Nave ceiling ribs and webs at Notre‑Dame

Vault repair is delicate surgery. Teams reconnect ribs, stitch webs, and grout to re‑establish continuity.


🧰 Methods

  • Pins & plates: Stainless connectors for cracked ribs.
  • Web stitching: Needle repairs and micro‑mortars.
  • Monitoring: Sensors verify movement.

📐 Compatibility

  • Mortars: Lime‑based for breathability.
  • Inserts: Reversible where possible.
  • Visuals: Retain grain and color.
