About Basalt

Basalt.jpg

Basalt is an extrusive volcanic rock that makes up most of the worlds oceanic crust. It is usually black to grey in colour and fine-grained due to rapid cooling of lava at the surface of the planet.

The crustal portions of the oceanic plates are composed predominantly of basalt, produced from upwelling mantles below the oceans ridges. Most basalt magmas have formed by decompression melting of the mantle.

Basalt is generally quarried in Asia where slabs of basalt are cut and polished and made into tiles, you would normally use basalt as a floor or wall tile where durability and strength are required.

An interesting fact about basalt; it has also formed on the Moon, Mars, Venus and even on asteroids.

About Granite

Granite tiles are formed from liquid magma pushed up toward the earth's surface to form a substance approaching the hardness and durability of diamond. Granite is an igneous rock; its chemical composition is similar to that of lava. However, granite owes its hardness and density to the fact that it has been solidified deep within the earth, under extreme pressure. Over the eons, seismic activity has changed the crust of the planet, forcing veins of granite to the surface. Granite tiles are renowned for their strength and depth of colour.


About Jura

Jura_1.jpg

Jura Marble or Jura Limestone are the trademarks of a beige, grey (grey-blue) limestone which is found in the Franconian region, just north of upper Bavaria in the south of Germany.

Jura limestone is a sedimentary stone and has a very fine graininess and contains many fossils and shell intrusions. Jura Limestone was formed approximately 175 million years ago. This time is described as the upper Malm, which is also described as the earth's middle age. Economically, it is the most important stone in Germany.

The quarries are approximately 50 meters deep and the layers of the Jura are up to 1.50 meter high, which also makes it possible to quarry this stone in blocks. The layers are divided from each other by thin clay layers. The layers are quarried by drilling and splitting machinery into suitable block sizes. We have to consider special geological circumstances like cleaves and cracks within the layers.

Windowsills, flooring and steps are all produced from Jura, and it is widely used in areas with high traffic because of its high durability and resistance to wear.

About Jerusalem stone

Jerusalem.jpg

Jerusalem stone is a name applied to various types of pale limestones common in and around Jerusalem, Israel that have been used in building since ancient times.

Various types of stone come from this area; a white, coarse crystalline limestone originally referred to as 'the stone of Kings'. A cream colored micritic limestone known locally as 'sweet rock', and a grey crystalline dolomite known as 'Jewish rock'.

These rock types were quarried from the Judean limestone around the Old City of Jerusalem. This variety of stone gives Jerusalem its unique character. The setting sun reflected on the cream-colored limestone facade of both ancient and modern structures gives them a golden hue, giving rise to the term 'Jerusalem of Gold'.

About Limestone

Limestone.jpg

Limestone is an organic, sedimentary rock. This means it was formed from the remains of tiny shells and micro-skeletons deposited on the sea bed. They were compressed to form solid rock. Limestone is formed in layers - called bedding planes. These bedding planes contain vertical cracks called joints. Joints and bedding planes make the rock permeable. Limestone tiles are usually light coloured however with impurities such as iron oxides and organic materials they can take on a variety of colours and surface markings. Limestone tiles have been used as a building material for many generations and is gaining popularity as a sophisticated flooring material offering the timeless qualities only possible with natural materials.

When selecting a limestone you must consider the application for which it is to be used to ensure its suitability. Choosing the correct material is always a balance between aesthetics and practicality and we are here to help and offer you advise. It's always worth looking at the technical specification particularly the porosity and always clarify the intended application of the material. We usually only offer the harder Limestone tiles as these offer easier maintenance and they have more advantages over Travertines as they do not have the natural holes and are generally far more durable.

The application is important when choosing a material for example, you could use a particular Limestone on a bathroom floor but would it be suitable for a busy family kitchen? We have a very experienced team who are happy to discuss your requirements and make recommendations based on the application.

Interesting fact: the Great Pyramids in Giza, Egypt, are made of limestone.

About Marble

Marble.jpg

Marble is a metamorphic rock resulting from the metamorphism of sedimentary carbonate rocks such as limestone or dolomite rock or metamorphism of older marbles. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite and dolomite crystals. The temperatures and pressures necessary to form marble usually destroy any fossils and sedimentary textures present in the original rock, resulting in a stronger harder material.

Pure white marble is the result of metamorphism of very pure limestones. The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, or iron oxides which were originally present as grains or layers in the limestone. Green coloration is often due to serpentine resulting from originally high magnesium limestone or dolostone with silica impurities. These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism process.

About Slate

Slate.jpg

Slate tiles are available in various colours and finishes that enhance the beauty of the floor. Attractive flooring schemes can be created using these beautiful natural stone colours.

The permanence of a slate makes it a cost effect option. A slate floor is durable, slip resistant and easily maintained. Its combination of hardness and beauty also make it a choice for commercial applications as well as the home. It can hold up to heavy and repeated traffic and still maintain its natural beauty.

Natural slate has a look that cannot be matched using man-made alternatives. Another dimension that can also be added is that of texture; slate is available in a naturally smooth finish or a rougher surface.
