When it comes to choosing stone, you have a lot of choice. There are many beautiful types of stone for you to choose from and it’s important to understand a stone’s basic properties before you can make an educated decision as to which stone will work best for your next project. The right stone for one project may not be the right stone for another as both appearance and performance need to be taken into consideration.
Please be aware that not all stones are the same. To properly maintain the beauty and character of natural stone, you first need to understand how it was created. Some stones are soft and stain easily, some are very hard and dense. The amount of silica in the stone is a major factor which determines the porosity of a piece of stone. High silica means low porosity, good stain and chemical resistance. Low silica means high porosity, poor stain and chemical resistance.
Limestone, Travertine and Sandstone contain low levels of silicates. They are all examples of sedimentary stone which is porous. Therefore, these stones are best located in low traffic areas and will need to be sealed and then maintained with a ph neutral, or slightly alkaline cleaner.
Marble and Slate are metamorphic rocks and contain relatively low levels of silicates. They are more stable and less reactive than sedimentary however they will still require some degree of maintenance. Marble is best avoided on kitchen bench tops where acids such as vinegar and lemon juice can affect the surface.
Granite and Basalt, both igneous rocks, contain high levels of silicates and are very stable and non-reactive and can therefore be located just about anywhere. However basalt contains calcium which will react with acid so its use is not as universal as granite.
Natural stones are a product of natural and therefore variations in the colour and veining of natural stone is to be expected. STS Stone is not liable for any such variations that occur in materials supplied. Being a natural product there could be minor variations in dimensions and thickness.
We have a vigorous quality control system and we take great care in checking prior to the stones leaving the quarry, however the homeowner, builder or tiler must inspect the tiles prior to laying, to check for defects, that the tiles delivered are of correct quantity, shade, colour and size as ordered. You will also need to check that the shade of tiles delivered is consistent throughout the batch. It is up to you to ensure you order enough of the same tile from the batch prior to work commencing.
We suggest that you order the industry standard of 10% extra to allow for wastage and cutting on site and spares.
We strongly recommend that you only chose experienced tilers/stonemasons to lay your natural stone in order to prevent damage to the material.
We recommend you test the material for suitability of application.
Pre sealing of sandstone and limestone is recommended prior to installation around a salt water pool.
Drainage: All paving should incorporate good drainage and that the bedding sand can drain freely. For sand bedding over concrete, if not drained correctly if course sand is bedded over concrete the sand will become saturated and the pumping action caused by traffic will expose the pavers to waterbourne staining. For more information on drainage for your specific job consult your tradesman or call our office to discuss this in more detail.
Edge Restraints: Depending on the method of laying, the type of edge restraint will vary. For more information on edge restraints consult your tradesman or call our office.
Measuring: A simple way to measure a project is to divide it into a series of squares or rectangles. Multiply the length times the width with give you the area. For triangular areas measure and multiply the two sides at 90 degrees to each other and divide them by two.
