At Virginia Drainage and Erosion, we design and install beautiful flagstone patios that bring a natural, rustic charm to your property. Each installation is tailored to fit your landscape and style, ensuring a seamless and elegant look that enhances your outdoor living space. Why Flagstone? Flagstone is one of the most beautiful and timeless patio materials available. Each piece is unique, giving your patio a one-of-a-kind appearance that manufactured materials simply cannot replicate. Natural flagstone — including bluestone, slate, limestone, and sandstone — is extremely durable, handles Northern Virginia's climate well, and actually improves in appearance as it weathers. Design Flexibility Flagstone can be installed in multiple ways depending on your aesthetic preferences and budget: - Dry-laid over compacted gravel — natural look, excellent drainage - Mortared on a concrete base — more formal, maximum stability - Random pattern — organic, natural feel - Cut pattern — clean lines, contemporary look Gaps between stones can be filled with ground cover plants, gravel, polymeric sand, or mortar depending on the look you want. Our Installation Process We assess your outdoor space, discuss your design preferences, source quality stone, prepare the base to ensure proper drainage and stability, and hand-set each piece to create a level, long-lasting surface. Flagstone installations done right require skill and experience — each stone must be set at the correct height and properly supported to prevent rocking or sinking.
