Flagstone building material
Flagstone is a thin stone that can be found as a man-made product or as a natural product in a quarry. The material is ideal for patios, as it is not only thin, but also very durable against damaging elements.
Flagstone can be used indoors and outdoors, and resists to different weather types.
Flagstone can be used to fill up cracks in the patio, as effective as sand, but offering a more natural look to the repaired area. The stone size is another advantage, especially when it comes to stone shifting.
Do some research on patio building materials and see what other materials can match flagstone. Each has its advantages and disadvantages. All you need to do is choose the one suitable for you.
