The bedding product encompassing a land drain has considerably larger sized pores among Just about every stone, supplying extra space with the groundwater to occupy.
50 percent-perforated pipes are laid 'holes up' or 'holes down' dependant upon their supposed use - see diagram. In the majority of programs, the pipes are laid Using the holes to The underside on the pipe; the hydrostatic gradient mentioned higher than makes certain that the pipe functions to be a conduit for groundwater.
