Airtec Foundation 140mm

AERATED CONCRETE FOUNDATION BLOCKS
(4.8 stars) • 10 reviews
Description:

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 BBA certified, ISO 9001 Quality, ISO 14001 Environmentally and BES 6001 Responsible Sourcing certified.

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.

Applications:
  • Solid foundation walls below damp-proof course (DPC).
  • External solid walls above damp-proof course (DPC).
  • Support for cavity, solid, masonry and timber frame walls.
  • Support for block & beam suspended floors.
Key Advantages:
  • ISO 9001 & ISO 14001 Certified
  • BES 6001 Responsible Sourcing certified.
  • Manufactured to BS EN 771-4.
  • BBA Certified, Category 1 Manufactured.
  • Low Weight.
  • Exceptional thermal performance.
  • Cost-effective solution.
  • Safer handling
  • Easy to cut
  •  100% recyclable, inert and non-hazardous at the end of use
