ᐅ Barbecue Area Walls Height Difference

Hello everyone.
I have started building a wall for our grill area.
The problem is that there is a height difference of about 10cm (4 inches) between the two ends of the planned wall.
The slope was adjusted to the terrace, which is why this height difference occurs.
What is the best way to handle this?
I can hardly put a 10cm (4 inches) thick layer of mortar under the sand-lime brick.

Thank you very much for your advice.

Wow, nice plan. Please be sure to share the project after completion.

And stretch a guideline; otherwise, it will end up crooked despite using a level.

Pictures help. Very much.

Have fun and don’t forget the chalk line, especially for the first layer!

Thank you for all your responses and tips. One quick question..
The blocks have tongue and groove joints.. should they be placed edge to edge, or with a minimal amount of mortar in between? Because they will certainly expand and contract...

Hello Haribobo

First of all, I would install a damp-proof course to prevent rising damp.
Then drill some reinforcing steel into the concrete floor. The wall is freestanding and not very high. The pressure alone will not hold it.
Next, you stretch a string line. Rent a wet saw table (or find someone who can cut the few bricks to the right height for you). Take the different heights from the string line. Let’s say the bottom is 10cm (4 inches), the second brick 8cm (3 inches), the third 6cm (2.5 inches). You lay the bricks so that you level out the slope, and then comes the first “true” course. This one must be perfectly horizontal. Then lay the next course staggered on top of that. Continue building up to the final height.

Hello

Only the first course is set in mortar. The following calcium silicate bricks are glued. You can spread a little adhesive in between. It doesn’t hurt.
