Driveway & Road Construction
Rural properties throughout Central Virginia depend on well-built driveways and private roads for reliable access year-round. Thomasson Septic & Excavating constructs new gravel driveways, regrades deteriorating drives, builds private roads, and installs culverts — all with proper drainage to prevent the washouts and erosion common on the hilly Piedmont terrain.
Gravel Driveway Construction
A properly built gravel driveway starts with the base, not the surface. We excavate the driveway corridor to the required depth, install geotextile fabric when soil conditions warrant it, build up the base with compacted crusher run or road base material, and finish with the surface gravel of your choice. Every driveway is crowned or sloped to shed water and prevent the rutting, potholes, and washouts that plague poorly constructed drives.
- ✓Full excavation and base preparation for long-lasting performance
- ✓Compacted crusher run or road base stone for structural stability
- ✓Surface gravel selection — #21A, #57 stone, or other materials
- ✓Crown or cross-slope grading for positive water drainage
- ✓Edge definition and shoulder grading to contain gravel
Driveway Regrading & Repair
Existing gravel driveways deteriorate over time — potholes develop, gravel migrates to the edges, ruts form in wheel paths, and drainage features fail. We regrade existing driveways to restore proper shape and drainage, add fresh material where needed, and address the underlying causes of deterioration. If your driveway has chronic problems like recurring washouts or soft spots, we diagnose the root cause rather than just adding more gravel on top.
Culvert Installation
Many rural driveways cross drainage ditches, creeks, or low areas where water flows during rain. Culvert pipes allow water to pass under the driveway without washing out the surface. We install culverts of the appropriate size and material for your site, set at the correct grade for water flow, and properly backfilled and compacted to support vehicle traffic. Failed or undersized culverts are a common cause of driveway washouts — we can replace them with correctly sized pipes.
- ✓New culvert installation for driveway stream crossings and ditch crossings
- ✓Replacement of failed, crushed, or undersized culverts
- ✓Proper headwall and endwall construction to prevent erosion
- ✓Sizing culverts to handle expected water flow and prevent backup
Private Roads & Access Roads
Private roads serving multiple properties, farm roads, timber access roads, and long driveways to remote building sites all require proper construction to withstand regular traffic and weather. We build private roads with appropriate base depth, surface material, drainage, and width for the intended use. For roads that will serve multiple homes, we ensure the construction meets any HOA or county standards for private road construction.
We also build turnaround areas, parking pads, and equipment staging areas — common needs on rural properties where fire department access turnarounds may be required by code.
- ✓Private roads for multi-lot properties and subdivisions
- ✓Farm and agricultural access roads
- ✓Turnaround areas for fire department access requirements
- ✓Parking pads and equipment staging areas
- ✓Base preparation for future paving or asphalt

Frequently Asked Questions
How thick should a gravel driveway base be?
A properly constructed gravel driveway typically has 6 to 8 inches of compacted base material (crusher run or road base stone) topped with 2 to 3 inches of surface gravel. The exact depth depends on soil conditions and expected traffic loads — heavier vehicles or soft soils require a thicker base. We evaluate your specific conditions and build accordingly.
Why does my gravel driveway keep washing out?
Driveway washouts are usually caused by one or more of these issues: lack of proper crown or cross-slope (water runs down the driveway instead of off it), missing or undersized culverts at drainage crossings, insufficient base material allowing the surface to rut and channel water, or steep grades without water diversion features. We address the root cause, not just the symptom.
What type of gravel is best for driveways?
We typically use #21A (a crushed stone and dust mix) or crusher run for driveway surfaces — these materials compact well and create a smooth, stable driving surface. Round river gravel looks nice but migrates and creates ruts. For the base layer, we use a larger crusher run that provides structural support. We recommend materials based on your specific use and preferences.
Can you prepare a base for a paved driveway?
Yes. We excavate and grade the driveway corridor, install the compacted stone base to the specifications required by your paving contractor, and ensure drainage is properly established. A well-prepared base is critical to asphalt or concrete longevity — we work with your paver to meet their exact requirements.
How long does a new driveway take to build?
Most residential driveways take 1 to 3 days from excavation through final grading, depending on length, terrain, and whether culverts or other drainage features are needed. Longer driveways on steep terrain or those requiring significant tree clearing take more time. We provide a clear timeline during our free estimate.
