Geotextile filter fabric is usually a type of non-woven. This geotextile product has very important benefits in drainage systems. Often, drainage cell geotextiles are needed to help drain water. Therefore, in a drainage system, the presence of this material helps to drain water more quickly.
The Importance of Geotextile Filter Fabric
The application of non-woven geotextiles in the modern construction world is indeed beyond doubt. This technology is evolving and offers various benefits in water usage efficiency as well as improved drainage.
With advancements in materials and application methods, non-woven geotextiles have now become the primary choice for enhancing the performance of drainage systems on green roofs. In green roofs and podium landscaping, this geotextile acts as a filter layer and also a separator.
Geotextile filters are very effective because they can separate materials and water effectively. This way, water can directly enter the drainage and flow without any issues because other solid materials are retained.
How Geotextile Filters Work in Green Roof
This geotextile fabric has its own way of improving drainage performance. First, the fabric acts as a filter that retains fine soil from the planting medium (substrate) so that it does not wash into the drainage system.
This role is very important to prevent the drainage cell from becoming water-saturated or clogged. Furthermore, the geotextile filter will optimize water flow.
Non-woven geotextile will ensure that excess water on the green roof or podium flows smoothly to the existing drainage system. This water flow is important to prevent pooling because it can burden the roof structure.
Beside drainage, geotextile filters are also often used as a protective layer above the waterproof membrane in green roofs. Their presence prevents punctures from plant roots or sharp materials that could damage it.
By preventing fine soil erosion, this geotextile filter also helps maintain the stability of the podium soil structure or green roof. This material helps prevent soil surface subsidence and ensures that plants grow healthily because soil moisture is preserved.
Combination of Drainage Cell and Geotextile Filter
To keep the drainage system effective, a combination of drainage cells and geotextile filters is widely used. Geotextile drainage cells are generally in the form of hollow plastic panel blocks (PP/HDPE).
The material is designed to reduce hydrostatic pressure and support soil loads. The combination of drainage cells with non-woven geotextile on top as a filter makes the system very efficient for green roof drainage, planter boxes, and even basement areas.
Geotextile will prevent soil from entering and clogging the drainage cell cavities. This combination is known to be environmentally friendly because the material is recyclable and durable.
So, this filter geotextile will function as a separator between the planting medium, such as soil, and the drainage layer beneath it. This way, the planting medium or other particles will not cover the drainage voids.
That is actually the function of geotextile filter fabric and drainage cell geotextile in a green roof. The presence of both is very important to maintain stability so that drainage can function properly.
