What Are Heavy Duty Adjustable Pedestals For Decking & Paving

Megapad adjustable pedestals are the heavy-duty products designed for paving and decking surfaces which will have very heavy loads.

They have a very high weight tolerance, of over 2 tonnes, and can extend up to over 1 metre high. Injection moulded from virgin fibre polypropylene, they are robust and durable in the long term.

They lift the paving or decking off the surface to provide ventilation and free drainage to the roof-deck. They reduce the overall weight of the roof and protect the membrane and insulation layers.

Unsightly objects, such as 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 150mm diameter headpieces have special fittings for either paving slabs or joists for decking applications. The fittings clip into the centre of the headpiece to give either a four-part lug formation to position the corners of the slabs in a uniform laying pattern; housing for the joist to sit loosely, allowing decking boards to be fitted to it. There are no mechanical fixings, the weight of the surface material keeps everything in place.

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.

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.

The height range per pedestal is very large, giving maximum flexibility to applicators. The height can also be locked as the threads have locking nuts at the top and bottom to secure into position once achieved. This prevents heights changing over time as threads move.

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. The weight is effectively distributed and point loading prevented.

If designers are placing planters, art, heavy furniture or expecting very heavy traffic on the suspended surface such as public walkways, jetties and restaurant areas; Megapads should always be chosen.

Reversible

At 115mm high and above Megapads are reversible. When paving up to a wall edge, balustrade or around corners, Megapads can be turned upside down to allow the paving slab to butt right up to the edge of the paving area. The headpiece is 150mm in diameter so serves as an ample base when reversed. And the lug head unit simply fits into what was the base plate.

Quality

Megapad is injection moulded from virgin fibre polypropylene without fillers to withstand extremes of temperature and load.

Each pedestal has a weight tolerance of over 2 tonnes per unit and has been tested to temperatures of +75°C and -40°C. Megapads have been installed in Montreal, Quebec and the Arctic Exploration Station.

Ideal for Decking

The specially designed TD headpieces click into the centre of the head of the Megapads to house a timber joist securely. The distance between the lugs is 60mm which will house a 2-inch joist.

They will lift the joist frame of the deck to prevent standing water affecting the timber over time. Decking boards are then fixed to the timber joist frame no need to cut furrings – simply adjust the pedestal height by hand. The higher clearances from the deck mean that drainage outlets and other services can be covered over without risk of direct contact with the timber.
