CGI Driveway & Pavers Nationwide

CGI Driveway & Pavers: The San Antonio Owner’s Guide

CGI driveway and paver replacement in San Antonio typically runs $7,000 – $18,000 installed for a full driveway, with paver patio work landing between $3,500 – $11,000 depending on square footage and base condition. We stock CGI-compatible pavers and the edge restraints, joint sand, and base materials that fail first in South Texas clay soil, and we can usually schedule the repair within a week of the estimate. Most homeowners discover the problem the hard way: a paver sinks after a heavy rain, the edge restraint pops loose along the curb, or the surface starts shifting under the car because the base washed out during a summer storm.

Which CGI Models This Applies To

CGI driveway and paver products come in three main series lines you’ll see across San Antonio: the Estate Series (thicker pavers, typically 60 – 80mm, built for vehicle traffic), the Classic Series (standard 60mm residential pavers), and the Permeable Series (designed for drainage and code-compliant stormwater management in Bexar County). The specific paver you need is stamped on the underside of any loose piece: look for the CGI mold number and the series designation, usually a three-digit code like CGI-E60 or CGI-P80. If you can’t find a loose paver, measure the thickness of the exposed edge – that’s your quickest path to matching the series. One compatibility gotcha we see often: CGI changed their edge restraint profile around 2018, so older installs (pre-2018) need a retrofit restraint rather than the current stock profile. We keep both on the truck. For OEM versus aftermarket, CGI pavers are the safer match for color consistency, but quality aftermarket pavers from Belgard or Unilock can work if you’re replacing a full section rather than patching – the color won’t match perfectly, but the structural performance is comparable when installed on a proper base.

Signs Your CGI Driveway & Pavers Is Failing

• Sunken or dipping pavers near the driveway edges. South Texas clay expands and contracts with moisture, and over time it pushes the base out of level. If one paver drops, the surrounding ones start to follow within a season.
• Edge restraints pulling away from the concrete border or curb. The plastic or aluminum restraint is what keeps the outer course locked in place. Once it separates, pavers start walking outward under vehicle weight, and the pattern breaks open.
• Joint sand washing out after every rain. In San Antonio’s flash-storm pattern, polymeric sand breaks down faster than in drier climates. When joints widen beyond an eighth of an inch, water gets under the pavers and accelerates base erosion.
• Visible cracks across multiple pavers in a line. A crack running through three or four pavers usually means the base shifted underneath, not that the pavers themselves failed. Patching cracked pavers without fixing the base just moves the problem six months down the driveway.
• White haze or efflorescence that won’t scrub off. This is moisture wicking up through the paver and leaving mineral deposits. It’s a sign the base isn’t draining properly, which in clay-heavy San Antonio soil means you’re looking at a base rebuild rather than a surface fix.

Replacement Cost & What’s Included

For a full CGI driveway replacement in San Antonio, plan on $7,000 – $18,000 installed. That covers demolition and haul-away of the old pavers, a rebuilt compacted base (typically 4 – 6 inches of crushed stone plus 1 inch of bedding sand), new edge restraints, the CGI pavers themselves, and polymeric joint sand sealed into place. Paver patios run $3,500 – $11,000 for the same level of work. What moves the number: the size of the area, how much base material needs replacing, whether we find tree roots or utility lines underneath, and whether you’re staying with the existing CGI series or switching to a different grade. We give you a written line-item price before any work starts – you’ll see exactly what the pavers cost, what the base costs, what labor costs, and what the haul-away costs. There’s no verbal estimate that grows on the final bill. The work itself is covered by our written guarantee for 365 days from the completion date: if anything shifts, settles, or fails within that year, we come back and fix it at no charge to you.

DIY or Call Us?

You can safely do the inspection yourself: look for the sinking, cracking, and joint-washout signs above, and check your edge restraints after each big rain. You can also sweep fresh joint sand into dry joints as a temporary hold-over if you catch it early. What we’d steer you away from is pulling up sunken pavers and re-setting them. The failure is almost always in the base, not the paver, and every homeowner who’s tried to re-level a few pavers on a failing base has watched them sink again within months. Rebuilding a base means compacting in lifts, grading for drainage, and getting the pitch right so water moves away from the foundation – that’s not a weekend project, and it’s not worth doing twice.
