Common problems
- Moisture under tiling
- Loose tiles
- Leaking joints and bilges
- Frost damage outside
- Insufficient connection at doors and drains
WD-04 · WATERPROOFING PER BUILDING PARTPolyShield Waterproofing
Waterproofing under tiling for business projects
The tile is the finishing touch; the membrane underneath forms the watertight security.
Technical context
First recognize the building part and the load.
A sustainable tile structure starts with a slope, stable details and continuous waterproofing. PolyShield coordinates membrane, adhesive layer, joints and connections as one structure.
Problem · cause · solution
From visible defect to substantiated system route.
Possible causes
- Tiles are considered a primary flood barrier
- Movement not continued
- Insufficient slope
- Incompatible adhesive or membrane layers
- Details without curb or reinforcement
Complete system choice
Substrate, primer, details, membrane, protection and evidence are recorded as one project-specific structure.

What the right waterproofing protects or saves.
Hidden security
The flood defense remains protected against direct traffic and weather loads.
Complex shapes
Kimmers, drains and connections are incorporated seamlessly.
Complete coordination
Waterproofing and tile construction are not treated as separate disciplines.
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-W06 · PRIMARY
Under 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
- Mineral slope layer
- Sufficient construction height available
- Respect movement joints in the entire structure
- Tile adhesive and membrane demonstrably compatible
- Check membrane before covering
- 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
Detailed plan
Slopes, curbs, joints and drains are determined in advance.
- 02
Substrate
Cracks and weak areas are repaired and primed.
- 03
Membrane control
The waterproofing is applied and inspected before covering.
- 04
Tile construction
Adhesive layer, tiles and joints correspond to the approved route.
Frequently asked questions
For a targeted first project decision.
Can waterproofing be done over existing tiles?
Only after a project-specific assessment. Removal is often necessary to reliably assess the substrate, slope and damage.
