The light weight and faster build of Aircrete blocks mean foundations can be constructed quickly, easily and cost-effectively, creating an extremely effective moisture barrier with significant thermal insulation properties. Their cellular structure and durability make them a recognised alternative in most below-ground situations.

In a choice of face sizes and range of thicknesses to match typical cavity wall widths, Aircrete blocks can halve foundation build-time, offering considerable labour and money savings.

Aircrete blocks offer considerable improvements in productivity. They're easy to handle so you can build more courses per day which become stable soon after laying. Solid foundations mean less materials on site and their greater workability means they can easily be cut with a hand saw.

Because of their resistance to frost damage and sulfate attack, Aircrete blocks are BBA approved for use below DPC level in soil conditions unsuitable for many other types of masonry unit. Continuous freeze-thaw cycle tests have shown no reduction in strength under these conditions and most blocks can be used in soils up to and including Class 4 sulfate levels, to B.R.E. digest 363.

Aircrete foundation blocks are available in a range of strengths to suit most applications from 3.5N/mm² for general housing needs to 7N/mm² for higher rise buildings. A solid foundation of Aircrete blocks provides a good, level platform from which to build brick and block walls.

Their unique, micro-cellular structure, with millions of tiny air bubbles that do not interconnect, forms an effective barrier against moisture penetration, resisting the passage of water from the surface.

Solid Aircrete foundation blocks reduce heat loss through the floor by as much as 25% compared to other forms of construction and, combined with suspended beam and Aircrete block floor system, can achieve upto a 40% saving in floor U values, offering excellent cost savings through the elimination of secondary insulation elsewhere in the building.

Blocks should be unloaded on to a dry, level surface and covered to protect them from inclement weather.
