Paving bricks vs. Wall bricks. Use them both?

[Patrick]

I have a pile of paving bricks and wondered if they could be used for a Garden wall. Would make it double skin with the  inner wall being paving bricks and the outer (outside facing) wall being reclaimed victorian  red brick. I have them around from dismantling the old building but not enough to do the entire wall with them.

Any disadvantages using pavings bricks?

any problems?

I'd say no. The blocks have no frog so the resultant wall won't be very strong.

OK. Understand. Only that the reclaimed red bricks from the old house got none either

 

So you would say in both of them, mortar don't stick too well?

I think these would be fine for a garden wall.  Give them a proper clean and encourage whoever is laying them to choose the best side.  Use a lime mortar.

The bricks from the chimney breast in the bungalow I dismantled didn't have frogs and they lasted ninety odd years and the chap who took them on Freegle used them for a garden wall.

What's the advantage over cement mortar? I'm comfortable mixing that but never used lime.

Lots of theories as to the why of frogs:

Softer - the mortar should be softer than the brick - more environmentally friendly, better colour / weathers better, traditional / heritage, possibility of reusing bricks.  Makes the mix workable.

 

You could use 1:2:9 cement:lime:sand.
