Good drainage starts below the surface. Whether you're tackling a backyard landscaping project, building a rooftop garden or working on a large commercial development, managing excess water is an important part of getting the job done right.
Eco Sustainable House supplies Atlantis Drainage Cells, also known as Flo Cells, in 20mm, 30mm and 50mm options. Designed for a range of subsurface drainage applications, these lightweight, modular systems help create a drainage layer beneath landscaped and constructed surfaces.
From homeowners and DIY renovators to landscapers, builders and commercial contractors, there's a drainage solution to suit projects big and small.
What Are Atlantis Drainage Cells?
Atlantis Drainage Cells are modular plastic drainage units installed beneath surfaces to create a void through which excess water can flow towards designated drainage outlets.
Rather than allowing water to accumulate beneath landscaping or constructed areas, drainage cells help establish a pathway for water movement while providing a structured drainage layer.
Their lightweight design makes them practical to handle and install across a variety of applications, including residential landscaping, commercial developments and architectural projects.
Available in 20mm, 30mm and 50mm options, Atlantis Drainage Cells offer flexibility when selecting a drainage solution to suit your project's requirements.

Where Can You Use Atlantis Drainage Cells?
One of the key benefits of drainage cells is their versatility. They can be incorporated into a range of landscaping, building and infrastructure projects where subsurface drainage is required.
1. Planter Boxes and Garden Beds
Planter boxes and raised garden beds need appropriate drainage to help manage excess water around plant roots. Drainage cells can create a drainage layer beneath the growing medium, helping water move towards designated outlets.
2. Roof Gardens and Green Roofs
Roof gardens and green roofs require carefully designed drainage systems to manage water within the landscaping assembly. Drainage cells can provide a drainage layer beneath the growing medium, helping manage excess water as part of the overall roof design.
3. Podium Landscaping
Landscaped podiums and elevated outdoor spaces often incorporate multiple layers, including waterproofing, drainage and growing media. Drainage cells can form part of these assemblies, helping direct excess water towards the designed drainage points.
4. Retaining Walls and Vertical Drainage
Managing water behind retaining walls is an important consideration in many construction projects. Suitable drainage systems can help direct water away from the wall structure and reduce the buildup of hydrostatic pressure. Drainage cells may be incorporated into appropriate designs where their configuration and installation requirements suit the application.
5. Sports Fields and Landscaped Areas
Landscaped areas and sports facilities can require subsurface drainage to help manage excess water beneath the finished surface. Drainage cells may be suitable for selected applications, depending on the required drainage capacity, loading and overall system design.
6. Basements and Underground Applications
Underground structures may require drainage systems to manage groundwater and water infiltration. Drainage cells can be used in suitable applications as part of a broader system designed around the site's waterproofing, drainage and structural requirements.
Every project is different, so it's important to select the appropriate product and installation method for the intended application.
Choosing the Right Drainage Cell Thickness
Atlantis Drainage Cells are available in three thickness options: 20mm, 30mm and 50mm.
The most suitable option depends on factors such as the available installation depth, required drainage capacity, loading conditions and the design of the surrounding system.
-
20mm Drainage Cells: A low profile option for applications where installation depth is limited and the product is suitable for the intended drainage requirements.
-
30mm Drainage Cells: An intermediate depth option for suitable landscaping and building applications.
-
50mm Drainage Cells: A deeper option where additional void space may be required, subject to the project's drainage and structural specifications.
These are general considerations rather than fixed application rules. Always check the relevant product specifications and project requirements before selecting a drainage cell.

Don't Forget the Geofabric
Drainage cells are often used alongside geofabric, also known as geotextile filter fabric, to help manage soil and sediment within a drainage system.
When specified and installed correctly, geofabric allows water to pass through while helping prevent surrounding soil and particles from entering the drainage layer. This can help maintain the intended function of the system.
The correct fabric type and placement will depend on the application, soil conditions and drainage design.
If you're planning a landscaping or construction project, it's worth considering the drainage cell and filter fabric requirements together.

Need a Solution for Grass or Gravel? Explore Turf Cell and Gravel Cell
If your project involves a grassed driveway, gravel parking area or ground that needs additional surface stability, Eco Sustainable House also supplies 50mm turf and gravel cell systems.
While drainage cells are generally used to create a subsurface drainage layer, turf and gravel cells are designed to help stabilise the ground surface. Choosing the right product depends on what you're trying to achieve.
Turf Cell for Grassed Driveways and Parking Areas
Turf Cell 50mm is designed to reinforce grassed surfaces while helping maintain a stable, permeable ground surface in suitable applications.
It may be suitable for projects such as grassed driveways, overflow parking and selected areas used for parking cars, caravans, trailers or boats, provided the system is appropriate for the expected loads and site conditions.
Gravel Cell for Firmer Gravel Surfaces
Gravel Cell 50mm is designed to help contain and stabilise gravel, reducing movement and creating a more consistent surface.
It's worth considering for suitable driveways, pathways, parking areas and other gravel-surfaced projects where improved ground stability is needed.

Managing Larger Volumes of Stormwater? Consider Atlantis Flo Tanks
For projects that require more comprehensive underground stormwater management, Eco Sustainable House also supplies Atlantis Flo Tanks.
Depending on the selected system and site design, underground stormwater tanks can be incorporated into detention, infiltration and rainwater harvesting applications.
These systems serve a different purpose from drainage cells, making them worth considering when your project requires a broader stormwater management solution.
The right approach will depend on the site, expected water volumes, soil conditions and relevant engineering requirements.
