Waterproof system for walkable roofs
Waterproof system for walkable roofs as a complete waterproofing route for maintenance routes and technical installations.
- 01Inspect roof structure, moisture and details
- 02Cleaning and repairing weak areas
- 03Apply primer and detail reinforcement
- 04Waterproof 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.
A project-specific renovation of the substrate, details, primer and continuous membrane.
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
Create an inspectable and locally recoverable system route.
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.

01 / Location confidentialPlanned roof renovation of school buildingApproximately 700 m² of outdated bituminous roofing with strong crackle formation, systematically renovated with primer, reinforced details and two layers of white 2K polyurea.

02 / MiddelburgEmergency repair of production roof with 2K polyureaApproximately 150 m² of a commercial roof with multiple leaks has been purposefully renovated. The urgent system approach protects the valuable production equipment under the roof against further water damage.

03 / THE HAGUELocal 2K polyurea roof renovationOp een bedrijfsdak van circa 350 m² zijn meerdere lekkages doelgericht verholpen. De geselecteerde zones zijn gereinigd en vervolgens met primer, geotextiel en een vloeibare 2K-waterdichting behandeld.

A complete structure, no loose coating.
The structure shown makes the function of each layer understandable. Primer, reinforcement and consumption are only definitively specified after subsurface research.

System profile
What this direction is rated for.
- Maintenance routes
- Technical installations
- Roof terraces with controlled use
- Roof parking after separate engineering
- High mechanical resistance
- Non-slip possible
- UV stable finish
- Quickly loadable variants
- Concrete
- Metal
- Existing membrane
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.
Other building parts only after additional validation.
- Wet or unstable surface
- Unknown layers without test adhesion
- Structural defect without repair
- Undocumented product combination
01 / Inspect
We want to know this first.
- Traffic intensity
- Point tax
- Non-slip
- Drainage
- Transitions
02 / Limit
When we don't execute immediately.
- Design vehicle traffic separately
- Coordinate anti-slip with cleaning
- Do not use before complete curing
03 / Substantiate
Which must be demonstrable.
- Determine tax class
- Document wear resistance and roughness
- Determine release time in writing
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.
From system direction to offering
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.
