Frequently asked questions
How is this drainage cell installed beneath a green roof?
Install the drainage cell directly over the waterproofing membrane. Overlay with a filter fabric, then add soil or growing media. Ensure drainage outlets are correctly configured.
What load can this drainage cell handle?
This drainage cell handles loads up to 70 tonnes per square metre (70 t/m²). This compressive strength supports foot traffic, planter boxes, and other structural loads on podiums or landscaped decks.
Is this product compatible with waterproofing membranes?
Yes, the HexCell is compatible with most waterproofing systems. A separation layer, such as a geotextile, is recommended to protect the membrane from potential damage during installation and service.
Can this drainage cell be used under heavy vehicle traffic?
No, this drainage cell is not rated for high vehicular traffic without specific additional structural support. Its design is for pedestrian and landscaped loads.
How should off-cuts be disposed of?
Off-cuts are recyclable. Dispose of them according to local plastic recycling regulations. Avoid landfill or burning.
Applications and benefits
| Application | Key benefit | Primary trades |
|---|---|---|
| Green roof and podium landscape drainage | Prevents hydrostatic pressure buildup, protects waterproofing membranes, supports structural loads up to 70 t/m². | Landscapers, Waterproofers, Builders |
| Retaining wall backfill drainage solutions | Creates a continuous drainage void behind walls, reducing lateral pressure. Chemically resistant to soil-borne elements. | Civil Contractors, Landscapers, Waterproofers |
| Balcony and planter box voiding and runoff control | Manages excess water efficiently with 14,400 L/h/m² drainage capacity. Lightweight, reducing structural load. | Builders, Landscapers, Waterproofers |
| Sports field and civil engineering sub-surface drainage | Delivers rapid sub-surface water removal, maintaining consistent ground stability. Durable against environmental factors. | Civil Contractors, Sports Ground Specialists |
How to apply 30mm HexCell Drainage Cell - Standard Duty 550:
- Prepare substrate ensuring level surface and proper fall
- Lay waterproofing membrane and protective geotextile
- Install drainage cell panels by interlocking edges
- Trim to fit using utility knife where needed
- Cover with filter fabric, then backfill with soil or overlay
Product limitations
- Not for: High vehicular traffic without additional structural support. The 70 t/m² compressive strength is suitable for pedestrian and landscaped loads.
- Requires: A stable, level substrate for effective installation and uniform load distribution.
- Cannot be: Used as a primary waterproofing layer. This product is a drainage component, not a barrier.
Safety and handling
Personal protective equipment
Wear safety gloves and steel-capped boots during handling and installation.
Handling
Exercise caution when using sharp tools for trimming panels. Avoid forcing mismatched sections to prevent damage to the panels or injury.
Storage and disposal
Store panels away from open flames or extreme heat sources. Off-cuts are recyclable; dispose of in accordance with local regulations.
Substrate guide
Proper substrate preparation is critical for the long-term performance and stability of the drainage cell system. Ensure surfaces are stable, clean, and correctly prepared.
Concrete slabs
Surface prep: Ensure the concrete slab is level and free from debris, sharp protrusions, or loose material that could impede installation or damage underlying layers.
Primer: Not required. The drainage cell sits as a layer above the concrete.
Bituminous waterproofing membranes
Surface prep: Verify the membrane is fully cured, clean, and undamaged. A protective geotextile layer should be placed directly over the membrane before the drainage cell.
Primer: Not required for the drainage cell directly. A separation layer is essential.
Compacted sand beds
Surface prep: Ensure the sand bed is uniformly compacted and graded to the specified fall. Remove any large aggregates or foreign objects.
Primer: Not required. The drainage cell can be placed directly on the prepared sand bed in landscaping applications.
