ZWH®
wind corner
slab

Fixed-form ballast without slab carriers for roofs with loose-laid roofing.

Flat roofs with loose-laid roofing are usually ballasted with coarse gravel. Because of the necessary wind resistance, fixed-form ballast is placed at edges and corners. Concrete slabs on rubber slab carriers are a commonly used solution in such cases. However, this combination is labour-intensive and costly.

Zoontjens supplies the easy-to-handle ZWH® slab in sizes 30×30 and 50×50 cm. These slabs with brushed lugs can be placed directly on the roofing. The ZWH® slab is complies with health and safety requirements and Dutch NEN standards.
