The tongue and groove design of the Aircrete Trench Blocks makes them quick and easy to fit.
Thermalite Aircrete Tongue & Groove Trenchblocks can be used in place of a cavity wall with a heavy concrete brick or block infill.
These blocks are ideal for concealed use rather than in facing projects due to their grey colour.
Fire Resistant and manufactured to British Standards.
