Concrete block and retaining wall

The retaining wall which we are about to build is joining up to a concrete block wall. When they join each other at the section what should be done to join these two areas together. Any pictures or Info will be helpful. Thanks

Where your srw meets the concrete wall 90 it and build a wall along the concrete. Pinning the corner together. Basically as a dead men

I wouldn't go pinning a retaining wall to a poured wall if your in an area that the ground freezes. the concrete wall at least where Im at is more than likely poured below frost and dose not move when the ground freezes, while a retaining wall is designed to move with the frost. 90ing the wall is a good solution Im not sure where your at or what the climate is like there.

I was talking about pinning the 90 together. We drill all of our corners and rely on the pins instead of glue. Definitely make the wall free floating from the concrete.

We use a lot of versa lok. So we have tons of versa pins laying around. 1/2" masonry bit on our hammer drill and usually put 3 pins per corner block.
