Foundations – Durox Foundation blocks (both homes)



The wall below damp proof course (dpc) is formed using 350mm (wide) by 310mm (long) Durox Foundation blocks. These blocks are a recent introduction into the Durox aircrete range and cater for wide wall constructions offering a block that is easy to handle (11.4 kg unit weight) on site whilst providing perimeter insulation.


Tarmac Durox (310 long x 350 wide x 215 high).

A single layer of foundation blocks using Durox, an aircrete block from Tarmac. Aircrete is a modern construction material with excellent thermal and acoustic properties. It is a versatile material which is able to provide solutions in many applications. Used below DPC in solid walls, these blocks replace traditional inner and outer leaves, wall ties and concrete cavity fill. They can halve construction time and, as the wall stabilises soon after laying, stop cavities collapsing.

Fact 3

During its lifetime Precast concrete will effectively re-absorb much of the carbon dioxide that was used to create it in the first place. Precast units, aggregate blocks and aircrete will ultimately re-absorb the CO2 used to create them.  See more on Tarmac Topfloor for information on staircases used in the house build.
