Accelerating, braking, turning and reversing: these are all actions that are part of a normal driving routine. But imagine the effects these actions could have on a rooftop car park. A properly constructed building can handle this perfectly well, provided it is fitted with a tried and tested, durable rooftop car park system. The Pardak®110 system consists of large slabs with corner sections, pressure distributor pads and tensioning elements, installed on an inverted roof. Applying the Pardak®110 system to this roof structure has proven its worth in practice.
What is an inverted roof?
A rooftop car park is a parking facility on an insulated roof; always with a functional space, such as offices, shops or homes, underneath. The inverted roof structure is the most suitable roof structure for rooftop car parks. An inverted roof which can be driven on is constructed as follows, from the bottom up: (1) waterproofing membrane, (2) thermal insulation, (3) Pardak®110 system. The waterproofing membrane of an inverted roof is placed under the insulation layer. Each part of this structure has its own function and together they bring many benefits.
Separation of driving surface and waterproofing membrane
The advantage of the inverted roof is that the roof skin is separated from the driving surface. The insulation is in between the two parts to ensure excellent protection of the waterproofing membrane against thermal and mechanical loads. There is no risk of the seal being damaged by direct contact with the driving surface.
The Pardak®110 system consists of large slabs with corner sections, pressure distributor pads and tensioning elements. The tensioning element is the most important part and is unique. The effect of tensioning the slabs is that the vertical and horizontal forces caused by car movements are absorbed and distributed across the slabs. Together with the other components of the system, this ensures a stable surface.
Distribution of forces when driving
The corners of the Pardak®110 slabs rest on pressure distributor pads. Four slabs come together on one pressure distributor pad. The pressure distributor pads serve to absorb and distribute the vertical forces created by cars driving on the rooftop car park.
Optimum water drainage for a dry driving surface
The pressure distributor pads have been designed to create a cavity under the slabs through which water can drain away quickly. This ensures that the driving surface is almost always dry or dries up very quickly. The cavity under the slabs can also be used for charger cables or other cables or pipes.
Removable, modular, circular
Because of the inverted roof structure, the waterproofing membrane is very well protected and has minimum exposure to sun, rain and wind, resulting in a very long service life. And if there is ever a problem with the roofing or the insulation, these layers are always easily accessible. The Pardak®110 system is removable and modular. It is easy to take out and replace. A new, additional parking area on the roof can easily be incorporated as well.
