Diamond Innovations Roof Refurbishment Project

Project Profile

Project:                Diamond Innovations

Client:                  Diamond Innovations

Scope of project: Approx (2,000m2).

Applicator:         Beton Construction Services Ltd.

Project Description:

The existing felt roofing system of the manufacturing building and security building of Diamond Innovations in Dublin was leaking extensively. The seams between the individual sheets of felt were delaminating and rain water was leaking into the manufacturing area. Beton CSL recommended using a spray applied elastomeric polyurethane system to overcoat the roofs as a more cost effective alternative to stripping and replacing the existing felt system. In addition to this, the CONIROOF 2103 FM system provided the necessary globally recognised Factory Mutual Certification that Diamond Innovations, and the majority of multi-national companies, require for insurance.


  • The manufacturing buildings were continually operational and could not be shut down to carry out the replacement of the existing felt roof.
  • System specified needed to have Factory Mutual approval
  • The project needed to be completed in a short time frame
  • Unusual shapes, penetration and roof openings were to be integrated into the waterproof seal effectively and reliably without additional work or use of prefabricated parts.
  • A seamless surface was required in order to prevent water tracking from one area of the roof to the other underneath the existing sheets of felt
  • Surface needed to be durable enough to facilitate maintenance traffic

Solution:  CONIROOF 2103 Factory Mutual (FM) roofing membrane

System Build Up:

Roof: Built up mineral felt roofing system
