Marble Slabs in the GTA

When searching for what constitutes a quality marble slab in the GTA, what are the factors to consider and the applications that it can be used for?  What indeed constitutes the measurements of a slab?  The following will address these questions and further examine the nature of marble and why it is a popular choice in comparison to other stone-based materials.

Where Does Marble Slab Start? How is it Produced?

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. This metamorphism comes from sedimentary carbonate rocks that are most commonly limestone or dolomite.  Much like granite, marble, is a very popular material in modern construction and is used for both interior and exterior purposes due to its attractive composition and complexion.  It is also extremely popular for sculpture.  A slab is usually referred to as material that has been cut from mined rock and roughly measures between three quarters of an inch thickness to one and a half inch thick.  The reason for cutting marble into slabs is to make the material both easier to work with and transport.  On average, the length and width of marble slabs are around 112 inches long and 65 inches wide.  These slabs can weigh up to 12.8 lbs per square foot for three quarters of an inch thickness and up to 18 lbs per square foot for the thicker one and a half inch slab.  It is important to remember that because of the size and weight of these slabs of marble, there is a high risk of injury involved with them and only professional fabricators should handle or cut them.

Maintenance and Applications for Marble Slabs

The main applications for marble slabs in the GTA are usually for residential and commercial construction purposes and are commonly used in areas such as bathroom design, sculpture or monuments.  The physical appearance of marble is generally a solid grey-white or cream colour with dark veins running through it.  These veins in marble are formed due to mineral impurities such as silt and iron oxides.  Its complexion is generally a dull smoothness but it can be polished using sealants to make a glossier appearance.  Marble can create a light and unique appearance for surfaces so it is popular for vanities, tub decks, shower walls, and flooring.  Marble is a porous material and therefore requires sealants to protect it against staining or scratching, depending on damage or usage it may need to be sealed twice a year.
