GAF Driveway & Pavers Nationwide

GAF Driveway & Pavers: The Pomona Owner’s Guide

GAF manufactures Belgard-brand pavers and driveway systems under its roofing and exterior solutions umbrella, and we stock and install GAF-compatible Belgard pavers, permeable paver grids, and edge restraints across Pomona. A typical Belgard paver driveway installation in Pomona runs $7,000-$18,000 depending on pattern complexity and base preparation needs. Most Pomona homeowners notice the failure during our dry-hot summers when settlement cracks widen or edge restraints pop after winter rains undermine the bedding sand.

Most calls we get in Pomona start the same way: a dip developed where the garbage truck turns around, or the soldier course along the garage slab has shifted an inch and the gap is collecting weeds. Sometimes it’s spalling on a driveway that was sealed with the wrong product five years back. These aren’t cosmetic issues - they’re structural warnings that the base, the edge system, or the paver itself is giving way.

Which GAF Models This Applies To

GAF’s hardscape line is branded Belgard, and the product families that show up most often in Pomona are the Belgard Catalina (the standard 60mm residential paver), Belgard Dublin Cobble (tumbled, 80mm for driveways rated to H-20 vehicle loads), and the Belgard Aqua Bric permeable series used for Pomona’s rebate-eligible stormwater management installations. The Belgard Tandem Wall edge restraint system pairs with these for the raised soldier course that separates driveway from softscape.

To identify your paver, flip one over if you have a spare. Belgard stamps the mold number and production date in a recessed rectangle - look for “BEL-” followed by a four-digit series code. The edge restraint is harder: Tandem Wall units have a vertical pin connection visible from the back, while the older Belgard Anchor system used a horizontal fiberglass rod. Mixing Anchor pins with Tandem Wall units is a compatibility gotcha we’ve found on three Pomona resales this year - the profiles don’t lock, and the edge drifts within two seasons.

We source OEM Belgard through GAF’s regional distribution in Rancho Cucamonga, and we also stock Unilock and Techo-Bloc equivalents where the original pattern is discontinued. For edge restraints, we keep Perma-Edge aluminum and EdgePro PVC on the truck - both meet Caltrans spec for flexural strength and won’t rot like the pressure-treated 2x4s some Pomona installers used through the mid-2010s.

Signs Your GAF Driveway & Pavers Is Failing

• Sunken or dipped sections, especially near the apron or turn radius. This indicates base failure - usually decomposed granite that wasn’t compacted to 95% standard Proctor density, or water infiltration through a failed seal joint. In Pomona’s clay-heavy soils near Ganesha Park, we’ve seen 4-inch drops where the subgrade wasn’t geotextiled.
• Edge restraints bowing outward or completely detached. The bedding sand has migrated, or the spikes holding the restraint have corroded. Tandem Wall systems fail at the pin connection first; you’ll see a hairline crack running vertically through the interlock.
• Pavers rocking underfoot or sounding hollow when tapped. Bedding sand has washed out, likely from a failed joint sand seal. Pomona’s 0.4-inch average annual rainfall doesn’t sound like much, but it concentrates in January storms that find any gap.
• White efflorescence blooming across the surface. Calcium hydroxide migrating from the concrete base - common on Belgard Catalina installations where a vapor barrier was omitted over expansive soil. It’s not structural yet, but it signals moisture is moving through the assembly wrong.
• Spalling or flaking on the paver face, especially on darker colors. Wrong sealer was applied (acrylic over wet cast concrete), or the paver was salt-finished and the surface skin is delaminating. We’ve replaced entire driveways in the Lincoln Park corridor where a “maintenance company” applied Thompson’s Water Seal every spring for four years.

Replacement Cost & What’s Included

The wide range on full installations comes down to three things: how much existing material we can salvage (Belgard pavers are reusable if lifted carefully), whether the subgrade needs geogrid reinforcement for Pomona’s expansive clay, and access - a driveway off Phillips Boulevard with a retaining wall on one side takes longer than a flat pad in the Village.

Every quote we write itemizes demolition, base prep, materials, and labor separately. Under Clause 1 of the Haven Standard, that written price is locked before we start; no change order gets signed without your initials. The 365-Day Done Right Promise covers settling, joint sand loss, and edge restraint movement - the things that separate a paver job that lasts from one that looks good for six months.

DIY or Call Us?

Here’s what you can safely check yourself: lift one paver from an inconspicuous corner and photograph the base layer. If you see mud, organic debris, or standing water, the drainage plane has failed. Tap surrounding pavers with a rubber mallet - a hollow sound means bedding sand has washed out. These observations help us scope the repair before we arrive.

Where DIY goes wrong: relaying pavers without regrading the base to 1/4-inch per foot slope away from the foundation. We’ve been called to Pomona jobs where a homeowner spent a Saturday resetting pavers level, only to trap water against the stucco and rot the sill plate. Base compaction requires a plate compactor rated to 5,000 lbs cf - rental units often aren’t - and joint sand must be polymeric (activated with water) to lock properly. Edge restraint installation looks simple until you’re trying to drive 12-inch spikes through decomposed granite with a hand sledge at 102 degrees.
