CGI Driveway & Pavers Nationwide

CGI Driveway & Pavers: The Redwood City Owner’s Guide

We stock and install CGI-compatible driveway and paver systems in Redwood City, with paver driveway installations typically running $7,000-$18,000 and concrete driveway work at $4,500-$12,000 depending on substrate condition and pattern complexity. Most CGI paver resets and edge-restraint replacements can be scheduled within 48 hours, and we carry common CGI-compatible edge restraints, polymeric sands, and paver base panels on our Redwood City trucks. Homeowners usually notice the failure first as shifting or dipping pavers near the garage apron or downspout outlets, where the compacted base has washed out or the CGI edge restraint has cracked from seasonal ground movement.

Which CGI Models This Applies To

CGI does not manufacture pavers directly; the brand name appears most often in Redwood City on older paver installations where CGI Building Systems supplied the project package, or where a previous contractor used CGI-specified edge restraints, bedding sands, or base geotextiles as part of a bundled hardscape bid. To identify what you actually have, lift one paver at the edge and check for stamped markings on the plastic edge restraint (common brands are Perma-Edge, PaveTech, or Snap Edge), or look for a project tag near the electrical panel if CGI coordinated the build. The critical compatibility gotcha in Redwood City is the 60mm versus 80mm paver thickness: CGI project specs from 2012-2018 often called for 60mm pavers on residential driveways, which crack under standard Peninsula SUV loads if the base was skimped. We replace these with 80mm Belgard or Techo-Bloc units on a proper 6-inch compacted base, not because the original was wrong on paper, but because Redwood City’s clay-heavy soils in neighborhoods like Stambaugh-Heller hold water and deflect more than the original spec assumed. OEM edge restraints from CGI-era jobs are often brittle by now; we use modern PVC or aluminum alternatives that flex without breaking.

Signs Your CGI Driveway & Pavers Is Failing

• Pavers rocking under foot or tire. The bedding sand has eroded or the base layer has settled unevenly, usually because the original CGI-specified geotextile was pinned too high and allowed fines to migrate into the aggregate base. In Redwood City, this shows up first where downspouts discharge onto the driveway.
• Visible gaps opening between pavers. The joint sand has washed out and the edge restraint has failed, letting the field spread outward. Polymeric sand breaks down faster than owners expect in our climate; the temperature swings between summer highs and winter fog moisture cycle it prematurely.
• Sinking or dipping near the garage apron. The concrete transition was poured without proper expansion accommodation, or the base was compacted in lifts that were too thick to achieve full density. This is the most common callback pattern we see on CGI-coordinated installs from the mid-2010s.
• Edge restraints pulling away from the border. Plastic spikes have rusted through or the restraint itself has UV-degraded. Redwood City’s salt air from the Bay accelerates this; we see it within 8-10 years on south-facing exposures.
• Efflorescence whitening that keeps returning after cleaning. Water is moving through the base and carrying calcium hydroxide to the surface. It is not a paver defect; it signals poor drainage or a base that was not fully saturated before the pavers went down.

Replacement Cost & What’s Included

For a standard Redwood City paver driveway reset or edge-restraint replacement, expect $5,000-$14,000 for full removal and reinstallation, or $2,500-$6,000 for targeted base repair and paver relay in a failing section. The range depends on how much base must be excavated and whether we are matching discontinued CGI-era paver colors or switching to a current Belgard or Techo-Bloc equivalent. Every quote is a flat written price with line-item scope: excavation depth, base material type and lift thickness, compactor passes, paver brand and pattern, edge restraint specification, joint sand type, and sealer if requested. Under Clause 1 of the Haven Standard, that price is fixed before we start; no change proceeds without a signed change order. Our paver work carries the 365-Day Done Right Promise, and you receive a documented photo record of the excavated base condition, the compacted lifts, and the finished surface.

DIY or Call Us?

An owner can safely check whether pavers are loose by hand and whether edge restraints move when pressed; you can also photograph any stamped markings for us to identify. Where DIY goes wrong is in the compaction: a plate compactor rental without proper lift thickness control and moisture content management usually produces a base that looks right and fails in two seasons. Paver removal without breaking the edge restraint is harder than it appears, and relaying a pattern with proper bond lines and joint spacing requires more than a rubber mallet. The real risk is not injury but cost: a failed DIY base repair typically doubles the eventual professional fix because the new sand and partial relay must be removed again. If your CGI-era driveway is shifting, call (650) 560-7228 and we will assess it at no charge, with a written price before any work starts.
