Description

Autoclaved Aerated Concrete (AAC) foundation blocks designed as a lightweight, speedy and cost effective alternative to traditional cavity foundation walls.

A solid AIRTEC foundation wall of 140 mm high blocks built two courses high means a faster build, shallower trenches, less waste material, no need for cavity wall ties, less mortar and eliminates any chance of collapsed cavities.

  • Solid foundation walls below dpc.
  • Thin joint construction.
  • External solid walls above dpc.
  • Support for cavity, solid and timber framed walls.
  • Support for block and beam suspended floors.
