How to fix a aggregate driveway?

Jash1

Please guide me I desperately need your

Not even a year ago we hired someone to do the composed aggregate drive way concrete flooring at my front yard ( photo attached) but he did not do proper sealing and as a result stones coming off heavily.

I need advice how to fix the floor interms of putting back stones to floor missing areas plus some areas has a 10 cents coin size hole as well. How can I fill them up and finally once all do repairing done I have to do sealing as well.

So cleaning, repairing, filling the holes and sealing the floor. These tasks needs to be done. Please guide me What quality products and materials I need to use for a better result ).

Please advice me and put your valuable knowledge to guide me.

Much appreciate your efforts.

Welcome to the Bunnings Workshop community @Jash1. It's brilliant  to have you join us, and many thanks for your question about aggregate driveways.

PebbleCrete is a type of exposed aggregate finish that uses small decorative pebbles mixed into a clear resin binder. When applied correctly, the resin locks the stones together and creates a hard, durable surface that’s both attractive and slip-resistant. In your case, since the stones are coming loose, it sounds like the original installer either didn’t use enough resin or didn’t seal the surface properly, leaving the pebbles poorly bonded.

Unfortunately, there isn’t a D.I.Y.-grade resin available that can be used to repair or rebind loose pebbles in an existing PebbleCrete surface. The resins used are typically commercial products that require professional application to ensure proper curing and bonding.

For the 10-cent-sized holes, you could carry out small cosmetic repairs by mixing a bit of cement mortar, filling the holes, and then pressing some similar-sized black pebbles into the top before the mortar sets. This won’t perfectly match the surrounding finish, but it should disguise the damage reasonably well and help prevent further wear in those spots.

As for the worn or patchy areas where pebbles have come away, there isn’t really an effective D.I.Y. method to patch those sections. The existing resin layer in those areas is likely still present, which means new PebbleCrete or resin wouldn’t bond properly, and the patch would sit proud and look uneven.

Given that the surface is already deteriorating in multiple spots, it’s best to contact a few PebbleCrete specialists or decorative concrete restoration companies for on-site advice and quotes. They’ll be able to assess how extensive the resin failure is and whether resurfacing or resealing the entire driveway is the better long-term solution. Even if repairs are possible, it’s important to understand that once PebbleCrete starts breaking down, the rest of the surface often follows within a short period, so professional input would give you the clearest picture of your options.

Please let me know if you have any questions.
