 The conservation and restoration of the Green Wood Cemetery Arch was a design-build project by ICR and ICC.

ICC implemented the conservation treatments for the Green-Wood Cemetery Arch based on the testing and recommendations made by ICR.  The entire structure was cleaned with a non-destructive micro-abrasive cleaning system to remove soiling, biological growth, and efflorescence.

Previous repairs of portland cement were damaging the stone and required removal with bush hammers and chisels. The remaining sound stone was re-tooled to match similar units.  The existing joints were raked and repointed with a compatible mortar.

Severely deteriorated masonry units were replaced with cast stone. The casting mix to match the original stone was designed by ICC. Molds were first taken in the field and then further engineered in our shop to obtain exact profiles where details had deteriorated.

Patches and dutchmen were also installed and cracks were pinned and filled. Finally, an architectural biocide was used to removed any residual biological growth and inhibit new growth.

 Installation of bird netting at the arch bas reliefs was managed by ICC with a specialty firm.
