This rustic entranceway was built to open up the front of our clients home. The flagstone is a Permacon product that actually comes in one shape. Different grooves in the surface of the slab give the appearance of natural varied flagstone. One benefit of having a slab that imitates the look of a natural stone rather than natural stone itself, is the consistency of the product. This slab is quality tested with a uniform surface that eliminates the variance in height (and therefore eliminates tripping hazards). It is also backed by the company's warranty and is de-icing salt resistant.
