CGI Driveway & Pavers Nationwide

CGI Driveway & Pavers: The Los Angeles Owner’s Guide

CGI driveway and paver installations in Los Angeles typically run $8,260-$21,240 for a complete paver driveway, or $5,310-$14,160 for concrete, depending on substrate condition and access. Rowan Construction Group Los Angeles stocks CGI-compatible edge restraints, bedding sand, and paver units for common series, and we carry the full line of Belgard and Techo-Bloc alternatives when a match isn’t available. Most homeowners notice a problem when settling creates pooling after rain, or when edge restraints pop loose and the field pattern starts to drift - issues that worsen fast in Los Angeles’s clay-heavy soil zones like the Westside basin.

Which CGI Models This Applies To

CGI, or Concrete Graphics Incorporated, produced several paver series through the mid-2000s before shifting focus to commercial imprinted concrete systems. The residential lines most common in Los Angeles are the CGI Cobblestone series, the Roman Circle kit, and the linear Plaza Stone in 4×8 and 6×6 formats. If you’re trying to match existing CGI pavers, check the underside for a molded “CGI” stamp and a two-digit year code - the 02-08 range is typical for Los Angeles installations. The color batch number, usually a four-digit code on the pallet tag or a faded sticker on the edge restraint, matters more than the series name for visual matching.

We’ve learned that CGI’s edge restraint profile, a 6-inch L-shaped PVC with a unique top-lock groove, doesn’t interchange with standard BrickStop or Perma-Edge products. For bedding sand, CGI specified ASTM C-33 washed concrete sand at 1-inch screeded depth, which is coarser than the masonry sand some Los Angeles yards still stock. When we can’t source OEM CGI edge restraint, we fabricate a compatible anchor from galvanized steel and reuse the existing top-lock pins - it’s documented in your photo record, and it holds. We also source from our vetted Belgard and Techo-Bloc lines when a full field replacement makes more sense than chasing discontinued inventory.

Signs Your CGI Driveway & Pavers Is Failing

• Pooling water after light rain. This usually means the bedding sand has washed out or compacted unevenly, creating low spots in the field. In Los Angeles, where irrigation runoff and occasional heavy downpours alternate with dry spells, sand migration happens faster than in wetter climates.
• Edge restraints pulling away from the border. The PVC grows brittle in UV exposure, and the 12-inch spike spacing CGI originally specified isn’t always enough where tree roots or soil heave are active. Once the restraint loosens, the field pavers drift outward and the pattern degrades.
• Individual pavers rocking underfoot. A single loose paver means the bedding layer beneath it has eroded or the paver itself has cracked. Stepping on it grinds sand into the joint and accelerates surrounding failure.
• Weeds or grass sprouting in joints. This signals that polymeric joint sand has washed away or was never installed. Open joints let water penetrate to the base, which in Los Angeles’s expansive clay soils leads to differential settling.
• Visible cracks or spalling on the paver surface. CGI’s older color-through units were durable, but freeze-thaw cycling in the San Gabriel foothills or de-icing salt from adjacent concrete can cause surface delamination. Once the wear layer is breached, moisture accelerates deterioration.

Replacement Cost & What’s Included

For CGI paver driveway work in Los Angeles, our installed pricing follows the ranges below. Every quote is a flat written price with line-item scope before any work starts - Clause 1 of The Haven Standard.

What drives the range: substrate condition (whether we need to remove and recompact base material), access for equipment, and whether we’re matching discontinued CGI inventory or transitioning to a current Belgard or Techo-Bloc equivalent. Our quotes include removal and disposal of failed material, base regrading and compaction to 98% standard Proctor density, bedding sand, paver installation with proper joint spacing, polymeric sand sweep and activation, and edge restraint anchoring. The 365-Day Done Right Promise applies to all paver and driveway work. No change proceeds without a signed change order - the discipline that has kept our projects within a few percent of the agreed price since 2007.

DIY or Call Us?

There’s a safe middle ground for homeowners. You can check for the CGI stamp and year code yourself, photograph the edge restraint profile, and measure the affected area in square feet - that information lets us prepare accurately before arriving. You can also verify whether water pools consistently in the same spots, which tells us whether it’s a localized bedding issue or a broader base problem.

Where DIY goes wrong: lifting pavers without proper base compaction underneath guarantees recurrence, and hand-tamping doesn’t achieve the 98% density we verify with a nuclear gauge. Polymeric joint sand requires precise activation - too much water washes out the binder, too little leaves it powdery and vulnerable. And in Los Angeles, where many CGI installations abut city sidewalk or curb, disturbing the interface without understanding permit requirements can trigger a Department of Public Works correction notice. For anything beyond a single loose paver in an inconspicuous area, the documented approach is worth the call. Reach us at (213) 652-7670 for a free written estimate.
