5mm RUBBER DISCS

Where applicators have very restricted height thresholds, Wallbarn can offer a solution in the form of 5mm thick rubber discs laid in conjunction with cross spacers.

The solid circular discs are made from PVC with a smooth finish.

Separation of each slab is achieved with a loose laid cross spacer. These are available in various thicknesses and further details are given below.

3-8mm WEDGE SHAPED RUBBER DISCS

Wedge shaped discs are also available. They are similar to the 5mm discs but wedge shaped instead of being flat. They slope from a thickness of 8mm at the highest down to 3mm.

On areas where there is only a very small threshold, it is possible to use two of these wedge shaped discs together to act as an alternative adjustable pad. More a shock absorber or membrane protection than an actual support, they can be slid towards or away from each other to create different thicknesses, achieving a range from 3mm (where one has been used on its own, up to 11mm, where two have been stacked on top of each other completely.

A better use for these items is as a slope corrector beneath fixed height support pads. Simply placed onto the deck with a plastic or rubber ring loose laid on top without fixings, they can take out the fall in the deck to ensure that the support pad is completely vertical and straight, and the paving does not tilt in any way.

CROSS SPACERS

The discs described above are all flat pads, without integrated separation lugs. Where they are being used for paving, it is advisable that loose laid cross spacers are placed on the centre of the disc to achieve the accurate, straight paving line.

These polypropylene two-part pieces are slotted together to create a small cross shape, which can be fitted into the junction between four paving slabs to ensure they remain straight and in place. Therefore, regular paving can still be achieved even when using flat discs.

The cross spacers are available 3mm, 4mm and 5mm thick. All of these sizes will ensure adequate drainage, the gaps between the paving slabs depends more on the wishes of the designer.
