DUROX Foundation

Aerated Concrete Foundation Blocks – DUROX Foundation blocks

Overview

Durox is a modern construction material, whose versatility, light weight and thermal properties make it ideal solution for a wide variety of applications in all types of buildings. Durox foundations blocks are produced specifically for the use below DPC to replace traditional cavity filled walls. 

Durox Foundation blocks replace the inner and outer leaf, wall ties and concrete cavity fill associated with traditional build methods. Construction time can be halved compared to cavity construction and the Foundation wall becomes stable soon after laying, allowing the early start of above ground work.

In response to increasing standards of energy efficency, Durox Foundation blocks 310 x 350 x 215mm have been introduced. These blocks can accomodate cavity walls above ground of up to 350mm width wilst maintaining a conventional block bedding height.

Durox Foundation can be used to support cavity, solid walls, or frame constructions.

Both strengths of our 310 x 350 x 215mm Foundation Blocks are below the 20kg manual handling weight.

Where can DUROX Foundation be used?

Solid walls below DPC

Foundation blocks are used below ground in soils up to Class DS-3 sulphate level for the 7.3N/mm2 product and Class DS-2 for the 3.6N/mm2 product.

 

Why use DUROX Foundation?

How are Durox foundation blocks installed? 

For below ground use (excluding work in retaining or basement walls), Foundation blocks can be used with unfilled vertical joints, provided the blocks are built with their ends closely butted together to restrict the passage of vermin. This advice is consistent with the guidance given in BRE information paper IP7/05. The blockwork should be set out to achieve adequate block bonding at corners.
