GAF Driveway & Pavers: The San Antonio Owner’s Guide
GAF driveway pavers and paver-compatible drainage components in San Antonio typically cost $7,000 – $18,000 for a full installation, with replacement or repair of individual failed sections running far less depending on the scope. We stock GAF-compatible paver materials and the drainage channels and underlayment products that pair with them, and our crew in San Antonio can assess a failing section, match it, and give you a written price before any work starts. The way most owners find us is through water: pooling at the edge of a driveway, pavers shifting after a heavy San Antonio rain, or a sand-filled joint washing out faster than it should after the July downpours we get every summer.
That last one is the tell. GAF’s paver systems are designed with permeable drainage in mind, but when the base wasn’t prepped for San Antonio’s clay-heavy soil or the edge restraint fails, water gets under the pavers and starts moving things. We see it most often in older neighborhoods like Terrell Heights and Monte Vista, where driveways were poured decades ago and then topped with pavers without reworking the drainage.
Which GAF Models This Applies To
GAF offers paver products under its Timberline and Cobra line extensions for residential hardscape, along with a set of drainage channels and edge restraints sized to work together. The critical thing to know is that GAF’s paver profiles are not universal: a 2-3/8″ thick paver from one series will not sit level next to a 2″ paver from another. If you’re replacing a section, the thickness, bevel profile, and color lot all have to match or the repair will look like a patch.
Here’s what we check on every San Antonio job: lift one paver near the edge, measure its thickness with a caliper, and look for a molded mark on the underside. GAF stamps most of its pavers with a series code and size in millimeters, not inches. Write that code down. Then count the joint width: GAF’s permeable systems run 3 – 5mm joints that let water pass through, while their traditional systems run tighter. Mixing the two creates drainage dead spots. We also always confirm whether the original install used a GAF edge restraint or a generic plastic one. The generic versions fail in San Antonio’s clay soil within a few seasons because they don’t hold against the expansion we get from our freeze-thaw cycles in January and February.
We stock OEM GAF-compatible pavers, joint sand, and edge restraints on our trucks. For aftermarket equivalents, we carry a limited set from a Texas supplier that matches common GAF profiles, but we will tell you when an aftermarket option will fade differently or sit a millimeter off. Sometimes the honest answer is to order the exact GAF SKU and wait a week.

Signs Your GAF Driveway & Pavers Is Failing
- Water pooling at the driveway edge after a normal rain. The drainage channel beneath the pavers is clogged or was never graded correctly. In San Antonio’s clay soil, this water saturates the base and causes the pavers to sink unevenly within a season.
- Pavers shifting or rocking underfoot near the street. The edge restraint has failed or was never installed. A driveway that meets the curb carries tire load at its weakest point; once the restraint lets go, the whole edge row starts walking.
- Sand-filled joints washing out repeatedly. The joint sand isn’t locking properly. On permeable GAF systems, this usually means the wrong sand was used or the base layer has compacted unevenly, so water channels through the joints instead of through them evenly.
- Low spots that hold water for days after rain. The base underneath has eroded. This is the most common failure we fix in San Antonio, especially in areas like Alamo Heights where older storm drains move water slowly.
- White haze or color fading on pavers near the garage door. Efflorescence from trapped moisture rising through the paver, common when a driveway has no drainage path at the garage apron. It isn’t always structural, but it tells you water is sitting under the pavers where it shouldn’t.

AfterReplacement Cost & What’s Included
A full GAF-compatible paver driveway in San Antonio runs $7,000 – $18,000 depending on square footage, access, and whether the existing base can be reused. Driveway replacement if the entire base has failed lands at $5,000 – $14,000. For a partial repair, where we match an existing GAF section and rework the drainage, you’re usually looking at a few hundred to a couple thousand dollars. We give you a written price before any work starts, every time. No numbers change after the crew arrives.
What’s included in that number: the pavers or matching pieces, base aggregate if needed, joint sand, edge restraint, and labor. We also include the clean-up: shoe covers and drop cloths on any interior path we walk, and a photo of the finished work area before we leave. That’s the Cedarwell Care Promise, and it applies to every project we take on in San Antonio. The 365-Day Done Right Promise covers the completed paver work too. If it’s not done right, we make it right.
DIY or Call Us?
You can safely check a few things yourself: whether water is pooling in identifiable spots, whether pavers are rocking underfoot, and whether joint sand is washing out. If you want to measure a paver’s thickness and look for the GAF mold code on the underside, that helps us quote faster too. What we don’t recommend is lifting and re-setting a large section of pavers without reworking the base. Once you pull up a row, you’ve broken the compaction, and the repair becomes a different job than you started. The same goes for re-sanding joints: if the base is the problem, new sand buys you a few months, not a fix.
If you’re in San Antonio and want an honest read on whether the paver needs a patch or a base rework, call us at (432) 233-0976. Graham Stein will look at it, write down the scope, and give you a price. Write it down, price it once, do it right.
FAQs
GAF driveway pavers in San Antonio typically last 20 – 30 years when the base is prepped correctly for clay soil and the drainage works as designed. The base, not the paver, is what fails first in our climate. If water saturates the base repeatedly, you can see shifting within five years. Call (432) 233-0976 and we’ll tell you honestly whether your base is the problem before you spend money on pavers.
Yes, in most cases a failing GAF paver section can be repaired by lifting the affected pavers, reworking the base and drainage, and re-setting the same pieces with fresh joint sand. If the pavers themselves are cracked or worn, we match replacements by thickness and GAF mold code. Call (432) 233-0976 for a written price on the repair scope.
A partial GAF paver repair in San Antonio usually takes one to two days depending on the size of the affected area and how much base rework is needed. A full driveway replacement runs five to seven days including aggregate, compaction, and paver setting. We schedule around your family’s quiet hours where we can.
We stock common GAF-compatible pavers, edge restraints, and joint sand on our trucks, and we order exact-match GAF SKUs when a repair needs a specific thickness or color lot. If you have the mold code from the underside of a paver, share it and we can confirm availability before we come out. Estimates are free: (432) 233-0976.
