Description
Autoclaved aerated concrete foundation blocks.
Features and benefits:
- Freeze/ thaw resistant.
- 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.
