Hi everyone,
I'm not sure if this is a DIY project I should be considering over the Christmas break, but I am wanting to relay a section of my paver driveway and rebed it as it has started to walk in the opposite direction to the way we turn out onto the road. The current driveway pavers don't have any edge restraint, which has left me confused on how it has taken nearly 10 years for the pavers to begin to move quite significantly. I assume the original jointing sand has finally been flushed out by some recent big QLD storms.
The current pavers sit on a poured concrete slab. In the photo where I have removed the brick, you can see the slab directly beneath it without any bedding or adhesive. The only pavers that are adhered to the concrete are on the raised section up near the garage. Would using a 3-1 cement sand mix to bond the edge pavers to the concrete base be enough to hold the load of vehicles coming in and out? It’d have to be a thin application as I don’t want the edges to be noticeably more raise than the middle pavers. I'd broom a fine sand between the pavers to help with cancelling out any movement. Or should I also lay down a thin layer of bedding sand to help with drainage as well?
I've looked into edging options, but our grass has sunken on either side of the of the driveway. In the attached photos, ours is the driveway with the tree. I would only want to haunch the pavers if I can hide it. I can potentially cut the lawn into sections and lift the sod, fill to level with top dress and drop the turf back down on top but this is only if I have to. I plan on leveling the lawn in the future but I am short on money and time, and the driveway is actively falling away. I've attached a photo of our neighbours driveway (sorry neighbours) to show what I am trying to avoid with the visible edging. It scares me.
We don't have any MR or HR vehicles, just regular cars.
Happy to hear any suggestions! Thank you very much.
HJi @PaverEnjoyer,
You can use construction-grade building adhesive to bond the pavers to concrete but ensure everything is thoroughly cleaned out.
Trench out and trowel in ready mixed concrete and smooth off.
If needed backfill with soil to encourage grass growth.
Cheers
Hello @PaverEnjoyer
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your driveway.
It's great that you've received excellent advice from @AlanM52. I agree with the suggested adhesive to be used on your pavers. I propose looking at the Sika 300ml Concrete Grey Sikaflex 11FC Purform. This adhesive has a bit of flex in it which I believe is better in the long run rather than an adhesive that dries hard. Once the adhesive breaks due to stress it will not bond together again. But a flexible adhesive will be able to take the stress.
Your plan of re-bedding the corner is a good idea. I also agree with haunching the edge if it can be hidden under the soil of the lawn. This haunching will provide extra support to the pavers should your vehicles pass over this particular section. Have a look under the corner section first and investigate further. Once you see the overall situation, you'll have a better idea of what repair steps you'll need to take.
Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.
If you have any other questions we can help with, please let us know.
