Lightweight Materials For Roof Garden
| February 15, 2010 | Posted by admin under Home Improvement |
Lightweight materials for the roof garden is now beginning to grow as the development and awareness of forestry on the environment. Especially in large cities, the role of roof gardens help efforts to promote the Go Green campaign. On this occasion I discussed about one of the supporting material to build a roof garden.
Roof Garden Structures Technology
One of the materials used in the structure of the planting medium is a conventional tech roof garden stone. Material posted one packages with these fibers, are laid on concrete plate, after the waterproofing membrane. Its function is to form cavities in the layer of planting medium, so water from the surface of the media can flow downwards. While the fibers are placed on a layer of river stone, serves as a filter, the water flowing down but keep the planting medium grain so as not to clog the sinkhole.
However, the use of stone 20 cm thick concrete slab makes the load becomes heavier. Therefore, in a modern roof garden or roof garden is often referred to extensively, stone material and the fibers are not used anymore. His replacement is the drainage cell material. Material from these plastic materials are usually sold one package with a layer of “mosquito net”, called geotextile, serves as a filter to replace the fibers.
Drainage Cell More Lightweight and Strong
Drainage cell is one of the products made from materials geokomposit. Geokomposit itself is made of plastic material types of HDPE (high density polyethylene), which has the properties of elastic but strong. Aside from being a drainage cell, HDPE plastic widely used in other landscape elements, such as paving grass, grass block of concrete replacement. Drainage cell Elmich which it is mediated by the PT. Trisigma Indonusa for example, able to withstand loads up to 100 ton/m2.
The elastic properties of HDPE drainage also makes cell can be made in various forms, such as sheets or panels. Drainage is generally flat-shaped cell has a thickness of 1 cm with a weight of less than 1 kg/m2. While the panel form (50 cm x 50 cm) had a 3 cm thick, weighing 2.5 to 3 kg/m2. Compare if you use stone 15-20 cm thick, will increase the load on the concrete slab 100-150 kg per m2.
In general, drainage cell 1 cm thick is used in shallow rooted plants such as groundcover plants. While the thickness of 3 cm is used for deep-rooted plants, such as woody plants.
Drainage Cell More Easily Installed
Another advantage of the drainage cell is easy to install. Drainage cell in the flat, simply “held” over the concrete slab, such as doing carpet. At the drain, cut cell-sized drainage hole and the hole diameter wire to hold the sheet geotextile given.
On-shaped drainage cell panels (50 cm x 50 cm), we simply arrange the panels so that the closed surface of the floor. Linking drainage cell panels with other panels, simply done by linking and locking hook which is already available on each panel.
Drainage Cell can also be Saving Water
Drainage cell is not simply miss the water from the upper surface of the planting medium to the bottom, but there also can save water. Water flowing from the top, largely accommodated in the bottom of the bowl-shaped cell. Drainage cell is usually used on the roof garden, where plants need moisture to the roots system.
Despite having many advantages, the use of cell drainage as a subsystem of a roof garden in Indonesia is still relatively rare, is caused by these materials are imported. While the geotextile filter is imported, there is also a local product.
