Limestone is a form of sedimentary rock composed of a mixture of seashell, sand and types of organic matter. Every type of limestone in our product range has its own distinctive colours and markings and can differ notably in density. Some types of limestone look like marble and can often be mistaken for such. This mistake is often made because limestone becomes marble when it has been subjected to further geological conditions. As with most natural stones, some amount of edge chipping can occur as well as surface pitting. There can also be amounts of fossilised shells, striations (mainly caused by movement if ice when formed) and some amounts of resin filling. All these natural characteristics make stone unique. One should be aware that limestone is sensitive to products containing acid so care should be made when choosing sealing and cleaning products.

Originally the name “marble” was a term given by stone masons in the past. They applied this to any stone that had a polished finish. In reality, marble is derived from limestone that has gone through further processes in the earth such as additional minerals added and has been subjected to higher temperatures and pressure. A lot of marble is found where there has been a lot of old volcanic activity. These processes lead to a stone that has a dense closed surface but there may be some slight open veining or pitting in some minor cases. Marble has been used in buildings for thousands of years because of its plethora of beautiful shades and veining. There are some marble types that have such prominent veining that tiles formed by them often are reinforced with mesh to hold it during transport and cutting. Marble comes both in a polished and tumbled finish.


Travertine is a sedimentary rock formed similar to limestone. The main difference is during its formation hot mineral spring water has filtered through the stone causing holes and voids. Travertine is very distinctive because of these holes & voids and can be left open or filled with a compatible coloured resin (or grout). They also come in two kinds of cut, vein cut or cross cut, vein cut is when the stone is cut along the vein planes and cross cut is when it is cut across the vein. This is less common with tumbled, brushed or split face finishes where they tend to get filled during the grouting process. Filling gives a much smoother surface to the stone but be aware that during usage and over time small areas the fill may become loose. This is normal and can easily be refilled with the correct grout or resin. Because of the nature of large voids on the back of the tile additional adhesive may be required on some types of travertine.

SLATE. Read More

Slate is one of the finest fine-grained foliated metamorphic rocks, known for its durability and weather resistant(reason why it was used in roofing). Slate is easily split into smooth, flat plates and as tiles come in a calibrated or un-calibrated state. Un-calibrated means batches come with varying thickness of tile. Calibrated means that they have a set thickness across all tiles in a batch. Un-calibrated tiles require sorting before laying, generally thicker tiles are laid first as you can always raise thinner tiles with more adhesive. Slate can be used internally or externally.


These are densely crystalline, metamorphic rocks that offer considerable shade variation, ranging from light cream/white to charcoal grey/black with many colours in between and often contain reflective crystals which glisten in the light. Highly textured Splitface panels are available in both Schist and Quartzite.

GRANITE. Read More

Granite is a hard, crystalline, igneous rock formed from molten magma that has cooled way down below the earth’s surface. Granite is one of the hardest stones you can get (probably why they were used for grinding wheels in the old days) and come in a flamed, polished and honed surfaces. A flamed finish is ideal for external applications. Granite contains a numerous array of mineral crystals some that may be sensitive to acid so it is important to ensure that the correct sealers and cleaners are used.


Sand is the most common material on the earth’s surface so it’s not surprising that sandstone is formed from this. Sand contains quartz and feldspar and along with some minor minerals, when it is compressed it creates this well-known stone. Our sandstone tiles and pavers come in honed or natural split finishes. A honed finish will give you smooth finish, whilst a natural split will give you an abrasive finish. It is important to know that sandstone is hard, yet is very porous which means it needs suitable penetrating sealants to ensure that the beauty of this classic stone is maintained.
