Floating Foundation Installation
Fix the 20mm thick perimeter isolation board on concrete up-stand all around the proposed floating foundation. PIB tear must be on top with tear slot facing towards floor to be poured.
Roll out the rim, cutting the low density fiber glass to the required length and to match foundation dimensions.
Lay 18mm marine plywood on top of rim materials, staggering the joints and securing together using junction plates spaced at 600mm as shown in the approved details.
Cover the plywood with two layers of polyethylene 1000ga. Overlap seams minimum of 150mm, extend polyethylene sheet up and staple to the up-stand.
Place the required reinforcement as per the approved method statement and pour the floating slab as per approved procedure and project specifications.
After concrete has cured, removed PIB tear strip and excess polyethylene sheet at slab perimeter. Fill slab perimeter using the bitumastic sealant as per manufacturer’s instruction.
