Estate Transformation: Solving Complex Drainage with Luxury Driveways & Stone | Northern Virginia

This Fairfax, VA estate had a ruined, half-gravel asphalt driveway and a front yard sloping heavily toward the house and driveway. We replaced the driveway with an engineered concrete system, starting at the street with a custom concrete apron built around the existing drainage culvert, and wrapped the entire parking area in a Techo-Bloc Linea paver border. A driveway and apron this size sheds a lot of water, so we installed river rock edging and drainage beds around the lower apron.

Getting the water away from the house

We built a structural retaining and seating wall wrapping the project. Hidden directly behind it is a high-capacity French drain, topped with river rock, that catches hillside runoff, ties into every downspout and carries water out to the street. Roof runoff is one of the biggest sources of yard saturation, so we hard-pipe downspouts into the system using solid, non-perforated pipe. The home's original front porch deck had been built below grade, leaving the wood steps sitting in the dirt, so we excavated the front yard down over 12 inches to correct the grading, which opened room for a two-tiered flagstone patio in place of a failing 10x10 dry-set sand patio. The patio is Pennsylvania natural cleft flagstone in a pattern 2 layout, every wall is capped with 2-inch premium thermal blue Pennsylvania flagstone, and Pennsylvania blend river rock runs around the whole project.

The garage foundation

During the driveway excavation we uncovered a structural flaw: the garage foundation did not line up with the house, and its load-bearing corners were failing. Rather than cover it up, we halted the hardscape, brought in a dedicated masonry trade crew, rebuilt the garage foundation corners to carry the new load, precision-cut the old concrete so the new pavers tuck cleanly under the garage doors, and wrapped the repaired foundation in stone veneer. The apron and culvert work sit in the VDOT right-of-way, so that part of the job ran under a VDOT land use permit.
