Restoration is also Documentation: A Closer Look at Convent Avenue

At Mayta + Sebastian, we believe restoration work is more than just reconstruction—it’s a precise act of stewardship. Our recent project on Convent Avenue in Manhattan exemplifies how careful craftsmanship and thorough documentation come together to preserve the historic fabric of a building.

📸 As part of our scope, we’re replacing damaged terracotta coping units along the parapet, and every phase has been carefully recorded by our project team—from field conditions to final installation.

Key steps in the restoration process include:

🔹 Verification of Rebar Conditions
Before anchoring new units, the team confirmed the diameter and embedment depth of the reinforcing steel to ensure compatibility with original construction and structural integrity. 

🔹 Precision Anchoring with Hilti Products
Using a Hilti epoxy system and a rotary hammer drill, threaded rods were installed into the masonry substrate. This allows us to securely fasten the new terracotta units with confidence. 

🔹 Application of SpecMix Mortar
We selected SpecMix mortar, chosen for its compatibility with historic masonry and its balanced compressive strength—ideal for above-grade applications. 🔹 Sealant Protection for Long-Term Performance
Once set, joints and penetrations are sealed with sealant, providing elasticity and UV/weather resistance to endure New York City’s variable climate. 

👷🏽‍♂️ Every replacement unit was pre-drilled, dry-fit, and aligned on-site before being lowered into place—ensuring both performance and authenticity in restoration.

💬 As architects and facade specialists, we view materials like terracotta not just as finishes, but as historic artifacts that reflect a building’s identity. Replacing them is a privilege—and a responsibility.
