The speed-limiting slabs from Zoontjens make it possible to simply integrate speed bumps in any Pardak® 110 parking roof. The convex protruding shape of the speed limiters discourages fast driving, thereby contributing to rooftop safety.The speed bumps achieve the required width by combining two speed limiters with a rounded-off end section together with a number of straight model slabs. The speed limiters are produced from precast concrete. The slabs can be installed during the laying of the Pardak® 110 system or subsequently. The characteristic diamond pattern of the Pardak® slab is continued onto the speed limiters. Once tensioned in position, this makes them an integral part of the parking roof.
