Self-levelling Heavy Duty TEST
Mega-Balance
Self-levelling heavy-duty pedestals for paving & decking
Key Advantages
Our 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
- Fully adjustable
- 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 pedestalClose
- 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

Cross-Rail System
The MegaBalance pads are compatible with our cross-rail system, offering extra stability for paving and decking.

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. “

Height Adjustable In-Situ
MegaBalance pedestals can be locked in place, and minor levelling adjustments (which may be required over time) can be made in-situ with the top key.

The "Yellow Key"
Mega Balance are future-proofed and very user friendly, as minor adjustments in height can be made 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 “Yellow 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 Yellow 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.
