Choosing the right walling stone

Friday, 14 June 2019 13:50:28 Europe/London

The choice

Choice is good, we love choice. But sometimes when there is so much to choose from picking the right option can be daunting, especially when you may be relatively new to the field. Building a stone wall is no exception. With so many types of stone and so many grades of stone, finding the right stone can be a headache. This article is here to help by asking a few questions to ascertain what option is best for you.




The first thing to consider is restrictions. Do you have a bed depth limit i.e. can you only allow your stone to go back into the wall 6” (150mm) for instance. Once you have decided what bed depth to go for its time to move on to preference. Are you after a random rubble appearance or something a little more coursed? See example on left.

Narrow it down

Once you have decided these factors its time to decide which stone to go for. Each stone has different colours and properties. At this point it may be worth looking at some of the types of stone available at Lantoom. We have slate, granite, limestone and sandstone walling options, we also have sample panels for those who would like to see the stone in person. Applying all these factors you should come to just 2 or 3 options and from there the choice is up to you. If you still are unsure give us a shout our staff are happy to help.

History of quarries in England

Thursday, 30 May 2019 10:40:04 Europe/London

Stone Age

With our reliance on render and brick for building structures, the use of stone and therefore quarries has decreased throughout the modern age, but this wasn’t always the case. If we were to journey back to 4000BC we would find a different story. No, we wouldn’t find Fred Flintstone sliding down a dinosaurs neck whilst screeching Yabadabadoo. Instead we would find the early hunter-gatherers. Stone, namely flint, that was quarried in “The stone age” and was mainly used for hunting and creating tools.



The Invaders

This trend followed us through 1600 years until we arrived at the bronze age (2400BC approx.) Tin and copper was now our preferred material for creating tools and weapons. Then came the Romans in around (40AD) they brought with them the knowledge of building houses with stone as well as long strait roads. The Romans left after about 400 years and unfortunately so to did a lot of there know-how and technology. Finally when the Normans invaded in (1066AD) they built castles, cathedrals and churches out of stone.

Modern day

This brings us through to the modern day. Stone was such and important part of our history and still plays a key part in creating lasting buildings to this day. It seems stone has lasted the test of time and still proves the best choice when it comes to building a better world.

Build a better moon

Friday, 8 March 2019 11:19:06 Europe/London


There has been a lot of talk in the last few years about colonizing the moon. Of course this has thrown up a lot of debates - Do we have the right to own parts of the moon? How will we get people there and back? Would it even be worth the effort? As someone who is very interested in stone a questions which springs to my mind when talking about this subject is; what will we build the houses out of?



Potential issues

Space travel takes a lot of energy, the heavier the craft the more energy will be needed to get it out of the atmosphere. Stone is by nature heavy and therefore, I find myself asking: would it really be practical to transport such heavy material to the moon?

Reaching for the sky

But if we couldn’t bring stone to the moon then the obvious answer would be to use moonstone. But would moon rock be any good as a building material? Yes actually, cement and concrete can be made out of moon material and would actually be even stronger then the cement and concrete we use back home, this coupled with the lower gravity would mean we could build taller structure then what we are used to on earth, the sky is no longer the limit.

Chasing away the winter blues

Friday, 18 January 2019 08:54:31 Europe/London


The Winter blues are in full swing, its that time of the year after the exciting build up to Christmas, but before the weather gets warmer and the days longer. Its the time of year when you leave for work in the dark and come back in the dark and its this time of year when you may find yourself twiddling your thumbs for ideas on what to do next.




There are ways to satisfy your longing to start a project. One such a way is to update your fireplace. When entering a room your eyes natural draw to the fireplace, so it makes sense that the area looks smart to really showcase the room. Having granite lintels or stonework around the fireplace can give off a great impression when entering the lounge. Of course it’s impossible to talk about a fireplace and not mention a hearth. Installing a natural slate or granite hearth can complete the look.


Moving away from the fireplace you may wish to consider installing some internal paving, perhaps you are fed up with the haggard old vinyl floor which has seen better days. Why not consider a natural stone product like slate to add a little character to the room.

Any one of these projects would be ideal for chasing away the winter blues.

Stone skimming championship

Friday, 21 December 2018 09:07:59 Europe/London


Picture the scene; you are at the beach with your son, who gleefully comes up and declares he has managed to skim a stone twice along the water’s surface. Instead of congratulating him on his feeble effort, what is the first thing we all do? We try and outdo him. What is it about stone skimming that brings out our competitiveness?

The sport

The record

In 2018 the best skimmer was Peter Szep from Hungary with an impressive 43 skips in a single throw. However the world record is held by Kurt "Mountain Man" Steiner, who skimmed an amazing 88 skips back in 2013. If you fancy giving it a try, you can register today to take part.

The theopy of drystone walling

Friday, 16 November 2018 11:32:59 Europe/London


We all need a hobby, a way to unwind. Some find the simple task of doing a jigsaw puzzle relaxing, others sitting in front of a warm fireplace and reading a book and some people have been taking up dry stonewalling. But what is it about the art of creating or maintaining a wall using natural stone and earth that some find so relaxing?


Drystone walling

Celebrity approved

If you have ever built a drystone wall I am sure you would have experienced that feeling of accomplishment; the moment when you step back and admire your work. Really, when you look at it, its not that far removed from the jigsaw puzzle I mentioned earlier. Each stone has a unique shape and somehow this all comes together to create a final picture. Even Pop Idol star Will Young has been using drystone walling as a therapy since suffering from anxiety and depression. I thought he was into Pop not Rock.

Just what the doctor ordered

However, all joking aside, it seems that more and more people are discovering the delights of drystone walling and its benefits to our mental well-being. Who knows, doctors may prescribe a healthy dose of walling in the future.
