This was a large roof terrace on a private domestic project. The area was flooded and had needed to be re-laid with waterproofing and a significant fall constructed into the deck to allow the often considerable amounts of rainwater to escape the roof deck. The contractor asked Wallbarn for a suitable but cost effective solution so we recommended Wallbarn 9mm rubber supports along with levelling shims. The area was re-waterproofed in the inverted waterproofing method, the membrane being covered with rigid insulation boards and a loose laid geotextile fabric to act as a separation layer .
