Airtec Foundation 140 blocks are a 140mm high block designed as a lightweight, easy to lay, speedy and cost-effective alternative to traditional cavity foundation walls. A solid Airtec Foundation wall means a faster build, shallower trenches, less waste material, no need for wall ties, less mortar and zero chance of collapsed cavities. The excellent thermal properties of Airtec Foundation blocks enhance thermal integrity throughout the build especially if used in conjunction with Airtec walls and floors.

Hand-grips are provided at the ends of the blocks for easier, safe manual handling.

Airtec Foundation Trench Block 620 x 140 x 350mm
