ᐅ Attaching Curbstones to the Foundation – What is the Recommended Method?

Hello everyone,

We have just started installing the curbstones for the terrace, around the house, and for the driveway.

At the garage, there is a cantilevered roof supported by a steel post. This post is placed on and fixed to a foundation.
Since the garage is built on the property boundary, the curbstones for about 2 meters (6.5 feet) also need to be placed on the foundation and additionally trimmed in height, otherwise the curbstones would be too high.

The problem is that we cannot set the curbstones here in a concrete bed. Wedges could only be inserted from our side (because of building on the boundary). Do you have any ideas or suggestions on how to secure the curbstones so that we can pave the driveway afterward?

I hope the foundation where the post is fixed can be seen in the picture.

One idea might be to fix the curbstone to the foundation with stainless steel brackets or something similar, then wedge it with concrete where possible.

Do you have any other ideas or suggestions?

Thanks in advance.

Best regards,
Tobias
