Food Processing Plant: Roof Cleaning, Coating and Gutter Lining

A food and beverage processing company had three interconnected cement-sheet roofs, about 32,000 sq ft in total, that leaked at many points. For years the leaks had been patched as they appeared, but the causes were never fixed, so the leaks kept coming back, disrupting work inside and pushing up maintenance costs.

The sheets and their bolt fixings had worn down through years of weather, and heavy storms had made the damage worse. The company needed a long-term waterproofing solution, but the landlord would not allow a new roof to be built over the existing sheets.

• Controlled cleaning: all three roofs were pressure-washed, with the wastewater contained and filtered to 5 microns to protect the surrounding environment.
• Preparation and coating: after preparation, the roofs were coated with a waterproofing system that sealed the aged sheets and their bolt fixings under one continuous, weather-resistant layer.
• Gutter lining: the gutters were cleaned out and relined with a one-piece membrane, stopping the existing leaks and removing the joints where gutters usually fail.

• A long-term waterproofing solution without a roof-over, as the landlord required.
• An end to the cycle of reactive repairs.
• Better drainage through relined gutters.
• Delivered on budget despite the weather delays.
