Airtec Foundation 140mm

AERATED CONCRETE FOUNDATION BLOCKS

Our 140mm Airtec Foundation blocks are designed as a lightweight, easy to lay, speedy and cost-effective alternative to traditional cavity foundation walls. A solid Airtec Foundation wall of 140mm high blocks built two courses high 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 these lightweight Airtec Foundation blocks enhance thermal integrity throughout the build especially if used in conjunction with Airtec walls and floors blocks. Hand-holds are also provided at the ends of the blocks for easier, safe manual handling.

All Airtec products are ISO 9001 Quality and ISO 14001 Environmentally certified and with the highest possible BES 6001 Responsible Sourcing rating of ‘Excellent’

In common with all other Airtec blocks, these lightweight large concrete blocks offer the very best possible dimensional tolerance category of 'Thin Layer Mortar B' (TLMB) but are perfectly suitable for conventional 10mm mortar joint construction.

With all aerated concrete in the UK, the surfaces of the building blocks may contain a random number of larger natural air bubbles/cells on the block surface due to an unavoidable consequence of the manufacturing process. These large cells are perfectly normal and are not a defect and do not detract from performance in any way.

    • A range of a wagon sizes are available, with or without pallets. Ring your local Sales office for further details.
    • Block weight is at the equilibrium moisture content of 3% by weight
    • Pack weight allows for maximum moisture content when packed, actual delivered weight will be less
    • m² per pack figure based on the inclusion of conventional 10mm mortar joints
    • Health & Safety guidelines recommend that precautions be taken when using blocks over 20kg in weight.
