GAF Driveway & Pavers Nationwide

GAF Driveway & Pavers: The Campbell Owner’s Guide

We stock and install GAF-compatible driveway and paver systems in Campbell, with paver driveway installation typically running $7,000-$18,000 and concrete driveway installation at $4,500-$12,000 depending on substrate condition and square footage. Most GAF paver consultations can be scheduled within 48 hours, and we carry common replacement edge restraints, bedding sand specs, and paver units for same-day repair work. Homeowners usually discover a problem when they notice shifting pavers along the garage threshold, pooling water where the grade used to drain, or weed growth in joints that were tight two seasons ago - all signs the base or edge system has failed.

Which GAF Models This Applies To

GAF’s hardscaping line centers on the GAF Paver Collection, which includes the traditional cobble-style Old World series, the rectangular Modera line, and the permeable AquaPave system designed for stormwater management. Each series uses a proprietary edge restraint profile and specified bedding sand gradation - the Modera line, for instance, requires a 3/4-inch bedding layer over 4-6 inches of compacted Class II base, while AquaPave needs an open-graded stone base for infiltration. To identify your system, check for a GAF stamp on the paver underside or measure the unit: Old World runs 6×6, 6×9, and 6×12 inch modular sizes, Modera is 4×8 inches, and AquaPave is 3 7/8 x 7 7/8 inches.

We source OEM GAF edge restraints and compatible bedding materials; for repairs where GAF has discontinued a specific color lot, we match the closest current production run and document the variance in writing before work begins. Under Clause 1 of the Haven Standard, that written scope includes the exact paver series, color code, and any acceptable substitution - no surprises after the base is opened.

Signs Your GAF Driveway & Pavers Is Failing

• Pavers rocking or tilting underfoot. This usually means the bedding sand has washed out or the base has settled unevenly, often from poor initial compaction or water intrusion through failed edge restraint. In Campbell, we see this frequently near downspout outlets where concentrated runoff undermines the base over two to three rainy seasons.
• Weeds or grass growing through joints. Polymeric sand degradation is the culprit - UV exposure and our dry summers cause it to break down, and once organic material fills the gap, roots follow. The fix is removal, re-sanding with fresh polymeric, and proper activation.
• Edge pavers pulling away from the border. The plastic or aluminum edge restraint has cracked, rotted, or pulled its spikes. This is progressive: one loose edge paver becomes a row, then a section, as lateral load from vehicle traffic pushes outward.
• Standing water or white efflorescence on the surface. Poor drainage from a settled base traps moisture; efflorescence is mineral salts migrating to the surface as that moisture evaporates. Both indicate the base layer needs regrading and compaction.
• Chipped or spalled paver faces. GAF concrete pavers are rated for freeze-thaw, but Campbell’s occasional hard frost combined with deicing salt exposure can cause surface delamination. Spalling limited to a few units is a repair; widespread failure suggests a manufacturing batch issue we document for warranty consideration.

Replacement Cost & What’s Included

The wide range on paver installation reflects three variables: existing asphalt or concrete removal ($1-$2 per square foot), base condition (clay-heavy Campbell soils near the Los Gatos Creek corridor often need additional geotextile stabilization), and paver unit selection. Our quote breaks each line out separately - no lump-sum mystery. The 365-Day Done Right Promise covers settling, joint failure, or edge pullout at no charge if the original scope was followed.

DIY or Call Us?

A homeowner can safely check for loose edge restraints or measure paver dimensions for ordering, but once you’re lifting units and disturbing the base, the risk of creating a larger problem is real. Bedding sand depth, base compaction density (we target 98% standard Proctor), and grade for drainage are not visible once the pavers go back down - and in Campbell, where winter rains arrive hard and fast, a 1% grade error means standing water by January. We bring a plate compactor, laser level, and moisture-conditioned base material to every repair. Call (831) 704-1211 to schedule your free estimate; we’ll scope the work, photograph the condition, and deliver a written price before any tools touch your driveway.
