The Science of
Virginia Clay
Richmond's Piedmont clay is notoriously unstable. We don't just "lay pavers"—we engineer structural foundations that defy soil movement.

"Most hardscape failures in Central Virginia aren't caused by the pavers—they're caused by the reactive subgrade. Standard 4-inch bases are essentially floating on a slow-motion liquid. We dig deeper to find stability."
Why Richmond Clay Destroys Patios
The Greater Richmond area sits on Ultisols, ancient Piedmont clays that act more like a hydraulic fluid than solid ground. Under a microscope, clay particles are flat plates. When water enters, these plates slide and expand, increasing volume by up to 15%.
The Shrink-Swell Cycle
Wet winters cause the soil to "heave" upward. Dry Virginia summers cause it to shrink and crack. This cycle snaps concrete and shifts pavers that haven't been properly stabilized.
Subgrade Pumping
Without a separation layer, traffic over the pavers forces wet clay up into the gravel base. This "pumping" destroys the base's load-bearing capacity and drainage.
The Evergreen Stabilization Method
We utilize a "Floating Slab" methodology inspired by heavy civil engineering. Our installations don't fight the clay; they bridge it.
1. Multi-Dimensional Excavation
We excavate 10-14 inches deep. This removes the "O-Horizon" (organic layer) and the most reactive upper clay layers. We create a smooth, pitched subgrade that allows water to move to a designated discharge point rather than pooling under your stone.
2. Non-Woven Geotextile Armor
We line the entire excavation with 6oz non-woven geotextile fabric. This is your insurance policy. It prevents the subgrade from ever contaminating your aggregate base, ensuring the drainage remains clear for decades.
Aperture Confinement & Geogrids
For driveways and large patios, we integrate Biaxial Geogrids. This high-tensile mesh locks the aggregate in place. Instead of stones shifting individually, they lock into the grid's "apertures," creating a rigid, reinforced platform that distributes point loads across thousands of square inches.

- ✓ Bridge Soft Soil Pockets
- ✓ Civil Engineering Grade
3. Aggregate Interlock
We don't use "crusher run." We use clean, angular #57 and #8 stone in managed lifts. The angular edges of the stone provide mechanical interlock—the stones literally bite into each other. When compacted, this creates a stable matrix that allows water to flow through while resisting any lateral movement.

Protect Your Investment
Hardscaping is a major investment in your home's equity. In Richmond, Virginia, you cannot afford to ignore the soil. A beautiful patio built on a weak base is just a pile of expensive trash waiting for the next rainy season.
