This is for a job in Edmonds WA that we matched the Fieldstone in the front of the house to the newly added deck space in the back. The Field Stone works with larger area's because the pieces are large. One of the problems with this install were the metal ties in the foundation. You need to remove them from the exterior because as they rust they can cause the install to fail. It also had a water proofing material on the concrete wall. For a proper install we needed to install metal mesh with a scratch coat. Without that black water proofing material we could have just gone over the concrete.  Good luck with your next project. If you have any questions about an install just ask. We have a mason that can help.
