Foundation (trench) blocks 7.3N/mm² to BS EN 771-3

Products / Foundation (trench) blocks 7.3N/mm²
Our foundation blocks have a 300mm wide dimension which allows for a 100mm inside and 100mm outside skin of blockwork or brickwork to be built, leaving a 100mm cavity.

Wider cavities or thicker block widths can be accommodated by using the F350 foundation block laid with the 350mm dimension across the wall.

Foundation blocks are available in Stowlite medium dense 7.3 N/mm².

When F350 Foundation blocks are laid 300mm wide there are 26 no. per m². Where they are laid 350mm wide there are 29 no. per m².

When F440 Foundation blocks are laid 300mm wide there are 20 no. per m².

All products available ex works. Prices on application. Please contact the sales office for further information and a quotation. For information on packaging click here.
