Maybe they did not actually think about it. The idea of having the garden bed in my opinion will purely be for aesthetics. At the end of the day, if you have proper drainage and the concrete slope away from your house you will be fine. May be if you want peace of mind, you can raise the level of the concrete a bit more than you actually need it to be.

Maybe they did not actually think about it. I think they will tell me to sod off. The house next door is a so called builders ready built house, still vacant, the for sale sign has been there since the very beginning. I know who the builder is though.

If I have the choice, I would rather have a full width of concrete path so that my little boss can practices his tricycle drift there, unfortunately, as you can see from diagram 1, I cannot build up that area due to the builder's stupid slab foundation and 1 brick course dam-proof construction. My concrete path must be at or below the house slab rebate according to Guide to Standards + Tolerances. I'll need to plant some screening trees in pots there anyway, so a raised garden bed kinda make sense, it also saves me some precious life time waiting for the screening tree to grow higher. Diagram 1 Diagram 2 Would this be a better option?

It might be a little bit costly but it will look nice and you will have peace of mind. Re: Landscaping, Concreting and drainage issues 9Nov 18, 2011 11:52 am Going from the site plan you already have a storm water pipe in the middle of that section of land anyway. IMO it would be easier to put the drain inline(in the middle) and have the fall toward the garage as that is where it appears to be going anyway. EmeryBB I cannot build up that area due to the builder's stupid slab foundation and 1 brick course dam-proof construction. I cannot see why this would cause an issue. Reserving space for a long winded/detailed answer but I thin Diagram 3 is suitable. If you want a garden bed I can draw up something that may work. It is all going to depend on the depth of the current storm water pipes, regardless of which option you take. I would dig them out tat the garage and alfresco to measure how much depth they have and how much fall there is before doing anything.

Hi thegourou, is this what you mean? so you reckon that channel should be able to handle the waters from both sides?

IMO it would be easier to put the drain inline(in the middle) and have the fall toward the garage as that is where it appears to be going anyway. That's what the other 2 concreters said, a grate style drain near alfresco and a channel grate right in front of the roller door. chrisandkate EmeryBB I cannot build up that area due to the builder's stupid slab foundation and 1 brick course dam-proof construction. I cannot see why this would cause an issue. It's not an issue as long as I don't concrete it higher than the bottom of the first brick. It is in the Part 3.3.4.5(c) of the BCA, Damp-proof course-installation states that "the height of a damp-proof course, or flashing serving as a damp-proof course, must be not less than 150mm above the adjacent ground level; or 75mm above the finished surface level of adjacent paved, concreted or landscaped areas that slope away from the wall" Quote: If you want a garden bed I can draw up something that may work. Wouldn't mind some new ideas, it's mainly for planting some screening trees there.
