Thanks for the reply, but it was rather vague. I have read quite a bit of the website. Most of it really. Although very informative, I still failed to find the instructions/explanation why the trench for land drainage has to be 900cm deep for laying a perforated drainage pipe of 100mm diameter.
Would 600mm deep x 250mm wide trench work? 10cm bedding to lay the 100mm fully perforated and corrugated pipe + gravel or pea shingles all around the 100 pipe up to 100mm from ground level so I can fold over the geotextile membrane and finish with topsoil for the turf. All with a 1/100 gradient slope in the ground to allow water flow.
A simple answer/instructions would be most welcome.
