Hello and welcome this is Carl the Landscape
Guy. Today is about the creation of a mortared
sandstone wall and the natural stone expert Vangjeli has agreed to give a few tips. We will look at what he’s doing and I thank
you for following along. This wall is going to be 2.5 meters high functioning
as an enclosure on the side of the patio and of course this height can only be managed
by using lime mortar. The weird shaped stones make building the
walls a challenge. Therefore, I am happy that Vangjeli will show
us how it works. Last time he prepared the stones for this
wall and cut them, I will link the video up here and at the end again. Below in the video description there is more
information about this project. Vangjeli, would you be so kind as to tell
us what is important. Here we build a natural sandstone wall, it
is a pretty soft red regional sandstone and there are a few things to look out for. We work with continuous joint lines. But they don’t run all the way through. After 3-4 stones we jump with the line up
or down by setting a bigger or smaller stone. We are using strings to help get a nice, straight
wall. On the wall, we set a vertical string on each
side of the wall. Then you can move your horizontal strings
up and down as you need. So the next stone is to be set here and we
want to jump up with the level. We will use a thicker stone. Using different stones in sizes throughout
the wall gives it that special, natural, ancient look. Ok let’s make the stone fit the spot. But you’re too far in here with that stone. Because it keeps me from setting a nice big
one on this main side here. So you either have to cut off the back of
that one or use a thinner stone that’s not that tall. Also it’s important that all stones have a
slight slope down towards the inside of the wall. Ok so let’s prepare a stone. Of course we could still make one the same
height but we don’t have to, so we want to take a higher stone now. We could now take almost any size of stone,
because we start with a new height. Here we see two stones that have the same
height. Three to four stones can be set well at the
same height. One alone is usually not as nice, except if
it’s really a big one that looks good by itself. Here we have the example that the stones in
this row are deeper over to the right. But don’t try to finish the row by installing
any sloping stones in between. The stones must always be set horizontally. I do that just by eye and not with a spirit
level or anything. It has to look good. Do not build like that, it’s ugly. The two strings help to align the stones properly
100% straight. If I am standing by the wall like this I have
to be able to see both, the top and the bottom cord too. You can also use one string, that’s what we
do on the back side which won’t be visible really later. But up front it’s better with two strings. And then you support the big stones with little
ones in the middle. And don’t forget the mortar, that’s very important. By the way many people say these type of walls
don’t have to be so wide. A wall must be 50 cm wide. Because the stones have to overlap in the
middle. You need at least 3 to 4 big ones per square
meter off wall that overlap well. And if you make it only 30 cm thick, we don’t
have enough room for overlapping the stones. For example, like here this one, it goes over
here and that helps to last very long. If a wall is only 1.2 m, that’s a different
story but here the customer wants a 2.5m high wall and i highly recommend 50 cm of width. People want to save stones and mortar but
that’s nonsense. Of course we have scrap stones from shaping
the rocks. But whatever lies around down here we will
use in the middle to fill up the gaps. All the little ones we do not need come in
the middle. Nicely mixed with enough mortar to make it
sturdy and support the big stones. Now let’s continue here. I chose this one because it has the right
thickness and fits pretty good up in here. We watch out not to change levels with each
stone meaning to jump up and down. Because then we will have problems with the
next layer. So we keep this part of the row relatively
level. So first i bring it to the right length. Only a little comes off. I do that by eye. Now take the humps off so that it lays nice
and flat. Smoothening the edges a bit and then put it
in place. And see how nicely it fits. Yes, that fits exactly where we want it. We need a little more mortar because that
is not enough. And here we go, it’s nice and solid and
this row is finished on that side. Here we have a very good one. I chose it because its very thin and it fits
perfectly, I think. I check the face of the stone, which is gonna
be the front, by sighting along it. I carefully break the corners. But I have to be careful because otherwise
it will break somewhere else since it’s so thin. So now we can put that in our wall. Of course some mortar underneath. By the way the mortar has to go more in the
back because if we push the stone in place it should not come out the front. This customer wants a wall with open joints,
meaning not filled. This one here is only 1 cm to big. Sometimes I’m not sure and before I take off
too much I’d rather hold it in place to check. I am taking the thinner side off a little
bit. I have to be careful with this one. Oh too late. But it’s not too bad. We will still put it in there anyway? Thats the great thing about natural stones,
we can just shape them different and it will still look very good. Here I also take off a bit here so that the
back sits a little lower. I am taking the corners out a little and we
can set it like this. I hope
my tips help you to get your project done and I hope you like the video. Thanks for following along today and see you
next time.
