Browse Forums Landscape & Garden Design 1 Feb 04, 2016 8:58 am I’m finally coming to the end of a very long landscape journey (we moved in nearly 9 months ago). I’ve still got a retaining wall to build on my rear boundary (just waiting for the DA to be approved). The side fence should be going up in a couple of weeks and then it’s on to turf! I was doing some measurements yesterday and it turns out the backyard isn’t as level as it seems. There’s 11.5m between the house and the rear boundary and the ground is 250mm higher at the boundary than at the house. The level at the house is where it needs to be so I can add soil and turf and finish at the right height to the slab. I was also planning on adding an agg line for drainage against the house. My question is, how noticeable would the slope be after it’s turfed (the area is 11.5m x 20m) and should I level it for drainage anyway (or will the turf + agg line be enough)? Re: Backyard not quite level 3Feb 09, 2016 1:15 pm I would watch when raining if water pools against slab as over time water will go down to slab even when concreted if there's a gap between house and concrete and theres not enough slope away from house, builders love blaming you if there's slab trouble, so drainage away from house number 1 Landscaping a distant second. Re: Backyard not quite level 4Feb 17, 2016 8:29 pm Can you please post a picture of what it looks like now. I think it would be ok what I would do is build the level up against your slab by adding soil and have a slight noticeable decline away from your slab for about the first metre this will allow water to run away from your slab and seep into the ground. As for the back boundary being higher I wouldn't be to concerned as your backyard is quite large compared to some. Ag line would be an ok idea as well but how much are you prepared to spend I would only add agline if water is ponding or pooling near your house slab otherwise I would only do it if you have money to burn.

Soak wells need sandy soils. 10 6181 Need advice on the backyard plan above. Should I excavate and cut all of the dirt to level with the house slab or semi-excavate as per photo above?
