What really goes into building a flagstone patio?
Patios are very popular here in the Austin area and flagstone patios in particular are one of the most requested type of patios among our customers. The rustic elegance they provide compliments our Texas landscape and unique home designs. Installing a flagstone patio requires a lot more steps than it may seem.
The first steps begin once the dimensions are determined during our pre-construction meeting with the homeowners. Following this important meeting we then have the concrete poured to form up the shape of the patio. Sometimes the homeowner first needs to contact their sprinkler system company and have them re-locate any sprinkler heads that are in the area of the intended patio, if not Archadeck of Austin will cap off the heads. If we are building a “full-on” patio next to a house that is built on a slab our professional concrete contractor will also install rebar every two feet to connect the foundation of the patio to the foundation of the house. This extra step ensures a stable patio foundation. Once this step is completed we then pour the perimeter of the patio. We pour this 1ft. by 1ft. around what will become the perimeter footing, we also add rebar to this area as well for an added measure of strength. Most other companies just don’t take this step; we however feel it very important for the strength and life of your patio.
Depending on the slope of your yard, we may install a fascia. A fascia involves the underpinning which is concrete paint that is trimmed so it doesn’t convey a rough vertical surface. We will then use vertical stones around your step areas. Typically this is not done around the entire perimeter because over time it can flake and break off so we do something that will last over a long period of time.
On the top of the poured patio base we add a 4″ deep cap and pour an additional 4″ of concrete strengthened with wire mesh. Depending on the size of your patio, we may also install man-made, control and expansion joints every 10-12′ depending on the width. Once those layers of concrete properly cure, the flagstone will then be delivered by the stone company so our expert masons can lay out the flagstone in a mosaic pattern. Once they are laid out and everything is concise, we then put in the mortar that was chosen by the homeowner. One thing we are proud of is the tight mortar joints we do so well, this gives you a flagstone patio that looks like stone when you look at and not all mortar. After all, our customers are paying for stone, not mortar. After the mortar is done, the next step is to apply a sealer. The sealer is undetectable to the appearance of the patio, but it keeps moisture from penetrating the stone and also keeps mold and mildew out. The sealer also gives the finished patio a cleaner look. After applying the sealer you shouldn’t have to do any further maintenance for 5-10 years.

When the stone selections are made we generally meet our customer at the stone shop to help them with their selection and any questions or concerns they may have about a particular stone. There are actually 10-14 various types of flagstone to choose from. The most popular flagstone choices are Oklahoma, Arizona and Mexico. All the most widely used flagstones come from Oklahoma. Sometimes when we use flagstone we will incorporate beautiful and useful features such as stone benches or even a stone kitchen island if your patio incorporates an outdoor kitchen.
Flagstone patios are not only gorgeous, they are a solid material choice for your patio because with a stained concrete or concrete patio when it cracks, and it is not a question of if it cracks, but a question of when, you will have to live with it. When you use flagstone and the concrete underneath cracks you may get a little separation of mortar joints over time but you won’t see a line in the stone. Making sure your flagstone is installed by a licensed professional ensures the beauty and enjoyment of your patio is treasured for many years to come.

A Round Rock, TX transformation nestled among the beauty of the trees.
These Round Rock, TX homeowners have one of the most beautifully lush backyards. Being able to incorporate an outdoor living structures within this backyard could seem like a challenge to some, but not to us. The mingling of the wood and flagstone we used to create this outdoor retreat is mesmerizing set against the beauty of the rush of green in this residence.
These homeowners had an existing concrete patio that was not serving their needs. Our goal was to extend the patio and pour a whole new facet of enjoyment into their backyard. Our design included a covered patio extension complete with an outdoor kitchen and pergola-style roof and another patio that descends from the covered patio to the new outdoor fireplace.
In designing the master plan to transform this Round Rock, TX backyard into a paradise for the senses we first had to overcome some obstacles. The first challenge was to incorporate all the desired structures into the homeowners minimal backyard and also deal with the small elevated back porch. The design we decided upon that would work best was to actually create two structures out of one area by extending the small space to make it larger and adding another space to serve as the focal point for the outdoor fireplace.
We designed an extension of the existing concrete patio and added stone over the top of the concrete for seamless design. We then added the pergola with an extension as well over the patio and added a little slope to compensate for the existing patio being so high. The small round patio located in the design accents the large outdoor fireplace located at the corner. We used a round design for the patio and continued the curved design feature into the fireplace’s eyebrow and hearth.
The medium we chose to cover the patios with is gorgeous Oklahoma flagstone in buff peach. We also used block stone in the design using Autumn blend block stone. The element of the two separate stones working together along with the cedar pergola and the trees on the property is truly breathtaking.

