The wall we are about to build here will weigh in at over 70 tons, including
the stone and the mortar holding it together.
Although that weight
XXXXXXXXXX, a section of just one yard will have to support one ton of
weight.
So the foundation has to be XXXXXXXXXXXXXXXXXXXXXXXX.
Otherwise
the wall slowly sinks and cracks will appear, which get wider and wider...until
the wall falls over!
As I've said all through this
Publication...XXXXXXXXXXXXX XXXXXXXXX should be...it depends on rainfall,
freezing and how XXXXXXXXXXXXXXXXXX, and how heavy the wall is.
Lastly,
never lift anything unless you are used to heavy lifting...again if you are
unsure, seek local advice. Small rocks aren't heavy, but rocks like these in the
foreground are.

Building natural stone walls are easier because XXXXXXXXX of stone are
XXXXXXXX and therefore if you go a bit wrong it won't be noticed so much.
But
even a wall like this will take some practice. The trick is to find
XXXXXXXXXXXXXX.
If the stone you use is of different thicknesses, first you
need to XXXXXXXXXXXXXXXXXXXX.
Study this wall and you'll see how it's done.
In some places two stones have been laid next to one stone. In other words two
stones together make up the same thickness as the one next to them.
Walls are
built in layers...these layers are called "courses".
There are three main
ways of building natural stone walls.
XXX, which means the stones XXXXXXX
themselves...but that's another XXXXXXXXXXXXXXXXXXX..."drystone
walling".
Then there are walls that are XXXXXXXXXXXXXXX with 6 to 1
mortar...which XXXXXXXXX...and lastly there are walls that are held together
with XXXX between the stones instead of XXXXX.

Even though, with this method, you use more XXXXX to XXX, the mortar soon
mellows with the stone and you focus on the stone.
Note from Paul
Dyer...this is the actual wall referred to in the first image, now nearly
finished.

Again you can create a flat top by using a string line or a spirit level.
Levels though will be fairly rough if you're using very irregular rocks or
stones.
It's easier to keep to levels under control if you use XXX
XXXXXXXXXXXXXXXXX stones.

Although this looks the same, it's actually held together with earth!
