Trench blocks

Trench blocks are a fast and efficient way to build solid foundations without the need for multiple courses of bricks or blocks. Designed for use below ground, and below the DPC, these large-format concrete or aerated blocks speed up construction and reduce mortar use. Ideal for filling trench foundations, they offer excellent load-bearing capacity and help meet UK building regulations. Thermalite trench blocks also provide improved insulation, reducing heat loss at the base of walls.
