To counter issues associated with concrete slab construction in Auckland’s ‘expansive soils’, Dempsey Wood developed the Super Slab system, in association with Harris Foster Consulting.
These polystyrene raft slabs are cheaper and quicker to install than traditional blockwork foundations. Other benefits include their strength and durability and excellent insulation properties.
Particularly good for sites with low ground-bearing capacity, raft slabs can be accommodated on most sites by using methods such as certified cut-to-fill, or supporting the slab on driven piles.
Dempsey Wood has the expertise to provide an assessment of the best foundations and construction techniques for your site. We offer a complete package: to excavate your site and retain and complete to slab level – all ready for the builder.
