Metal stitching process
The Metal stitching process is based on sound engineering principles which have been accepted for more than a century.



1. Using a drill jig. rows of blind holes are drilled perpendicular to the direction of the crack, each row to act as a key.
2. The intermediate partitions are removed with pneum chisel.
3The keys are driven into the openings and caulked



4. Holes for screws are drilled along the crack between the keys.
5. The screws are fitted to ensure they overlap, effetting a seal along the fracture.
6. Finally, the entire installation is caulked to ensure stabilty and pressure tightness.
