A wall form system of interlocking recycled wood and cement blocks from Durisol has been specified by Atlantic Developments for a new apartment scheme in the coastal town of Ilfracombe.
The system has been used for all external and internal load-bearing walls, as well as the party walls and risers for the 12 one and two-bed apartments. The blocks are manufactured from at least 80% Forest Stewardship Council (FSC) recycled waste softwood, bonded with a proprietary cement/pulverised fuel ash mix.
The interlocking lightweight hollow blocks are dry-stacked and then filled with concrete and steel reinforcing.
According to the company, costs can be kept to a minimum as bricklaying skills are not required. It also claims Durisol provides acoustic insulation and thermal performance values more than twice those of conventional walls. Suited to above or below ground-level construction, Durisol units will not rot or decay and are resistant against vermin and fungal or bacterial growth.
