Wallbarn fixed height plastic support pads are manufactured from 100% recycled injection moulded high density polypropylene. They are available in two standard sizes, 14mm and 17mm high. They act as a guide when laying paving, ensuring uniform position. This saves a considerable amount of time in application and gives an attractive finish. It also eliminates the requirement for bedding the paving slabs into mortar, reducing both mess and waste on the roof and the hassle of getting such materials onto the roof. The weight on the roof deck is also reduced.

By suspending the paving slabs, they allow water to run away from the deck underneath. They also help to prevent the build-up of dirt and other material between the slabs. This eliminates ponding on the upper surface of the roof or balcony. They are designed for the simpler , more straight forward suspended roofs. Where applicators wish to increase the height of the cavity at intervals – to work around gutter and service pipes, for example, they can add leveling shims (at 1m, 2mm and 3mm thickness) onto the top of the disk to increase the height.. Although lightweight, they are very tough, with a weight tolerance of 400kg per support pad.

Wallbarn fixed height plastic support pads are made in four quadrants joined together with a small link. They can be easily snapped apart to produce segments of a half or a quarter. This is useful for paving around corners and at the end of runs. This eliminates any wastage of support pads and gives a tidy finish to details, including when paving flush up to walls and parapets.

Further adjustments can be made using shims, which can both fit onto either the rubber or plastic support pads. Plastic shims for placing on the upper side of the support pads come in thicknesses of 1mm, 2mm and 3mm.

Wallbarn also offers a wedge shaped adjustable shim / slope corrector for laying under the support pad.

Wallbarn stackable plastic support pads are ideal for paving to falls and levels since they are designed to stack on top of one another.
