Common problems
- Leakage to underlying spaces
- Cracks and open connections
- Loosening tiles or coating
- Slippery in rain
- Concrete damage to edges and bottom
WD-03 · WATERPROOFING PER BUILDING PARTPolyShield Waterproofing
Make balconies and galleries permanently waterproof
Protect the supporting structure before moisture leads to concrete and consequential damage.
Technical context
First recognize the building part and the load.
Balconies and galleries combine waterproofing, safe use and appearance. The right route connects crack treatment, details, slope, membrane and a wear-resistant non-slip finish.
Problem · cause · solution
From visible defect to substantiated system route.
Possible causes
- Water penetration through joints and cracks
- Insufficient slope
- Movement at facade and sill connections
- Freeze-thaw load
- Outdated or missing waterproofing
Complete system choice
Substrate, primer, details, membrane, protection and evidence are recorded as one project-specific structure.

What the right waterproofing protects or saves.
Prevents consequential damage
Early waterproofing limits damage to concrete, reinforcement, facades and underlying spaces.
Safe usage layer
Texture and anti-slip are tailored to rain, foot traffic and maintenance.
One continuous finish
Complex edges, curbs and drains can be integrated seamlessly.
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-W07 · PRIMARY
Walkable roofs
Waterproofing with additional wear-resistant and anti-slip structure for maintenance routes and regularly used roof areas.
Open technical system route ↗PS-W06 · PRIMARYUnder tiles
Protected liquid membrane under a suitable tile structure for terraces and roof surfaces where the waterproofing is not directly exposed.
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
- Cement screed
- Technically suitable existing coating
- Tile build-up after removal or project assessment
- Assess structural cracks separately
- Slope and drain must function
- Work out sills and facade details in advance
- Adjust friction to use and cleaning
- 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
Damage picture
Cracks, hollow areas, slopes and connections are recorded.
- 02
Concrete repair
Insufficient load-bearing or corroded zones are repaired first.
- 03
Waterproofing
Details and membrane are applied as a continuous layer.
- 04
Utility finish
Wearing layer, color and roughness are tailored to the situation.
Frequently asked questions
For a targeted first project decision.
Is tiling itself waterproof?
No. Grout and tiles do not provide reliable primary waterproofing; below this a matched membrane is needed.
Can a balcony be constructed in parts?
This is sometimes possible, provided that seams, phasing, residents' routes and weather protection are technically worked out in advance.
