Browse Forums DIY, Home Maintenance & Repair 1 Nov 04, 2008 11:37 pm This front retaining wall is approximately 1m in height from it's foundation to the top that you see.
It has commenced a lean in the direction towards the road, at the end closest to the limestone wall pictured. All 3 house services are running under the wall, this is denoted in the picture. The Wall is 1 brick (Width) thick, and there is only a slight concrete footing on the walkway side of the wall. I fear the wall will collapse at some point, possibly disrupting the services. I have an idea on how to fix it, though I would like some input and advice concerning its dismantling. http://tinypic.com/view.php?pic=zsvk9z&s=4 http://tinypic.com/view.php?pic=xo4ok3&s=4 http://tinypic.com/view.php?pic=6qyxk9&s=4 Re: Advice for repairing Retaining Wall 2Nov 13, 2008 2:32 pm Kevink,
Your post was looking very lonely here, so I said I'd post my 2 cents worth. I hate answering a question with a question but....... The first thing I would be asking myself is why is the wall commencing to lean now? What factors need to be addressed before I even start to repair the wall? Is the ground moving / subsiding? Is the wall foundation failing? Is the mortar joints in the wall failing? Are the services in the ground behing the wall leaking and causing soil movement? A few answers.... 1)I would be asking a structural engineer for his advice, he would examine the wall, and moniter the movement with gap indicators to see if it is still moving. 2)I would be consulting your local utility companies (Gas / Electricty / water)about the issue, if you do indeed need to rebuild the wall, and you accidentally disrupt any of their services, you'll be in big trouble. You may even find they will not let you do the work yourself, they may have their own preferred contractors to carry out the work. 3)I would be asking a structural engineer for his advice on, demolishing the old wall (without disrupting the existing services - temporary shoring of some kind?). He should also advise on a new retaining wall, with appropriate footing detail. 4)You may not have to demolish the wall at all, I know its common for structural engineers use ground anchors in similar circumstances to pin a wall in place. Again Mr structural engineer to the rescue. Hope this helps. Pat. Versaloc is a mortarless besser block system that still needs a properly engineered footing. If you just do a 400x200 footing it will fail in time. At 17m long you need it… 1 15501 Hi All, I engaged a tradie to install concrete retaining wall 600-800mm high over 32 meters in Victoria.
