Rock of the Week: Limestone


Limestone offers a versatile natural-stone solution that can be placed on walls, floors or outdoors. We think it’s a fabulously beautiful option for any home but there are a few things you must keep in mind before you select your stone.

A sedimentary rock, composed mainly of Calcite, limestone is formed through the crystallisation of water, or by the accumulation of shell fragments. This type of natural stone is normally light-coloured but impurities, such as iron oxides, can create a variety of colours.

There are so many variations of natural limestone that you should be careful when choosing your stone. First you must consider its application and choose the correct stone to suit your needs.

We tell our clients they should consider a stone’s technical specification, especially its porosity, and always explain where your chosen limestone will be used. Although price isn’t everything, it’s worth remembering the term ‘You get what you pay for’ when choosing your limestone.

In our opinion, the harder the limestone, the better. In terms of use and its competition, we always advise our clients to use limestone for flooring over other stones such as Travertine. This is because limestone has no natural voids within it and is extremely durable, so long as it has been treated properly.

Like slate, limestone colour and tones vary hugely. This is something worth keeping in mind if you’re hoping for a uniformed look. Remember that the limestone you order may vary from the sample you’ve received. That’s why we’re always happy for our customers to check their limestone before purchase.

Another factor worth remembering when choosing your limestone is quartz lines. Many people mistake these variations in the stone as cracks when in fact they can be the strongest part of the stone.

Limestone is one of our most popular stone choices when it comes to tiling options. It’s attractive, warm and brings a luxurious to any room. It’s a firm favourite of our residential clients but the last couple of years have seen a dramatic rise in the amount of Limestone used in offices and other commercial buildings.

Previously reserved for bathrooms and kitchens, Limestone has also seen a surge in its use within bedrooms and hallways in recent years. We’ve even had a number of people utilising this stone in their living rooms.

Limestone looks fantastic in a range of finishes, including polished, honed, brushed and sandblasted depending on the stone’s application and surrounding environment.

One thing you must remember is that all limestone requires sealing. As a moderately porous stone in the first place, it varies widely in porosity. Harder limestone, which is less porous, will still need treatment while soft limestones are virtual sponges in the world of stone.

We tend to avoid stocking soft limestone but if you have purchased this type of stone then be aware it needs professional sealing to prevent absorption and allow ease of maintenance.

All in all, limestone is another top-quality product which we love. There is nothing like a well-fitted limestone floor to keep you feeling warm and safe in the winter months but remaining cool in the summer. We think it’s brilliant!
