This ultra-thin Wallbarn 5mm PVC Pad elevates decking while preventing direct contact between the membrane and heavy paving slabs. It serves as a protection layer against surface damage from scaffolding, plant pots, or garden furniture. The pad is a 150mm diameter flat PVC disc. An optional polypropylene cross-spacer can be added for slab spacing; it's not needed for decking. It protects the membrane underneath from touching slabs and prevents surface damage. Installation is easy and mortar-free. The pad is 5mm thick with a 150mm diameter. It has a lug width of 2.2mm and lug height of 15mm, and can bear up to 8,000KG. Shaped flat on both sides, the slabs' weight secures the surface, reducing roof load and eliminating mortar use. This makes installation fast, cost-effective, and clean. Optional cross-spacers are available in 3mm, 4mm, or 5mm.. Wallbarn 5mm PVC Pad Black
