Roof Refurbishment – Wharfside Point, London

Wharfside Point, a private residential block with a low level green roof and high- level flat roof required refurbishment due to water ingress.

Product brief:

The client requested Proteus Waterproofing to conduct a roof survey which found the lower green roof in poor condition due to lack of maintenance and the waterproofing membrane beyond economical repair. The insulation beneath the green roof was found to be a laid to fall scheme. The high-level roof consisted of a warm roof construction, and while the existing membrane was in poor condition it was still suitable to receive a new waterproofing overlay.

Key Requirements: Quality Control

The Licensed Contractor installed the Proteus Pro-System® Plus to a very high standard, meeting all health and safety requirements needed when working in a busy city centre. This also minimised disruption to other residents.

Key Requirements: High Performance Waterproofing:

Low level roof green Roof: Proteus Waterproofing recommended a complete strip back to the deck and a decision not to replace the green roof was made due to the lack of future roof access, meaning a new green roof could not be maintained.

To ensure rain water discharged to drainage outlets a new Proteus Pro-Therm Tapered Insulation Scheme was installed and the roof waterproofed with the Proteus Pro-System® Plus, fully reinforced seamless membrane providing a durable and cold installed solution.

High – level roof: To resolve the water ingress issue, a new Proteus Pro-System® Plus overlay system was installed.

It is cold applied, eliminating the risk of fire and once cured, provides a completely seamless waterproof protection and has excellent UV stability, making it suitable to use in all climates. Proteus Pro-System® Plus forms a seamless, fully adhered membrane and is BAA Certified for 30 years.
