What Lilburn GA Homeowners Need to Know About Paver Driveway Installation

Lilburn is one of central Gwinnett County's most active residential markets — a community with a long history and a real estate landscape that includes everything from established ranch homes built in the 1970s and 1980s to newer construction in planned subdivisions off Ronald Reagan Parkway and US-29. Across this range of properties, driveway replacement is among the most impactful exterior upgrades available — and paver driveways specifically represent a step change in quality, durability, and curb appeal that concrete and asphalt alternatives cannot match over a meaningful time horizon.

The driveway is often the first exterior investment a new Lilburn homeowner makes, and the last one they want to make twice. Understanding what a proper paver driveway installation requires — the subgrade work, the base depth, the material specification for vehicular applications, the edge restraint at the curb cut — is the starting point for evaluating any contractor proposal and for understanding why bids vary significantly across the market.

Installation Requirements

Subgrade Requirements and Heavy Vehicle Load Planning

A paver driveway carries loads that a patio does not. A standard passenger vehicle weighs 3,000 to 4,500 pounds. Full-size trucks and SUVs — common in Lilburn's suburban market — reach 5,500 to 8,000 pounds. This load is distributed across four tire contact patches, but the concentrated pressure at each patch, multiplied by thousands of loading cycles per year, requires a base system engineered for vehicular application. The minimum base depth for a residential paver driveway is 8 to 10 inches of compacted aggregate — significantly more than the 6 inches used for pedestrian patios. Shortcuts here are not visible at installation and become very visible at year four when the surface begins rocking and heaving under repeated load.

Paver thickness specification is equally critical and equally skipped by contractors who do not specialize in driveways. Pedestrian pavers are typically 60mm (2.36 inches) thick. Vehicular pavers must be at least 80mm (3.15 inches) thick to distribute load adequately across the aggregate base. A contractor who installs 60mm pavers on a driveway is installing the wrong product for the application — the pavers will crack at point loads over time, and the installation will fail ahead of schedule.

Edge Restraint, Joint Sand, and the Curb Cut Challenge

Edge restraints hold the perimeter pavers in position against the lateral forces that vehicle loading creates. Without properly anchored edge restraints — pinned into the subgrade with spikes at regular intervals — the driveway apron will spread at the edges over time, opening gaps between pavers and allowing the bedding layer to migrate. For Lilburn driveways, the most critical edge restraint location is the curb cut — the transition from the street to the driveway. The height differential here is small but the load concentration is high, and the edge restraint must be installed correctly and pinned adequately to resist the repeated load of vehicle entry and exit.

Joint sand is the final variable where residential driveway installations are frequently compromised. Standard joint sand — plain washed concrete sand — washes out of driveway joints within the first rainy season. Without joint sand, individual pavers lose lateral restraint and begin to rock. Polymeric sand, which cures into a semi-rigid compound that resists washout and resists weed germination, is the only appropriate joint sand for a driveway application. It costs slightly more at installation and eliminates the ongoing joint sand replacement cycle that standard sand creates.

• Base depth: 8–10" compacted aggregate minimum for vehicular applications
• Paver thickness: 80mm minimum — 60mm pedestrian pavers are not adequate for driveways
• Edge restraint: pinned every 12" along all free edges, especially at curb cut transition
• Joint sand: polymeric sand only — standard concrete sand washes out under vehicle loading
• Curb cut transition: height and slope must comply with local municipality standards

Evaluating Competing Bids for a Lilburn Driveway Project

When comparing driveway bids in Lilburn's Gwinnett County market, the most useful evaluation tool is a written scope of work that specifies every installation component. Ask each contractor to provide the following in writing before you compare prices: base depth in inches, paver thickness in millimeters, edge restraint product and pin spacing, joint sand specification, and whether the curb cut transition is included in scope or excluded. A bid that is materially lower than others is almost always explained by one or more of these specifications being reduced or omitted. Understanding what is being proposed gives you the ability to evaluate price against actual scope rather than against an unknown.
