Browse Forums Paving & Concreting 1 Oct 29, 2018 6:37 pm We have recently had our driveway laid with exposed aggregate. It was a big job 213m2, and a couple of trucks were required. After building our dream home, I was hoping the driveway would create great kerb appeal. I am really disappointed with the final product. I am after some advice as to whether this is a normal occurrence with exposed aggregate. The aggregates we chose were 14mm Tarrawingee Stone (95%) and bluestone (5%). Up against the house and garage the exposed aggregate is great and this is what I expected across the entire job. Throughout the job there are patches that have barely any exposed aggregate and certainly not exposing 14mm stones. It isn't that they are different batches because the patches are within the same area that was poured from one truck. We also have these sweeping arcs that are very noticeable when the sun is low because they cast shadows on the concrete. The owner of the company has said they are trowel marks. I thought with exposed aggregate the top layer was blasted away so I don't understand why there would be trowel marks. One of the squares has a number of cracks but they have said they will be filled so not as worried about this. The guy that came to do the acid wash said he isn't sure what happened but events acid wash wasn't doing what he expected and has left marks on the concrete. When they say you can get variance in appearance is it usually this big a variance? Here are some photos. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Above photo is what I expect across the driveway.

My foot is to show the size of the area is the same for perspective. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ 7 comments ⋅ Pin to Ideaboard ⋅ These are the sweeping arcs.

But, ours is only about 50m2.

I had my driveway done a couple years ago. Because of how big the job was, the concreter did it in stages. What I see on your pics is where the water ran off the driveway while they were spraying the concrete to bring up the aggregate. Re: Is this expected with exposed aggregate? 5Jul 14, 2019 1:44 pm Looks like it was poured on a windy day. Possibly hot too. Those types of cracks are from the surface drying too quickly. Looks like they lost control of the job a bit and didn't get the retardant on quick enough. Hence the patchiness. It probably looks good by the house as this was sheltered from the sun and the wind. When there is wind or heat I always wrap up my jobs in poly. This gives it an even exposure. And beyond that. Exposed aggregate shouldn't be poured in 30+degrees anyway. Unless it's a small job or you have heaps of workers to compensate.
