[origin: EP0976874A2] A trench is excavated from the soil structure and at least one drainage mat (11) which is impermeable on one side is fitted to at least one of the trench walls and/or base before the trench is filled back in again. The trench is dug using an automatic machine (1) that excavates soil at its front end and fills the trench back in again at its rear end. An Independent claim is also included for the drainage mat.
