I have to use some engineering bricks as well as foundation blocks below ground level. The bricks will be used where i have a bridge over a drain, so will be using some lintels.
I have loads of spare bricks with large frogs in them. Can i use these instead of engineering bricks, or does it have to be engineering below ground level?
