Limestone is a strong and durable material ideal for many building projects such as cladding, feature walls, retaining walls and much more. There is natural limestone or reconstituted limestone, which is basically crushed limestone mixed with cement. This makes it even stronger and adds to its versatility. So which should you choose for your walls?
Much depends on the position of the walls, your budget and your colour preference: –
Position – walls that are in very exposed places where wind and rain can beat on them all the time need to be stronger than a wall in a sheltered spot. Limestone is slightly softer than some other stone types. Even though it is considered quite strong enough for walls, some slight erosion may occur over the years, making sharp edges more rounded. So if this is important to you, natural limestone may not be the best choice for such a wall. However, if the position is sheltered from wind and seawater spray, natural limestone could be a good choice.
A feature wall on the sheltered side of the house would be fine with natural limestone; similarly, cladding on the house itself would be suited to natural limestone because the inner side would be totally out of the weather.
Reconstituted limestone blocks will give you a wall that is both attractive and durable, standing the test of time in the weather due to its cement component. It would be fine for garden walls, retaining walls, cladding or even feature walls.
