Bricks - how stable?

[RBK]

Hello!

I'm about to start building my 60 cm high brick wall for the greenhouse soon.

At the bottom, there is a concrete sill, a layer of leca, and then bricks. Everything will be mortared with weber base 222.

To the question, I want a bit of protrusion on the brick from the leca row, does sacrificing 16 mm of 108mm (Danish DNF measurement) affect the stability significantly, or will it be stable enough that these 16mm aren't "needed" from a strength perspective? So the bottom row of the wall will then have a 92mm mortared surface.

Grateful if a constructor or expert can answer!

Hello!

I will soon begin my 60 cm high brick wall for the greenhouse.

At the bottom, there is a concrete base, a layer of leca, and then brick. Everything is laid with weber base 222.

To the question, I want a slight protrusion on the brick from the leca layer, does it significantly affect the strength if I sacrifice 16 mm of 108 mm (Danish DNF measurement) or will it be stable enough that these 16 mm aren't "needed" from a strength perspective? In other words, the bottommost row of the wall will have 92 mm of masonry surface.

I would appreciate it if an engineer or expert could answer!

The answer is stable as heck, whether it withstands an autumn storm remains to be seen!

Where does the wall end up?

Where does the wall end up?

If you see how the stone is positioned, it's 9 layers up, total 60 cm.

Well, I mean the greenhouse wall

Hello!

I'm about to start building my 60 cm high brick wall for the greenhouse.

At the bottom, there is a concrete foundation, a layer of leca, and then bricks. Everything is built with weber base 222.

To the question, I want a little protrusion on the bricks from the leca layer, does it significantly affect the strength if I sacrifice 16 mm of 108mm (Danish DNF measurement) or will it be stable enough that these 16mm are not "needed" from a strength perspective? So the bottom row of the wall will have a 92mm built surface.

I would appreciate if a designer or expert could answer!

It will work just fine. However, snow cannot lie against the brick in winter, a plinth is needed.

The greenhouse dimensions are (LxWxH) 464x314x290. 290 then includes the 60 cm brick wall.

It will work perfectly fine.
However, snow can't be against the bricks in the winter, a base is needed.

Great! Since it's on a slight slope, the brick is at ground level in one corner. I'll have to be a bit creative there.
