Natural Stones Vs Concrete
Concrete Pavers are made from a very dry mix of aggregate, sand, cement , pigments and dyes. Manufacturing processes can vary slightly, generally however very little water is used and the mixture is funnelled into a paver mould. The mould is then pressed and vibrated at the same time, causing the water to set the cement and bind the aggregate. Some manufacturers fire the concrete pavers in large industrial kilns.
In this respect concrete pavers are similar to brick pavers in that they are made of a mixture of raw materials, set in a mold and fired or dried at the manufacturing plant. Like brick pavers the end product is strong and usually suitable for driveway and even road use.
Due to the use of dyes and pigments, concrete pavers offer a broader range of colours, than what is available with brick pavers. Depending upon the manufacturing process the colour of concrete pavers can remain the same for many years, however may not maintain their colour as well as brick pavers. The use of sealants will help concrete pavers maintain their colour for longer.
Concrete pavers generally cost less than brick and natural stone pavers because their raw materials cost less to produce.
Natural Stone Pavers
Stone pavers is a general term used to describe a broad range of natural stone pavers. The stone pavers are usually mined or collected from a quarry or rock outcrop and sometimes cut and assembled for sale as a paver. Stone pavers don’t involve the manufacturing processes typically used for concrete and brick pavers where the paver is made of a combination of materials being mixed, pressed and fired.
There are many different types of stone pavers that are available including Granite, Limestone, Marble, Porphyry, Flagstone, Sandstone, Bluestone and Slate. Each which has it own unique properties that will make some of them suitable for particular applications and not others. For example granite pavers are very strong and would be suitable for driveways, while marble would not.
Because of their origin, they look very natural and appealing, however due to the mining process they are considerably more expensive than brick or concrete pavers. They are also more time consuming to install because they may lack uniformity in size. They are generally better suited to walkways and paths rather than vehicle areas. Careful research is required when choosing stone pavers for your landscaping projects.
