How to repair Pebblecrete driveway?

Hi, I have an old (1980s) pebblecrete driveway on a downward slope in Queensland that is in need of repair.

The cost to dig it up and repour a concrete driveway is $10k.

I've been researching concrete resealers, epoxy sealants, and other polymer coatings but am seeking advice if any of these options are durable enough to warrant the investment? I've also researched all the preparation steps.

I'd appreciate experienced advice on steps to take a products that work? Or do I just bite the bullet and reconcrete?

Thanks in advance

Michael

Welcome to the Bunnings Workshop community Michael (@GCGuy). It's wonderful to have you join us, and many thanks for your question about a Pebblecrete driveway.

You might like to post some images of the driveway so our members have a better understanding of what you're working with. Let me know if you need a hand uploading some pictures.

It really comes down to how degraded the driveway is and whether any repairs would offer a lasting solution or just delay the inevitable deterioration. If the Pebblecrete is only surface-level damaged or cracked, products like concrete resealers, epoxy sealants, or polymer coatings might provide a temporary fix, helping to fill in small cracks and protect the surface from further weathering. However, these products are generally not designed to fully restore a driveway and may not offer long-term durability, especially if the driveway is subject to heavy traffic or harsh weather conditions in Queensland.

If the driveway has significant structural damage, like deep cracks, shifting, or large sections of the Pebblecrete coming loose, these products may not be effective enough to address the underlying issues. In that case, repairs could end up being a stop-gap solution, requiring further maintenance down the line, and you may find it more cost-effective to invest in a full re-pour.

Considering the substantial cost of digging up and replacing the driveway, it’s worth evaluating whether the current condition of the driveway warrants the investment in a full replacement or if a repair will suffice for a few more years before needing replacement. If the driveway is fundamentally sound and only showing surface wear, a good resurfacing might be worth considering, but if the integrity of the base layer is compromised, a re-pour might be the more lasting solution.

Please let me know if you have any questions.
