Usually, but check the specific product for suitability. Celcon

or similar is recommended for this application, but many standard blocks
should also suffice. However, a wide block like the Celcon Foundation
seriously reduces the amount of labour required, as you can lay the

thickness of foundation in a single course and only split into cavities
above the DPC level.


I always thought you had to use engineering bricks in foundations (I'm
not disputing what you say, just never heard of Celcon Foundation!)


Yes, I thought the reply was - a bit misleading, like saying 'you can
use brick for a fioundation' without saying 'but most people pouitr
