This 4.5kg Concrete Ballast Tile is a compatible alternative ballast tile for use with ValkPro+ flat roof mounting systems, weighting down the mass carriers that anchor a non-penetrating flat-roof PV array in place. Measuring 300 × 150 × 45mm, the smaller footprint of this tile makes it useful for fine-tuning ballast distribution alongside the larger 9kg tile.
Ballasted flat-roof systems rely on tile weight rather than roof penetration to resist wind uplift, so the exact number and layout of ballast tiles required is project-specific — always confirmed by a full system design and structural report rather than estimated on site.

System Compatibility
Compatible Alternative — Not a Genuine Van der Valk Part
This is a compatible alternative ballast tile for use with ValkPro+ flat roof mounting systems, matching the weight and dimensions of the standard tile. It is not a genuine Van der Valk-branded component, but is confirmed suitable for use with the ValkPro+ mass carrier system.
Full System Design Required Before Installation
The exact quantity of ballast tiles required, and how they should be distributed across the array, depends on roof height, wind zone, and array layout. A full ValkPro+ system design and structural report is required to confirm the correct ballast specification before installation.
Key Features
Non-Penetrating Ballast Solution
Weighs down the array's mass carriers to resist wind uplift, avoiding the need to penetrate the roof membrane.
Compatible With ValkPro+ Systems
Sized and weighted to work as a compatible alternative within ValkPro+ flat roof mounting layouts.
Compact Footprint for Fine-Tuning Ballast
The smaller 300 × 150 × 45mm footprint makes this tile useful for adjusting ballast weight precisely once the main 9kg tiles are in place.
Durable Concrete Construction
Manufactured from solid concrete for long-term outdoor durability and consistent, reliable ballast weight.
Suits South-Facing and East-West Layouts
Ballasted flat-roof systems of this type are typically specified for both south-facing and east-west array configurations.
Works Alongside the 9kg Ballast Tile
Designed to be used together with the matching 9kg ballast tile to achieve the correct total ballast weight and improve weight distribution across the array.

Frequently Asked Questions
Is this a genuine Van der Valk ballast tile?
No. This is a compatible alternative ballast tile matching the weight and dimensions used within ValkPro+ flat roof mounting systems, rather than a genuine Van der Valk branded component.
What's the difference between this tile and the 9kg tile?
This 4.5kg tile has a smaller footprint (300 × 150 × 45mm) than the larger 9kg tile, and is typically used to fine-tune the total ballast weight and distribution once the main tiles are in place.
How many of these tiles do I need for my installation?
The exact quantity and layout is project-specific, depending on roof height, wind zone, and array configuration. A full ValkPro+ system design and structural report is required to confirm the correct specification.
Does this tile require roof penetration to fit?
No. It is part of a non-penetrating ballast system, using weight alone to resist wind uplift rather than fixing through the roof membrane.
Can this tile be used on its own, without the 9kg tile?
It can be used independently, but is most commonly specified alongside the 9kg tile as part of a full ballast layout confirmed by the system design report.
