CGI Driveway & Pavers: The Pomona Owner’s Guide
We stock and install CGI-compatible driveway and paver systems in Pomona, with typical installed replacement costs running $5,000-$14,000 for a full driveway replacement and $7,000-$18,000 for paver installations depending on substrate condition and access. Most CGI paver resets and edge restraints can be completed same-day once we verify your series and substrate type. Homeowners usually discover the failure when individual pavers start rocking underfoot, edge restraints pull away from the border, or water begins pooling in sections that used to drain clean - all signs the bedding layer or interlock system has shifted.
Which CGI Models This Applies To
CGI produces several paver and hardscape lines, and the critical detail is whether your installation used their interlocking concrete paver system with plastic edge restraints or their older poured-concrete border specification. The model designation is usually stamped on the paver underside or noted on your original project documentation - look for a “CGI-” prefix followed by a four-digit series code. We see the CGI-2200 and CGI-3400 residential series most frequently in Pomona neighborhoods near the Fairplex corridor and north of Mission Boulevard, where installations from the 2015-2019 building wave are now hitting the 8-10 year mark.
OEM CGI edge restraints and bedding sand are available, but we often specify equivalent-grade aftermarket materials from Belgard or Techo-Bloc when the original CGI part is back-ordered or discontinued. The aftermarket decision hinges on two factors: whether your warranty requires genuine CGI components, and whether the paver thickness matches the restraint channel depth - a 60mm paver paired with a 80mm-spec edge restraint will rock within a season. We measure twice, then we can talk.
Signs Your CGI Driveway & Pavers Is Failing

- Individual pavers rock or click when stepped on. This means the bedding sand has washed out or compacted unevenly, breaking the interlock that distributes load across adjacent units. In Pomona, this often follows the heavy winter rains that run off the San Gabriel foothills and saturate clay-heavy soils.
- Edge restraints pull away from the border, creating a gap. The plastic or concrete restraint has lost anchorage, usually because spikes have corroded or the concrete haunch has cracked. Once the edge goes, the field pavers migrate outward.
- Water pools in sections that previously drained. The bedding layer has settled or eroded, creating low spots. On CGI installations with open-graded base, this signals a clogged drainage course or failed geotextile separation.
- Sand washes out from joints, leaving gaps between pavers. Polymeric sand has degraded or was never properly activated. Pomona’s summer heat cycles can accelerate this if the sand was installed damp.
- Surface spalling or corner chipping on individual pavers. This is material failure, not installation failure - de-icing salts or freeze-thaw cycling on a saturated paver. CGI’s denser mixes resist this better than generic concrete, but no concrete is immune.

AfterReplacement Cost & What’s Included
| Service | Price Range in Pomona |
|---|---|
| Driveway replacement (concrete) | $4,500-$12,000 |
| Driveway replacement (pavers) | $7,000-$18,000 |
| Driveway replacement (general) | $5,000-$14,000 |
| Driveway sealing | $250-$700 |
| Paver patio installation | $3,500-$11,000 |
The range depends on four factors: whether we can reuse the existing base or must excavate to grade, the paver material cost per square foot, access for equipment (narrow Pomona lots sometimes require hand work), and whether permits are required for expansion or drainage modification. Under Clause 1 of The Haven Standard, you receive a written flat price before any work starts - every line item specified, no call-for-pricing. The quote includes parts, labor, disposal, and a documented photo record of the substrate condition before we cover it. Our 365-Day Done Right Promise covers the installation; manufacturer defects in the CGI pavers themselves are handled through their warranty channel, which we document for you.
DIY or Call Us?

An owner can safely check three things: whether the paver model stamp is visible for identification, whether the drainage pattern has changed visibly, and whether the edge restraint is loose enough to lift by hand. What you cannot safely assess is the base condition beneath the bedding layer - and that’s where DIY resets fail. Pulling pavers without verifying the compacted aggregate base invites a second failure in six months, and improper compaction of replacement bedding sand voids most manufacturer warranties.
Rowan Construction Group Pomona is an independent service provider, not affiliated with CGI. We carry CGI-compatible edge restraints, bedding materials, and polymeric sand on our trucks, and we verify base compaction with a plate compactor and density check before resetting. If your pavers are shifting, call (626) 606-1081 to schedule your free estimate - we’ll identify the series, photograph the substrate, and give you a written price before any work starts.
FAQs
Properly installed CGI concrete pavers last 25-30 years in Pomona’s inland Southern California climate, though the polymeric sand jointing and edge restraints typically need attention at 8-12 years. The intense summer heat and occasional heavy winter rains accelerate surface weathering compared to coastal installations. Call (626) 606-1081 for an exact quote on restoration - estimates are free.
Partial repair is viable when the base is intact and fewer than 15% of pavers are affected - we lift the affected area, regrade the bedding, and reset with new edge anchorage. Full replacement becomes necessary when the base has settled differentially or drainage has been compromised across the field. We document both options with photos and a written price for each before you decide.
A typical residential driveway reset takes 2-3 days: one day for excavation or lifting, one for base preparation and compaction, and one for laying and jointing. Full replacement with excavation runs 4-5 days depending on utility clearance and soil conditions. We provide a written timeline with the price, and no work proceeds on any change until the change order is signed.
We stock CGI-compatible edge restraints, bedding sand, and polymeric sand in standard profiles; specific paver colors and series may need 2-3 day ordering if your original run has been discontinued. We verify stock against your series stamp during the estimate visit so there are no surprises when the crew arrives. Call (626) 606-1081 to schedule - estimates are free.
