City life is always a tug of war between concreted jungles and our desire to have green breathing space. And as our cities continue to expand both vertically and horizontally, we are also made to think smarter, how do we integrate nature into built features without jeopardizing the safety of the structure?
At this point, drainage cells come in not only as a technical solution but as a manifestation of eco-smart living. Though the majority of people could walk over green rooftops or even walk past vertical gardens without paying much attention to them, deep in the bowels is an unsung hero: the drainage cell system.
From small-time Drain cell manufacturers in India to environmentalists looking to build more eco-friendly cities, this small invention is transforming the way cities breathe. However, how do they operate? Why are they termed sustainable? Shall we get down to some details-pun intended.
What Are Drainage Cells?
If it is the first time that you are hearing the term drainage cell, then you might think that the cell is described in a plumbing manual.
However, it turns out to be very easy. Drainage cells are lightweight, modular plastic systems (commonly of polypropylene or recycled plastic), used to create a sub-surface plane under landscaped surfaces. Their purpose? Just to make the water flow freely so as to cover the soil or other layers that are supporting the structure.
Imagine them as Lego-like tiles under the roof garden or under synthetic lawns. They form an air gap where water can drain fast, which avoids waterlogging and destroying the structure. What is more, thanks to the Drainage cell manufacturers, such systems can now be found in green buildings, as well as podium gardens, terraces and even sports fields.
Real-Life Story: A Green Terrace Saved by Drainage Cells
One of my closest friends was also an architect who, in 2022, was modifying an old bungalow in Pune. The owner wanted his terrace to be green like ivy, but the building is old and has experienced past problems with water leakages. Soil installation could not simply be put in place- waterproofing would not help either.
So they went to one of the famous manufacturers of the drainage cells in India, and they decided to buy multilayers: waterproof membrane, drainage cells, filter fabric, and soil above.
The result? The roof was turned into a mini paradise- with flowering and vegetables and even a bench space. Two monsoons passed now there is no leakage, no pooling of water. Nothing but fresh basil, tomatoes, and an extremely contented family.
How Do Drainage Cells Work?
On the surface, one may feel that drainage cells are mere plastic tiles. Yet internally, they are genius.=
The cells generate a hole under the turf or soil, and the water can flow horizontally on the surface. This assists in spreading surplus water to the immediate drainage or drain pipes. They are light in comparison with the standard gravel drainage systems, installable, and characterised by increased flow rates.
They are also stratified. Normally, the geotextile will be laid on the drainage cell in order to ensure that the soil does not block the channels. And depending on the structure there is also commonly a water proofing membrane below.
They are also powerful as they have an enormous compressive strength; they can support the weight of soil, furniture, or even a car in green driveways or rooftop gardens.
Why Do Urban Landscapes Need Them?
Cities are space limited, and the land is predominantly made of concrete. This will hardly allow any percolation of surface water into the ground.
Here, drainage cells come into their own. And when applied with green roofs, podium gardens, or even vertical gardens, they:
- Prevent waterlogging
- Lessen building hydrostatic pressure
- Enhance aeration in plants at the root level
- Encourage stormwater harvesting systems
What is more, they can be custom-covered, as their modular construction enables covering limitless spaces, i.e., a big shopping mall roof, as well as a small balcony with a garden.
What Are Drainage Cells Used For?
Here is a rundown of where drainage cells are having a huge difference:
- Environmentally friendly roofs and terrace gardens
- Commercial landscape kinds: Podium landscaping
- Planter boxes and raised beds
- Parking decks and driveways
- Vertical gardens and green walls
- Sport grounds and golf courses
- Drainage of retaining walls
An increasing number of contemporary urban housing developers in cities such as Bangalore, Hyderabad, and Mumbai are currently installing the drainage cell systems when manifesting their green buildings in their itineraries as early as possible. Why? The reason is that they spread the cost of maintenance over an extended period and make buildings obtain the IGBC or LEED certification.
What About Pricing? Are They Expensive?
The Drainage cell price may be different according to the quality and thickness and supplier. At average rates, in India, the price tends to vary between 60 and 150/sq—foot (including materials and simple installation charges).
Yes, on the surface, it may appear costly as compared to the plain soil or gravel. However, we must think long-term.
Drainage cell equal smooth water flow means healthier plants, dry interiors, and zero headache in the future.
So as to me? It is an investment, not a cost.
Conclusion
The situation is like the one in the war between concrete and nature, where drainage cells may appear just a grain of sand. However, they do not play an insignificant role.
Want to install drainage cells? Contact certified drainage cell manufacturers in India. Ask questions about durability, drainage rates and yes, the drainage cell price. Ultimately, it is not only about water. It concerns the future we are hoping to create– one layer at a time.
FAQs
Q1. How do drainage cells work?
They leave an air zone underneath soil or turf, resulting in the free flow of water along with minimising chances of becoming waterlogged or damaging the structure.
Q2. What are drainage cells used for?
They are utilised to have rooftop gardens, podium landscapes, planter boxes, driveways and vertical gardens.
Q3. Do drainage cells help with waterproofing?
Yes, indirectly. They do not allow water to be deposited on waterproofing layers, hence, increasing their performance and goodness.
Q4. Are drainage cells eco-friendly?
Yes. The vast majority of them are manufactured from recycled plastic and promote sustainable construction, such as rainwater harvesting and city vegetation.
