Some decking projects require to rise the basement for at least 30cm high. The traditional method would be to make a metal frame as a support, then install the decking onto the metal structure. This method would increase the time and human cost, so for the developed countries, this method is not so pratical due to the high human cost. Right now you can use our pedestals for this application. You can see the pic below to have a general ideas. The height of the basement can be adjusted. Contact us for more information.
