Levels question

[r44flyer]

Hello all,

I'm planning a patio. The ground slopes away from the house gently so that when level with the correct fall there is a height difference of about 3-4 courses of bricks at the front edge of the patio. This small wall will be built so that the paving will sit on it, ie. just lipping over them.

However, the wall isn't straight but is in two L shapes, between which are steps, recessed into patio if you like, and so will have sections perpendicular to the house in the direction of the fall.

Should I build the wall absolutely level and take up the difference in the fall along the length of the perpendicular walls with a thick layer of mortar? It would be approx. 40mm at the 'high' end. The only other way i can see to do it would be to build the wall with a slight fall, but that would give a sloping face at the edge of the patio, which can't be right.

I hope i have explained that well enough.

Many thanks.

where the patio lips over the wall i guess the wall must be level at that point
where the recess for the steps is the wall should follow the plane of the patio i.e. 1:60 fall or whatever you have
it looks cat if you have a wedge shaped mortar joint
plus your steps should have a slight fall out each anyway

Thanks LLL.

Where the walls meet at the corners, obviously one is level, one is on the fall, how do I join them? They won't interlock will they? Do I just mitre each brick and mortar the walls together?

its hard to explain in wroiting but a brick can be level along 1 arriss and have a fall on another 1

If perhaps they do interlock but then the next brick uses the width of the joint to make an angle? So you'd have a few wedge shaped mortar joints between bricks?
