Glossary of Terms

Material Types


Slate is a fine-grained metamorphic rock, made up of many layers under relatively low pressure and temperature. Slate tiles typically have a naturally riven surface that gives a rustic finish. Due to the layers of the slate, there may be some very slight layers on the surface of the tiles giving a subtle texture.


Sandstone is a sedimentary rock formed of coarse grains of sand and minerals which have been compressed. Sandstone tiles come in large format, flagstone tiles which are suitable for internal and external use. They are available in a riven finish characterised by a granular, undulating surface which gives a textured and rustic finish.


Limestone is a sedimentary rock formed from different crystal forms of calcium carbonate. Most limestone contains fragments of marine organisms, seashells and sediment, which have been compressed to form solid rock. There are many types of limestone, with quite different characteristics, colours and markings and it is not uncommon to see fossilised shells or veining and fissures in the surface markings.



Natural Stone paving, large format, often random in length and width.


A flat rectangular piece of natural stone or concrete used as a paving material.


Mainly referred for use as interior flooring or walling applications. Generally, thinner than flags or slabs albeit on occasion interchangeable depending on application and environment.


Dimensional/rectangular/cubic stone or concrete used for external paving, driveways or pathways. Minimum 30mm thickness.


Dimensional stone, concrete or clay used on driveways and pathways as a finished surface.


Aggregates refer to coarse to medium grained particulate material used in construction, that includes sand, gravel and crushed stone, and in a domestic project for use in the gardens, driveways and pathways for decorative and maintenance purposes.


Small-sized crushed and graded stone typically larger than 10mm


Sometimes referred to as Aggregate or Mulch, or vice-versa, and can be a mixture of different size pieces of stone or slate.


A covering placed around plants (or covering the ground in lieu of plants), mainly to prevent the growth of weeds. Use of stone mulch is an excellent alternative to typical wood varieties of mulch.


The amount of material required to cover a given area to a given depth.


A small piece of stone intended purely as a guide and unfortunately cannot how all possible tonal and texture variations of the natural stone.
