Belgard Home Additions & ADU: The Austin Owner’s Guide
We install and service Belgard hardscape systems for home additions and ADU projects across Austin, with most accessory dwelling unit builds running $90,000 to $220,000 and standard home additions landing between $45,000 and $130,000. The parts that fail on these jobs are usually not the Belgard pavers themselves but what sits underneath them: base material, edge restraints, and drainage layers. When an Austin homeowner calls us about a Belgard addition or ADU problem, it’s almost always because the pavers have shifted, settled, or started separating at the edges.
This page covers what goes wrong, what it costs to fix in Austin, and how to know whether you need a repair or a full rework of the hardscape around your addition or ADU. We’re an independent Austin contractor, not a Belgard dealer or affiliate, but we’ve installed and repaired enough Belgard product in Central Texas to know exactly how it behaves in our soil and heat.
Which Belgard Models This Applies To
Belgard’s paver lines used on Austin additions and ADUs fall into a few families: the Dublin, Catalina, Mega-Arbel, and Old Towne series are the ones we see most on driveways and walkways leading to new structures, while the Lafitt and Holland lines show up on patios and ADU courtyards. The compatibility issue that trips up most Austin owners is thickness. Belgard sells pavers in 60mm and 80mm profiles, and the 60mm residential pavers are not rated for the same loads as the 80mm commercial-grade ones. If an owner buys a few replacement 60mm units to patch an 80mm surface, they’ll crack under the weight of a vehicle or a heavy outdoor kitchen within a season.
Here’s the checkable spec: Belgard’s own tech documents rate 60mm pavers for pedestrian and light use only, while 80mm pavers handle vehicular loads. We check the back of the paver. Belgard stamps a mold code and series identifier on the underside of most units, and matching that code matters more than matching the color name, because pigment runs vary slightly between manufacturing years. For aftermarket equivalents, we generally tell Austin homeowners to stick with genuine Belgard units if the surface is a visible showpiece. The color consistency and edge bevel on knock-offs never quite match, and once the sun hits an Austin patio for three summers, the mismatch becomes obvious before the crack does.
Styles & brands we work with
Signs Your Belgard Home Additions & ADU Is Failing
- Edges pulling away from the house or curb. The edge restraint has failed or was never installed properly. Without it, the outer pavers drift outward under foot traffic and Austin’s expansive clay soil movement, and the gap just grows.
- Low spots collecting water after rain. This is base failure underneath the pavers. In Austin, the culprit is often the shrink-swell cycle of our clay soils, especially if the base was never compacted in lifts on the original build.
- Individual pavers rocking when you step on them. The bedding sand has migrated or washed out from below, leaving the paver unsupported at the corners. It will crack eventually if the rocking isn’t corrected.
- Hairline cracks spreading across a paver surface. Usually a load problem: a 60mm paver carrying something it wasn’t rated for, or a tree root pushing up from below that nobody addressed before the build.
- Weeds sprouting between paver joints every few weeks. Joint sand has degraded or washed out. In Austin’s heat, polymeric sand breaks down faster than most owners expect, and once the joint is open, the pavers start shifting laterally.

AfterReplacement Cost & What’s Included
For a Belgard hardscape repair tied to an Austin home addition or ADU, the work typically lands between $3,500 and $11,000 depending on the surface area, the depth of the base failure, and whether we’re pulling and re-laying the entire field or repairing a section. A full paver patio re-installation on an ADU courtyard runs $3,500 to $11,000. If the issue is isolated to a walkway or a set of steps, you’re often looking at the lower end of that range.
What drives cost here isn’t the pavers themselves. They’re usually $4 to $8 per square foot in Austin. The real cost is the labor to lift, sort, clean, and re-lay them, plus the base material and compaction time. Our written price includes the full scope: removal of the affected pavers, base repair or replacement at the proper depth, new edge restraints, new bedding sand, and re-laying with fresh joint sand. Every hardscape job we do in Austin carries our written guarantee, and if the repair doesn’t hold, we return at no charge. You get the price in writing before we touch the first paver, and it doesn’t change once work starts.
DIY or Call Us?
You can safely check a few things yourself: look at whether the edges are still restrained, mark the spots where water pools after a rain, and check the underside of a loose paver for the mold code. That information helps us quote the job over the phone faster. What you shouldn’t do is start lifting pavers and re-laying them on your own. The moment you pull a paver out of its bed, you disturb the sand layer and the edge restraint integrity, and a small settlement problem becomes a full re-level. Most Austin homeowners also don’t own a plate compactor, and uncompacted base under Austin clay will fail again within a year.
If your Belgard surface is moving, call us at (903) 623-1966. We’ll look at it, tell you exactly what we found, and give you a written price before any work starts.
FAQs
Pavers themselves will go 25 to 40 years in Austin’s climate, but the base and joint system underneath them typically needs major attention every 10 to 15 years because our clay soil expands and contracts through the wet-dry cycle. Call (903) 623-1966 and we’ll tell you whether your surface needs a repair or a base rebuild.
Yes, if the problem is localized and the edge restraints are still intact we can pull and re-lay a section, but keep in mind that the repaired area may settle at a slightly different rate than the surrounding pavers in the first year in Austin’s soil. Call (903) 623-1966 for a quote on your specific repair.
Most repairs on an Austin addition or ADU run one to three days depending on the area and the base work required, with the caveat that compaction and sand-setting need dry weather to hold properly. Call us at (903) 623-1966 and we’ll give you a timeline in the written estimate.
We keep common Belgard series colors and sizes in stock on our trucks for quick repairs, and we source less common mold codes directly from Austin Belgard distributors within a few days. Call (903) 623-1966 with the mold code from the back of your paver and we’ll confirm availability.
If your Belgard hardscape is shifting, settling, or cracking around your Austin home addition or ADU, call (903) 623-1966 for a free estimate. We’ll put a written price in your hand before any work begins, and Isaac Pruett will personally walk the site with you to figure out what’s actually wrong and what it actually needs to fix it right.
