Industrial waterproofing covers the roofs, gutters, floors and special areas of wide-span buildings such as factories, warehouses, logistics centres, cold stores, retail parks and agricultural facilities. A single leak can damage machinery, stock and production continuity.
AquaSeal works with PVC and TPO membranes, liquid polyurethane and polyurea on industrial roofs, and re-details fixings, laps and gutters on sandwich panel roofs. We phase the work around the facility's operations and plan work at height and safety measures from the start.
Why is industrial waterproofing different?
Industrial roofs can span thousands of square metres and are more exposed to wind uplift, thermal movement, heavy rain and snow than residential roofs. When gutters overflow, water falls straight into production areas, while floors are stressed by forklift traffic, oils and chemicals.
Material selection is therefore driven by wind uplift calculations, chemical resistance, fire performance and ease of maintenance. Working while the facility stays in operation requires careful site organisation.
Industrial waterproofing: where we apply it
- Factory and production facility roofs
- Logistics centres, bonded warehouses and stores
- Sandwich panel and profiled metal roofs
- Roof gutters, valleys and rainwater systems
- Chemical, acid and wastewater basins
- Cold stores and food facilities
Systems we use
- PVC and TPO membrane systems
- Lightweight, durable single-ply roofing, mechanically fixed over insulation boards and hot-air welded.
- Polyurea and liquid polyurethane
- Fast spray-applied, seamless coatings with high mechanical strength — ideal for gutters and detailed surfaces.
- Sandwich panel roof upgrades
- Renewing the seal at fixings, laps, rooflights and ridges.
- Chemical-resistant coatings
- Epoxy and specialist systems for acid and wastewater basins and industrial floors.
Industrial waterproofing: application stages
Site survey and risk assessment
Roofs, gutters and floors are inspected; production areas, access, work at height and fire risks are assessed.
Technical design
Wind load and fixing pattern, insulation and drainage capacity are calculated to select the system.
Phasing and programme
Work is zoned so production is not disrupted and planned around shifts and deliveries.
Preparation and temporary protection
The existing finish is evaluated and opened areas are closed against rain at the end of each day.
Waterproofing installation
The membrane or spray system is installed with all seams and details.
Testing, reporting and maintenance plan
Welds and seams are checked; an application report and maintenance recommendations are handed over.
Industrial waterproofing: key benefits
Production continuity
Removes the risk of leak-related downtime and damage to products and machinery.
Lightweight, fast systems
Large roofs completed quickly without adding structural load.
Energy efficiency
Roofs designed together with insulation reduce HVAC costs.
Longer maintenance intervals
UV- and weather-resistant membranes need less intervention.
Safety-led site management
Work-at-height and hot-work permits are planned upfront.
Industrial waterproofing: frequently asked questions
Which system is used on industrial roofs?
Large roofs mostly use mechanically fixed PVC or TPO membranes over insulation. Polyurea and liquid polyurethane are preferred for detailed areas, gutters and fast application.
Can the roof be waterproofed while production continues?
Yes. We zone the work, never leave areas open overnight and plan around shifts and deliveries.
How are sandwich panel roof leaks fixed?
Leaks usually come from fixings, laps and gutter junctions. We assess local repair of these points or overlaying the whole roof with a membrane or liquid system.
PVC or TPO membrane?
Both are long-lasting single-ply membranes. Chemical exposure, fire requirements, detail density and budget decide; we recommend after the survey.
How is the cost of industrial waterproofing determined?
By roof or floor area, condition of the existing finish, insulation needs, number of details, access and safety requirements.
How often should a factory roof be maintained?
We recommend gutter cleaning and a visual inspection at least once, ideally twice a year (autumn and spring).
