Thermalite Aircrete Trenchblock - 355mm

These blocks are specifically engineered for below-ground construction. For above-ground applications, refer to standard Thermalite block specifications.

No, they can be easily cut using a standard masonry saw or a high-quality handsaw suitable for aerated concrete.

It provides positive mechanical locking between blocks, ensuring better alignment and increasing the lateral stability of the trench wall.

Thermalite aircrete blocks are designed for subterranean use; however, they should always be protected from saturation and freezing temperatures during the construction phase.

By providing a continuous layer of insulation at the foundation level, they reduce the thermal bridge between the ground and the building structure.

Check the level of the preceding course. If the base is not perfectly level, the joints will not seat properly; adjust the mortar bed depth.

Use a specialized aircrete adhesive or mortar to bridge small gaps, but if the structural integrity is compromised, replace the block to ensure load distribution.
