Timeless Beauty, Natural Durability—Built to Fit Your Central Texas Landscape
If you’re looking to enhance your outdoor space with something durable, classic, and easy to maintain, flagstone is one of the best choices you can make. At AC Cornerstone Building, we design and install custom flagstone pathways and patios in Austin, TX, with a focus on craftsmanship, long-term performance, and a natural look that fits right into the Central Texas landscape.
Whether you’re dreaming of a winding garden path or a spacious stone patio for entertaining, we’ll help you bring it to life—on time and built to last.
Flagstone is a go-to choice for Austin homeowners because it blends rugged durability with timeless style. Each stone has its own texture, tone, and shape, creating a look that’s organic and one-of-a-kind—perfect for everything from Hill Country homes to modern backyard escapes.
Here’s why flagstone stands out:
✅ Long-Lasting: Flagstone resists cracking and holds up to high foot traffic and Texas heat.
✅ Low Maintenance: Just sweep or hose it off—no staining or sealing required for most installations.
✅ Non-Slip Surface: Naturally textured for safer walking, even when wet.
✅ Natural Drainage: Dry-laid installations allow water to pass through gaps, helping with runoff.
✅ Custom Look: Each installation is unique, with options to match your home’s color and style.
Whether you’re tackling a small garden walkway or building a full outdoor living area, flagstone is a material that delivers both form and function.
Not all flagstone is the same—and that’s a good thing. We help you select the right type of stone and layout to match your vision, your home’s architecture, and how you use your outdoor space.
Limestone: Light-colored, common in Texas, and easy to shape—great for patios and pool decks.
Sandstone: Earthy tones with excellent grip and texture.
Quartzite: Dense and durable with subtle sparkle and cool color options.
Irregular (Natural Fit): Uneven shapes pieced together for a rustic, organic look.
Cut/Patterned: Square or rectangular stones set in repeating patterns for a cleaner, more modern appearance.
Stepping Stones: Spaced-out stones in gravel or grass—perfect for pathways.
Dry-Laid vs. Mortar-Set: We’ll help you choose the right installation method based on drainage, soil, and style preferences.
At AC Cornerstone Building, we’ve built our reputation on clear communication and quality over quantity. You’ll never be rushed or left wondering where your project stands.
