A system applied on the wrong side or on moving, inadequately prepared concrete combats the visible effect but not the technical cause.
NEW BUILD / BELOW GRADE
The water side and concrete condition determine the route.
Underground waterproofing doesn't start with a coating name. The direction of water pressure, crack movement, concrete quality, accessibility and ventilation determine whether a mineral, crystalline, injection-assisted or zero-VOC 2K construction makes sense.Activities
Cellars and lift wells as a complete system scope.

- Larger basement walls and floors
- Lift wells within apartment buildings
- Technical wells
- Foundation surfaces
- Underground parking facilities
The technique must be clear before implementation.
- Negative water pressure behind the layer
- Active cracks and leaking seams
- Insufficient adhesion to young or contaminated concrete
- Unsafe emissions in confined space
- Restore after installations have been installed
Wij starten met oorzaak, waterzijde en betonconditie en selecteren vervolgens een aantoonbare aanpak. Actieve injectie en zwaar herstel worden waar nodig met partners georganiseerd.
Project value
What the complete system delivers.
- 01Technology suitable for water pressure
- 02Low- or zero-VOC route possible
- 03Early control before installations
- 04Relationship between repair and waterproofing
- 05No general product claim without proof
Four manageable phases.
Cause and water side
Groundwater, construction moisture, leaking joint or crack are technically distinguished from each other.
Concrete and repair
Hollow zones, gravel nests, cracks and bilges are included in a recovery and detailed plan.
Approach
Mineral, crystalline or 2K membrane technology depends on pressure direction, moisture and use.
Control and protection
The layer is checked before installations, walls or finishing restrict access.
Release criteria
When the system can — and cannot yet — start.
Constructive movement
Working cracks and seams must first be assessed structurally.
Active water
Ongoing leakage may require an injection or temporary water stop before surface sealing is possible.
Confined space
Ventilation, emissions and safe processing are part of the system choice.
QUALITY FILEDon't just apply.
Don't just apply.
Also deliver demonstrably.
- ✓ Water and cause hypothesis
- ✓ Concrete and detail inventory
- ✓ Voorlopige aanpak
- ✓ Partner demarcation for injection or recovery
- ✓ Inspection and delivery file
Information for every decision maker.
Main contractor
Early clarity before installations and finishing close the construction.
Constructor or consultant
Clear boundary between structural repair and waterproofing system.
Building owner
A solution based on cause and accessibility, not just the visible moisture.
Technical questions
Frequently asked questions.
Is waterproofing possible on the inside?+
Soms wel, maar negatieve waterdruk stelt andere eisen dan afdichting aan de waterzijde. Dit moet per project worden beoordeeld.
Do you carry out injection work yourself?+
Injection work can be organized as a specialist partner scope when required within a larger waterproofing job.
Is a coating sufficient for a structural crack?+
No. Structural or working cracks first require an assessment and an appropriate detailed or repair plan.
Beoordeling in de praktijk
Wat moet bij kelders en liftputten vóór uitvoering duidelijk zijn?
Underground waterproofing doesn't start with a coating name. The direction of water pressure, crack movement, concrete quality, accessibility and ventilation determine whether a mineral, crystalline, injection-assisted or zero-VOC 2K construction makes sense.

Wat we eerst willen weten
- Water and cause hypothesis
- Concrete and detail inventory
- Voorlopige aanpak
- Partner demarcation for injection or recovery
- Inspection and delivery file
Wanneer we een andere aanpak adviseren
Negatieve waterdruk achter de laag Actieve scheuren en lekkende naden Onvoldoende hechting op jong of vervuild beton Onveilige emissie in besloten ruimte Herstel nadat installaties zijn geplaatst
