PS-PUA-05 / Engineered System
PolyShield Concealed Deck
Covered waterproofing under tiles and terrace structuresAn elastic 2K waterproofing system that is inspected and documented before it is covered.
What this system was developed for
A clear project role, not a universal coating.
Balconies and terraces
Under tiling
Stage decks
Wet outdoor areas
Concrete
Cement screed
Suitable repair mortar
Waterproofing designed separately from visible finish
Fast membrane route possible
Details visible before covering
Suitable for renovation and new construction
When is this route promising?
When waterproofing under tiles or a terrace finish, tiles and joints do not form the primary water barrier. The 2K membrane, slope, details, adhesive layer and movement joints must be designed as one compatible structure
PS-PUA-05 / interactive system build-up
See what every system layer does.
Separate the layers, select a function and see which control point and project evidence belong to the next work phase. This visual is a technical selection framework, not a universal installation detail.
Complete system construction
Each layer has one controllable function.
The structure shown is a selection frame. Primer, layer thickness, consumption and details are only finalized after inspection, test surface and document check.

Project evidence under construction
This system family is only linked to a reference when the scope and implementation are demonstrable.
Until then, we will not show a generic or borrowed project claim. Share your project situation for a project-specific assessment.
Have a project assessed ↗Frequently asked technical questions
Short answer, clear line of evidence.
Aren't tiles and grout already waterproof?+
No. They form a utility finish; the reliable primary waterproofing is in the designed membrane layer below.
Can the finish be placed immediately after application?+
Only after the prescribed curing, checking and release of the selected structure.
Are dilations simply overcoated?+
No. Structural joints must be able to continue to absorb their movement in the complete structure.

DetailsWhen detail reinforcement is needed
Geotextiles strengthen selected transitions, but do not replace a structural joint or damage assessment.

AttachmentWhy a primer is not an afterthought
The primer function depends on the substrate, porosity, moisture and the chosen membrane technology.
