Common problems
- Leakage under green package that is difficult to remove
- Root penetration
- Damage during installation
- Clogged drains
- No check before hedging
WD-07 · WATERPROOFING PER BUILDING PARTPolyShield Waterproofing
Build green roofs and roof gardens reliably waterproof
A demonstrably waterproof membrane before protection, drainage and greenery hide it from view.
Technical context
First recognize the building part and the load.
After installation, the waterproofing under a green roof is difficult to access. That is why root resistance, details, compartmentalization, drainage and control before covering are central.
Problem · cause · solution
From visible defect to substantiated system route.
Possible causes
- Non-root resistant membrane
- Insufficient protective layer
- Sharp load or work
- Details without inspection zone
- Drainage and emergency overflow insufficient
Complete system choice
Substrate, primer, details, membrane, protection and evidence are recorded as one project-specific structure.

What the right waterproofing protects or saves.
Manage risk before hedging
Details and membrane are inspected when repair is still practical.
Seamless geometry
Curbs, planters and complex shapes can be continuously sealed.
Coordinated roof construction
Waterproofing, protection, drainage and greenery are not designed separately.
System selection
Primarily promising, then technically confirmed.
The maps show a system direction. The final variant results from inspection, test adhesion and current technical documentation.
PS-W08 · PRIMARY
Green roofs
Hidden waterproofing structure under greenery and soil packages, where root resistance, detailing and inspectability must be demonstrable.
Open technical system route ↗PS-W01 · CONDITIONAL2K polyurea waterproofing
Complete cold-applied two-component system for seamless waterproofing of technically suitable commercial roofs and structures. From surface control and primer to reinforced details and a white, UV-resistant waterproof final layer.
View conditions ↗PS-W03 · CONDITIONALConcrete roofs
Elastic waterproofing for mineral roof substrates, with repair of pores, cracks and transitions before membrane application.
View conditions ↗- Concrete
- Technically suitable bituminous roof structure
- Root resistance demonstrable per system variant
- Completely check waterproofing before covering
- Coordinate protective and drainage layer
- Keep drains accessible and inspectable
- Enclose wet or insufficiently load-bearing surfaces
- Unknown layers without compatibility check
- Only cover structural defects with coating
- Performance claims without appropriate system documentation
From recording to delivery
Four steps that make the system controllable.
- 01
Roof and green design
Load, drainage, elevations and green package are assessed in combination.
- 02
Root resistant system
Only demonstrably suitable materials and details are specified.
- 03
Control
The membrane is completely checked and recorded before covering.
- 04
Protection
Protective layer, drainage and substrate are applied in a controlled manner.
Frequently asked questions
For a targeted first project decision.
Is every liquid waterproofing root resistant?
No. Root resistance must be demonstrable for the chosen system variant.
