My house is on a sloping block and rain water during heavy downpours causes me a few headaches. Now when we had the real heavy rains on the 25th Jan (Gold Coast) the run off was intense. My thinking of a resolution is to do the following 1 - Level out the soil gradient on the lawn area 2 - Install bush rock garden edging (more for aesthetics but also to stop leaves and other debris items flowing down and blocking the drains) 3- Change pebble perimeter path with concrete that has linked drainage to storm water outlet and also a slight gradient against the house brickwork that will direct water to the drainage and away from the property. Before I embark on this exercise would any experts be able to run their eye across the images and advise if I am going to solve my issue. I already have drainage at points of the perimeter that seem ok and are linked to the storm water system but I'm looking at a long term option. I have a collection of images to help aid the info above Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Looking forward to your advice Re: STORM WATER ISSUE 2Mar 05, 2012 11:59 am One of the things to think about is with the sort of storms around Australia connecting to the public storm system won't solve all the problems. Most public systems are designed for once in 2 to once in 5 years. A lot of existing systems I have seen would be lucky to take a once a year storm. Once the storm is worse than the design storm the system backs up and can't take the water coming to it with flooding resulting. Things that help are permeable surfaces like gravel rather than concrete allowing the water to soak into the soil. Shaping the land to direct water to locations away from the house where it can flood without damaging the foundations or get into the house. The Harder You Try - the Luckier You Get !

Re: STORM WATER ISSUE 3Mar 26, 2012 4:57 am It seems from the photos that you have large garden area at back and the water from that area is getting to the house. You need to put in cut off interceptor drain along the width of the block to stop the water. Best thing is to put in spoon drain with direct connection to drainage Hope this helps you Foremost Building Expert in Australia,assisting with building problems/disputes, building stage inspections,pre-contract review advice for peace of mind 200 blogs http://www.buildingexpert.net.au/blog Hello I am developing 2 side by side units.
