    Can your stones be used to build water fountains and swimming pools?

    Royal Stone products are not recommended for use under a water line, or in a pool or water fountain. Owing to the large quantity of water and humidity, our product may deteriorate and become discoloured. We recommend the use of natural stone for these applications. However, normal exposure to water such as rain or snow will not alter the structure or colour of our product. It is designed for this type of installation and complies with masonry product standards.

    Of course. Use a diamond saw blade or a concrete blade. However, note that the colour will differ where the stone is cut. The aggregate will be visible, however mortar may be used to cover the cut area.

    One to two inches depending on the model and its texture.

    Do your products maintain their colour?

    The colour used in the production of our products is iron-oxide based and the main component used in colouring. Iron oxide has the same ageing properties as natural stone.
