The technical task
The scale of the roof and the number of skylights require a planned implementation with attention to long details and logistics.

Waterproofing large commercial roof
Uithoorn, Netherlands · White liquid membrane
Project image
Which is demonstrable in this project.
A large commercial roof with multiple skylights, installations and long connections, provided with continuous white waterproofing.
The content is based on available implementation information and project images. For a new object, the surface, load, details and system choice are always determined project-specifically.ObjectLarge commercial roof

01 / Before renovationDIGITAL PROJECT MODELTechnical demarcation
On large roofs, logistics and detail repetition are just as important as the choice of materials.
Long roof edges, multiple skylights and installations make a manageable work compartment layout necessary. This way, preparation, weather conditions, details and final inspection can be monitored per zone without losing the coherence of the entire system.
The system-oriented method
- 01Divide the roof into controllable work zones
- 02Detail skylights, roof edges and installations in advance
- 03Monitor application and weather conditions per zone
- 04Visually check end surface and connections
The visible result
A coherent white roof surface in which the main surface and complex connections are treated as one waterproof system.
Decision factors
Why this scope made technical sense.
A system name alone does not explain project choice. The existing condition, risks, details and feasibility together determine the renovation strategy.
Project decision
- Large and repetitive roof surface
- Many long connections around skylights
- Work schedule around building use
- Light, UV-resistant final finish
Included in the scope
- Division into controllable work zones
- Pre-treatment of selected roof parts
- Detailing of edges, skylights and installations
- Continuous white final layer per cleared zone
Technically assessed
- Accessibility and safe material routing
- Dryness and adhesion per work area
- Connection sequence around long details
- Transitions between individual execution phases
Project images
Visible evidence, without filling in missing data.
A complete public work phase file is not yet available for this project. Therefore, we only show confirmed images of the implemented system and explicitly identify missing data.
Quality & evidence limit
What has been checked, confirmed and deliberately not generalized?
Quality moments
- Only release the work area after the surface has been checked
- Perform details before closing the main plane
- Monitor application conditions per zone
- Visual delivery check including phase transitions
Confirmed project information
- The large white roof surface has been photographically captured
- Skylights and installations are visibly included in the system
- Long eaves show a continuous connection
Project-specific boundaries
- Exact project area has not yet been publicly verified
- Public images are not a substitute for layer thickness or adhesion reporting
- Performance does not automatically apply to another roof without inspection
Technical project passport
System variant, substrate, primer, batch data, consumption, application conditions, ETA/DoP, applicable BROOF build-up and maintenance are only included when confirmed project-specifically.

Een projectdossier moet meer laten zien dan alleen het eindresultaat.
PolyShield bouwt projectbewijs op rond zes vaste onderdelen: uitgangssituatie, technische keuze, systeemopbouw, uitvoering, kwaliteitscontrole en oplevering. Zo blijft zichtbaar wat daadwerkelijk is uitgevoerd en welke gegevens projectspecifiek zijn.
