Paver driveway retaining edging

I moved into a house in Florida 6 years ago and it has a paver driveway. The way they retained the pavers on the sides of the driveway was by pouring a small concrete edging approximately 2" high and 4" wide. It cracked over time from cars parking near it and eventually the pavers separated. (see photos).
I replaced the concrete with aluminum angle with 10" long stakes. It didn't last either. The root cause is my wife pulling into the driveway too fast and too close to the edges.

I'm looking for solutions (besides replacing my wife). Is there a better edging? Is there a product that would adhere the last row of pavers?

Thanks.

 

One thing I often see is that the compacted base layer is stopped right at the edge of the pavers. Then any edging material is only anchored in soft ground and can move more easily. When installing pavers I prepare the base wide enough so that the edging is fully supported by the compacted base plus at least a couple inches. This helps a lot to keep the edges looking good longer especially in sandy soil where anchoring spikes don't have anything solid to bite into.

In your case I would do a test dig at the edge of the driveway and see what you have to work with. You could dig out about a 6" wide strip along the drive. Pull up the edge pavers that have moved which in your case looks like a foot or so into the driveway. Properly install and compact a crushed stone base. This is also a good time to confirm that the base material at the edge is done properly. Then reinstall the pavers and edging. Then backfill and plant grass or sod.

 

Those metal or plastic edging are useless, for patio and walkway just having the surrounding dirt is enough to hold everything in place.

A driveway is different, if the car is turning on it I can see how there could be some side loading.

One suggestion would be to put in concrete but a much bigger cross section than what you had!

 

Yes, the problem is that the crushed stone doesn't go beyond the pavers, this is why I had the angle-aluminum under the last row of pavers so the stakes are in the crushed stone, however, it still was softer than I thought it should be. One problem is the stakes are plastic. I'm thinking of doubling up on the angle-aluminum and using a 2 foot length of rebar to secure them. What do you think?

 

The angle material simply is not strong enough and if your base does not extend past the edge it will eventually fail.

Nice looking drive by the way!

 

Thanks for the compliment on the driveway. Yes, I think the angle-aluminum might be too weak, but it isn't bending, it's moving like the old concrete mentioned in my first thread. Other than an unsightly concrete slab, I trying to find alternatives.

 

If you have any issues related to the driveway paving then you can take the help from blacktop long island which provides the service of the parking paving, driveways paving and more. They have experience in this field and their work result is also good and accurate.
