Product Overview
This 300mm high-performance aircrete trench block offers a compressive strength of 3.6N/mm², making it ideal for below-damp proof course (DPC) foundation walls. It supports single-leaf construction and enhances both thermal and moisture performance. With a typical thickness of 300mm, it effectively replaces cavity wall construction, streamlining the building process.
