When choosing a hardscape for your Austin outdoor structure stone is a natural
Among the preference of materials used to construct our Austin area homeowners hardscape endeavors, the top choice is undoubtedly natural stone. Natural stone comes in a myriad of colors, textures and variances in undulation, or waves and bends present in natural stone. Natural stone is derived from a multitude of locations within our earth, and with any material that is derived from nature and the earth, no two pieces of stone are exactly alike. The differences and variations present in natural stone only add to its charm and part of what makes it so popular among the many materials available to create a truly unique hardscape outdoor structure.
Our signature item is the flagstone patio. Whether they are built-in unison with a decks, pergolas or one of the other stunning outdoor structures we build for homeowners here in the Austin area, the added essence of flagstone makes the entire project breathtaking. Austin is hill country which not only yields varying grades and steep drop offs which often includes natural stone, but natural stone used as a building material is common because of its natural beauty and the way it complements the natural surroundings and backdrops of Austin’s hill country. Flagstone is quarried from the ground and therefore will not yield a completely even surface. Flagstone patios are set on either concrete or mortar beds. The concrete base is referred to as a 1″ stone, and the mortar base is a 2″ stone. These terms are commonly used but the thickness of the stone itself can vary from 3/4″ to 3″. There can and will be movement on flagstone which is set on a base which is not concrete. Maintaining your flagstone patio, or other outdoor structure involves cleaning, sweeping or pressure washing on a low PSI and a fan tip is also recommended. Our flagstone patios our sealed with a “matte” finish penetrating sealer and are not visible to the naked eye that they are being absorbed. The seal will last from 6-12 months. After the initial sealing, the patio may be resealed again at your discretion. If you are placing a BBQ pit or grill atop your flagstone patio be careful not to let grease or drippings on the surface of the flagstone for they can stain the stone and become permanent.
Flagstone is not the only natural stone that is coveted among Austin homeowners for its beauty and unique characteristics. We also use sandstone in many of our projects. Sandstone is created when sand and an alkaline settling is formed under pressure and joined at the uppermost surface of the earth. Slate as well is a rich, deeply undulated natural stone that is popular in building outdoor hardscape structures. Slate and sandstone are very similar in the manner formation of the stone itself occurs. Slate is formed when wide ranges of minerals are compressed in layers near the earths’ surface over time. Slate is however prone to what is called “cleft plane spalling” which is a process where layers separate from the main stone body. Combined with the soft character of slate, these layers can be separated by walking on the surface, dropping or moving items over the surface or an excessive presence of moisture. Due to its’ soft nature, slate is also prone to scratching.
Running only second to flagstones popularity here in the Austin area is Leuders stone, also known as limestone. Limestone is formed when sea beds dry up in layers over time which results in the decay of aquatic organisms. This sedimentation process over time and intense pressure yields limestone. Limestone is basically calcium carbonate which is a pure form of a very soft alkali. Not unlike the other natural stones we have listed, limestone also can be stained or damaged by outside forces. When exposed to acidic properties which are present in wines, sodas, coffees and other beverages it can result in a condition referred to as an “etch mark” which needs to be polished to be removed. Repeated acid or high moisture attack can result in permanent and irreversible stone damage and color change. This stone class can scratch easily under normal wear. Despite the fragile nature limestone has under certain circumstances, it is one of the most beautiful stones we use and as long as it is properly sealed and taken care of can prove to provide years of outdoor enjoyment.
All of these types of stone are excellent choices for masonry projects. They can all be sealed to help prevent staining. These stone make ups are available in a chopped block, patio stone or cap stone. Combining various styles can add more texture and depth to a project. All are extremely durable and will outlast us all as we know since it has already existed for thousands of years. Within these stone types there are an extremely large number of colors and hues. So when choosing your hardscape material for your patio or other outdoor structure, natural stone is a natural indeed.
