Metal Roof Rehabilitation & Waterproofing Project – Al Helw Tower

EMC carried out rehabilitation and waterproofing works for the metal roof of Al Helw Tower in Damietta, for Zakaria Al Helw Contracting, covering a total area of 370 m².

The works included treating damaged sections, joints, and vulnerable areas, followed by the application of a reinforced acrylic waterproofing system using fleece and fiberglass to provide comprehensive protection against water ingress and weather exposure.


Scope of Work

  • Site inspection and identification of damaged and vulnerable roof areas.

  • Cutting and removal of severely deteriorated metal sections.

  • Installation and fixing of new metal sheets in damaged areas.

  • Securing loose sheets and open joints using metal fasteners.

  • Filling joints, gaps, and openings with epoxy putty.

  • Reinforcement of damaged areas and joints using fiberglass and epoxy coatings.

  • Treatment of vulnerable areas with fiberglass-reinforced acrylic material.

  • Reinforcement of roof upstands and corner connections.

  • Installation of the fleece layer and application of acrylic waterproofing material.

  • Application of a second acrylic waterproofing coat.

  • Final inspection and handover following completion of the waterproofing works.

Case Study

The Challenge

The main challenge was the deteriorated condition of the metal roof, including severe rust and corrosion, perforated metal sheets, open joints and gaps allowing water ingress, as well as vulnerable corners, connections, and upstands that required rehabilitation before applying the waterproofing system.

The Solution

Severely deteriorated metal sections were removed and replaced with new sheets, while loose areas were secured and gaps were sealed using epoxy putty. Vulnerable joints and upstands were reinforced with fiberglass, followed by the installation of fleece and two layers of acrylic waterproofing material.

The Result

The metal roof was rehabilitated and protected with an integrated waterproofing system, helping prevent water ingress while protecting joints, vulnerable areas, and treated sections against direct weather exposure.
