EUCOPOXY inject. to join a Culvert wall separated from its foundation

[ggc69889]

Please, I would like to get some recommendation to join the wall of a Culvert that was separated from its foundation. The separation is approx. 1-inch, the foundation has settlement. We are planning to use Eucopoxy (EUCO #452) Injection Resin-Structural Bonding Adhesive, however we were told that it can not be pumped. We also are planning to add a foundation slab along the existing, since the existing has settled. We would appreciate if through this helpful forum we can get more or better ideas to fill the 1-inch gap (almost 10' long) between the wall of the culvert and it's foundation.
Thanks!

I would think it would be a good idea to fix the subgrade / settlement issue before tying the wall to the foundation. How about jacking the slab back up using grout?
