This is a grey thermalite aircrete trenchblock supplied in a convenient grab pack format. With dimensions of 440mm length, 300mm width, and 215mm height, it is designed for constructing below-ground walls and foundations where speed and ease of handling are required.
Typically used to form the base of external and internal cavity walls, these tongue and groove blocks help reduce labour by minimising the number of courses needed. The lightweight nature and size make them suitable for efficient installation on site, supporting the construction of solid and insulated groundworks.
