Proposed workshop build

[Jones]

Motar is mainly used to keep the bricks apart not glue them together. A NHL 3.5 mix will be a direct replacement for a cement mix and is specified quite often nowadays for face work . You can get it in builders merchants easily or get bagged premix online. It's best to mix dry then add water to give a slightly dry mix ,rest for 5 mins then mix again to give the right consistency . No plasticizer or additives. It's stickier than cement so you may have to scrape the back of the mixer halfway through.

How critical are engineering bricks in this situation?

 

[Jones]

Engineering bricks have better strength and can be used where they will permanently wet. If neither of those apply then normal bricks should be ok.

As it's on a concrete pad 50mm above ground surely I can use a more decorative brick then?

 

[Jones]

Yes
