Here is an example of some Tuckpointing done on the stone foundation of an INHS owned building at the corner of N. Plain St. and Seneca St.
While it might not obvious at first this work was meant to simulate well cut Ashlar stonework. What is interesting here is use of a straightedge to produce crisp 90° angles and sharp straight ribbons. Also, the work done here is not a crisp bead as in other examples but more of a true flat ribbon, which is more akin to tuckpointing associated with brickwork.
With this level of decay only a small portion of the original article is left behind and is clearly in need of a repointing campaign, and should be finished in a true tuckpointed finish.
