Browse Forums Landscape & Garden Design 1 Apr 08, 2019 10:19 am Firstly i am new here so be kind as I find my way around! I am hoping to get some advice in regards to the best drainage practice on our very undeveloped property. In this first photo I want to put a drain in where the green line is along the driveway. Again, it is very undeveloped and yes all the weeds etc will be gone!! However I am bringing in several truck loads of 20mm minus for the driveway so I am wondering if I dig a trench and put some 20mm in it, then lay a 65mm or 100mm slotted drain and then cover it with the 20mm minus driveway material would that be adequate? Do I need the socked drain and will 65mm do or should I use 100mm? Will the 20mm minus be a suitable rock to use in the drain? The drain will ultimately terminate into a pit drain down on the flat house site. (There are several pit drains on the flat house site) Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ In this next photo I am going to put up a small retaining wall (small in height, not length). So again I am anticipating putting down a drain and 20mm metal behind the wall as per the drain above. Is this going to be suitable?