Archadeck of Austin custom designed this cedar cabinet located above the mantel of this outdoor fireplace to safely and efficiently house a TV.
The outdoor kitchen is located inside the patio cover and includes a grill, refrigerator and plenty of electrical outlets. The countertops are finished out with a very nice tile that compliments the homes brick colors. The rustic outdoor fireplace is graciously equipped with custom cedar cabinets above the firebox made especially for housing a television and keeping it safe and dry from the elements.
These Round Rock, TX homeowners couldn’t be more thrilled with the transformation, they say it feels as though they have a whole new backyard. We can create a stunning transformation of your back yard as well, contact Archadeck of Austin to learn more (512) 259 – 8282

Oklahoma flagstone patios in Austin TX
If you live in the Austin area, you’ll see flagstone patios everywhere. They’re tremendously popular in this area for several reasons. First, they’re very attractive and have a very natural look which compliments that Austin landscape. The stone has a nice rustic feel and also adds subtle depth and texture to your patio.
Cement patios are also very popular right now with stain & stamp and stain & score. All of these concrete styles are very nice but just have a different feel. The feel of the stained concrete will depend largely on the stain color. Darker colors may often look more formal. There are hundreds of patterns and textures you can achieve with stain and stamp. In this scenario, the concrete is stamped to add a pattern that’s either just attractive to look at or a pattern designed to mimic a more natural look – perhaps the look of natural stone.
When looking at flagstone, it’s a great way to finish an existing cement patio or a great finish for a new patio you’re building. With our Archadeck customers, it’s always a popular request. We mainly work with flagstone from Oklahoma, Arizona and Mexico. The Oklahoma Buff Peach is one of our favorite flagstones to work with. The flagstone surface tends to be a smoother and flatter finish than some of the other Oklahomas – not as much undulation. The colors tend to blend with pretty much anything. The top surface tends to also be more consistent. This is important when looking at flagstone. Some of the other colors or varieties can have a more undulating surface which looks beautiful and natural but can be tougher to put your furniture on. Of, if you use it for the top of your bar, it may be tougher to place table settings on.
Some of the other Oklahoma flagstone colors we work with are Arizona Taupe which is similar to Oklahoma Buff Peach but is a little more subtle with all the shades leaning more toward the taupe hues. We also work with Oklahoma Silver Mist flagstone. It also is more subtle because the hues of the various stones all lean more toward gray. But in both the Oklahoma Silver Mist and Oklahoma taupe, you still have that nice unique variety of colors that complement each other and make your patio interesting and one-of-a-kind.
Your one-of-a-kind patio
We like to think that all of our project are one-of-a-kind from a design perspective. And, in reality they are. We never use the same project design twice. Every single customer gets their own rendering, their own architectural plans, and more. Every back yard is different and every family is different in terms of how they want to live in their back yard. What’s nice about flagstone is that every patio is one-of-a-kind. Flagstone is 100% natural and cut from the earth. It is not manufactured so no two stones are completely alike. So not only will the design of your project be one-of-a-kind, but your patio colors and stones are also.
The many colors of Oklahoma Buff Peach
Oklahoma Buff Peach is tremendously popular as I said above. We probably use this more than the other colors. The colors in this group are very subtle and pleasing but they also have enough variety to be interesting and unique. The hues include subtle peach tones, subtle taupe tones and even some subtle gray tones. Here are some pictures from our actual patios to show you the interesting color variations of the natural stone.
Perhaps it’s because this patio above adjoins a richly colored Tigerwood deck, the variation from this stone lot looks more subtle than the next two pictures.
This patio above uses the same flagstone color and you can see a more chocolate shade and darker taupes in addition to a lighter, whiter shade.
In this picture above, there are a bunch of more shades toward the taupe end of the spectrum as well as some darker peach hues.
Here’s another Oklahoma Chocolate Gold patio that’s screened in with some detail about flagstone finishes.

Flagstone Patios in Austin
Guest post by Wes Vann
We build a lot of flagstone patios. I think they’re popular because they have such a nice, natural rustic look, but they’re a hearty stone and stand the test of time. We work with a lot of colors but recently one of the colors that a lot of customers seem to gravitate to is Oklahoma Buff Peach. Flagstone is a naturally occurring stone so that adds to the natural feel. The naming of the colors represents two things. First, you will note that state name in the color. That really does indicate where it is sourced from. The rest of the color name represents the overall color impression and the variety. For example, Oklahoma buff peach is subtle with a lot of buff and taupe tones. On the other side of the range is a mild peach tone. You can imagine that the shades in between make for a very subtle combination.
Another really hot one right now is Oklahoma Chocolate Gold. This brings to mind very rich variations of stone color from a deep brown to the golden warm colors. The shade shown on the right above is the chocolate gold. You’re seeing a close-up there so here is a look from a little bit farther away so you can see how the color combination blends from chocolate to gold.
Here are some other popular colors right now:
- Oklahoma Taupe flagstone
- Arizona Buckskin Beige
- Arizona Classic Oak
- Arizona Rosa
- Mexican Rosewood
- Mexican Cafe
- Mexican Midnight Iris
Please send along questions or comments or thoughts. I love working with flagstone and love talking about ideas for building using flagstone.
