams and owner alike.

Balance Self-Levelling Pedestals

BALANCE self-levelling pedestals are specially designed to accommodate differences in the deck surface below the pedestal. Made from virgin fibre polypropylene, they are available in heights from 25mm up to 392mm.

There can be blemishes and ridges in the sub-deck e.g. felt overlaps or changes in the thickness of a paving slab which can make the upper surface uneven. The BALANCE adjustable pedestal pivots at the head so that the upper surface is completely flat, bringing greater stability and a more luxurious finish to the paving or decking area.

Hide unsightly objects. Cables, water pipes and drainage outlets can be concealed underneath the paving slabs or decking, improving the aesthetics and optimising the building footprint, bringing more yield to the developer.

Headpiece

The 120mm diameter headpiece can support both paving slabs and joists on timber decking applications. Rainwater can run between and under the slabs or decking, so there is no standing water left on the surface. This improves health & safety as it makes the surface area less slippery.

The headpiece has been created to allow up to a 5% or 2.86 ° slope correction. The optic-type mechanism moves in all directions, so the head finds its own flat level.

The lugs are positioned to hold either the corners of four slabs in place or house the joist between them for secure placement but allowing movement. There are no mechanical fixings, the weight of the surface material keeps everything in place.

The auto-correcting head makes installing decking systems much faster than traditional methods. The mechanism ensures smooth movement of the head and positioning of the paving slab. Slips and sharp tilting are avoided owing to the superior design and solid manufacture.

A rubber anti-shock pad is installed on the headpiece to give better grip to the slab or decking and help insulate against vibration and noise travelling through the pedestal to the deck beneath.

Stem

The telescopic stem allows hand adjustment in height when the slab or decking is in place, leading to labour savings and improving health and safety.

Baseplate

The base plate is 200mm diameter, which gives effective weight displacement when paving / decking onto surfaces such as waterproofing membranes and insulation. Fins running from stem to edge of the baseplate guards against point loading down the central column.

Low threshold

Our 25-50mm Balances have been specially designed to make installations at very low height thresholds easier. A small “PULL” tab on the side enables installers to open up the pedestal and set the unit at different heights, depending on which sized notch they decide to connect. Each setting is 5mm higher at each step.

By changing the setting of the notches installers go from 25mm up to 50mm in height and still have an ample range of adjustment through the thread.

Quality

This unique design is robust, stable and durable. The pedestal is injection moulded from virgin fibre polypropylene without fillers to withstand extremes of temperature and load.

Each pedestal has a weight tolerance of 683kg per unit and has been tested to temperatures of +75°C and -40°C.

Ideal for Decking

The lugs (fins) are set out towards the edges of the headpiece giving a 55mm gap between them to house a timber joist. Decking boards are then fixed to the timber joist frame no need to cut furrings – simply adjust the pedestal height by hand.
