When buying artificial grass for a balcony or terrace, it´s necessary to take into consideration the aspect of water drainage. First of all, we should avoid lawn that needs filling of sand or gravel , as this will be completely useless if is on a concrete surface.
To solve the drainage issue, before installing artificial turf, mesh drain must be placed, so it can remove rain water and prevent flooding. Furthermore, drainage plates have the advantage to convert the lawn in a smoother surface.
Maybe you want to save money when buying artificial turf for your terrace or balcony trying to install it yourself. This is possible because the area is not as big as a garden or patio. However, if you are not a skilled person in manual work , it is best to request professional installers.
