Raising and levelling rooftop terraces, living roofs or rooftop promenades. Our patented DNS® system enables Zoontjens rooftop paving to be quickly and easily raised to the desired height.
We use DNS® pipes to achieve the required height. The precise height of each lifting element is determined using a building laser. The pipe is then sawn to the required height and mounted in a DNS® pressure distribution foot/disc. A support element is placed on top of this, depending on the slab to be used. The result is a level walking surface.
DNS® is ideally suited for paving on living roofs, rooftop terraces, rooftop gardens, cellar roofs, and promenades. DNS® can be used in combination with any finishing material from Zoontjens. A specific support element has been developed for each finishing material, to guarantee a streamlined roof surface. DNS®Large must be used for slabs bigger than 60×60 cm or for raising the level by more than 40 cm.
A special edge zone system supports the slabs near walls or other raised elements. The DNS® edge zone foot is flat on one side enabling it to be placed closer to the edge. The DNS® edge zone disc has an adjustable edge zone strip. This edge zone system provides good slab support and locks the slabs in place.
Spread the load
Forces, weights and loads must be taken into account when constructing and fitting out roof terraces. We will explain this in more detail.
