Case Study - Proteus Pro-Felt® - City Tower

City Tower, a private apartment tower block located in Canary Wharf required a new high performance waterproofing system as the existing single ply roof had been damaged beyond repair due to a fire. To provide a cost effective, long term waterproofing solution, Proteus Waterproofing specified a Hybrid Tapered Insulation Scheme with a Proteus Pro-Felt® finish, meeting the client’s specific requirements.

High Performance Waterproofing

As the existing roof was beyond repair, it needed be completely stripped. Pro-Prime® SA and Proteus Pro-Felt® Self Adhesive Underlay were used as a vapor control layer. Proteus Pro-Therm EPS and Proteus Pro-Therm PIR were used for the Hybrid Tapered Insulation Scheme and bonded using Pro-Bond Foaming Adhesive. Proteus Pro-Felt® 3mm Plain Underlay was then fully adhered to the insulation, followed by a final installation of Proteus Pro-Felt® Ultima Plus Fireguard. Proteus Waterproofing worked closely with the Proteus Approved Contractor to ensure the project was delivered to a high standard.
