Waterproofing system for concrete roofs
Waterproofing system for concrete roofs as a complete waterproofing route for concrete roof slabs and technical roofs.
- Inspect roof structure, moisture and details
- Cleaning and repairing weak areas
- Apply primer and detail reinforcement
- Waterproof membrane delivered in a controlled manner
From damage picture to solution
Problem, cause and effect first visible.
- UV and weather loads
- Movement of seams and connections
- Overdue maintenance or previous emergency repairs
Moisture can damage insulation, interior, installations and business processes.
Een renovatie afgestemd op het gebouw van ondergrond, details, primer en doorlopend membraan.
Business benefits
The value is not just in the new layer.
Lifespan
Maintain a technically suitable roof structure and postpone replacement.
Continuity
Organize renovation per work area around the use of the building.
Risk management
Include critical details before consequential damage occurs.
Maintenance
Een inspecteerbare en lokaal herstelbare aanpak creëren.
RISK OF DELAY
Delay can allow local defects to progress to wet insulation, larger repair zones and damage under the roof.
First have the size, cause, accessibility and desired planning assessed. We then compare repair, renovation and, where necessary, replacement without selling a standard solution in advance.

System profile
What this direction is rated for.
- Concrete roof slabs
- Technical roofs
- Cement-bound slope layers
- Walkable inspection areas
- Crack bridging system
- High adhesion
- UV-resistant variant
- Resistant to high water loads
- Concrete
- Cement screed
Application boundaries
Where this system fits primarily, conditionally or non-standard.
The classification helps with the initial selection. Substrate, load, detailing and current system documentation remain decisive.
- Wet or unstable surface
- Unknown layers without test adhesion
- Structural defect without repair
- Undocumented product combination

Wat we eerst willen weten
- Tensile strength
- Residual moisture
- Cracks and joints
- Pores and gravel nests
- Slope
Wanneer we een andere aanpak adviseren
Constructieve scheuren laten beoordelen Onvoldoende sterk beton eerst herstellen Negatieve waterdruk apart behandelen
01 / Inspect
We want to know this first.
- Tensile strength
- Residual moisture
- Cracks and joints
- Pores and gravel nests
- Slope
02 / Limit
When we don't execute immediately.
- Have structural cracks assessed
- Repair insufficiently strong concrete first
- Treat negative water pressure separately
03 / Substantiate
Which must be demonstrable.
- Measurably record substrate strength and moisture
- Scheurdetails per project tekenen
- Classification by system variant
Technical proof
Performance is system and structure specific.
The statuses below are deliberately reserved. A proof is only shown as proven after the current document, the system variant and the intended use have been checked.
ETA/EAD
An ETA applies to the described system kit and its intended use. Document number and current system variant are checked before publication.
CE and declaration of performance
CE and DoP describe declared product performance; they are not a blanket endorsement of every roofing project.
BROOF classification
Only claimable for the exact tested roof structure, substrate, layer thickness and the stated test suffix, for example BROOF(t1).
Waterproofing
Test performance and application conditions must correspond to the selected membrane variant and project structure.
Crack bridging and movement
Class, temperature and layer thickness are taken from the current technical documentation.
VOC and environmental documentation
VOC, EPD and other environmental claims are only published with a current, traceable source.
Van mogelijke oplossing naar aanbieding
Four pieces of information that really determine the quotation.
Material, condition, moisture, adhesion and existing layers.
Edges, bilges, drains, penetrations, seams and connections.
Water, UV, movement, traffic, use and operating conditions.
Accessibility, phasing, safety, planning and weather window.
Frequently asked questions
Technical clarity before application.
Is this system directly suitable for every surface mentioned?
No. The substrate must fall within the approved system scope and is checked for cohesion, moisture, contamination, movement and adhesion. The correct preparation and primer are then recorded.
Is the layer structure shown always the same?
The functions remain recognizable, but primer, reinforcement, number of layers and consumption may differ per substrate and load. The final structure is stated in the project specification.
Can the system be installed over existing waterproofing?
Only when material, mounting and condition are known and a compatible structure can be demonstrated. For unknown membranes or coatings, we first carry out identification and test adhesion.
What lifespan or warranty applies?
Technical ratings and expected useful lives are for specifically rated systems. The project guarantee also depends on the surface, scope, implementation, maintenance and written agreements.
What is the first step?
A project screening and inspection. We record construction, surface, damage picture, water load, details, accessibility and desired planning.
