The next project I will be tackling is the construction of a fence across the front of the house on the roadside. The requirements are that it be a height of around two meters (possibly a bit more at one end) and provide a visual barrier.
Currently I have a solid retaining wall in concrete at ground level for about 20 meters, it looks pretty solid and has no cracks in it. It has been there for I would estimate at least 30 years. And the remaining 10 meters of low block wall that has cracked at one end.
I am thinking of doing something like this, but I am uncertain about many aspects of it so I welcome any suggestions, even a complete redesign.
Remove existing concrete posts and old fence.
Repair low cracked wall by shuttering reinforced concrete on top of it, entire length of that 10 meter section.
Continue at the new height of the reinforced section in 20x20x50 lightweight block with a reinforced band of concrete or 'chainage' on top. This would be build upon the existing ground level retaining wall.
At this point I would have a concrete wall of 20cm thickness 30 meters in length by about 40cm at one end and a meter at the other (ish) Will have to measure that.
Continuing above to 2 - 2.4 meters in timber using class IV posts 150mm x 150mm and 215mm x 45mm x 2 meter horizontal planks.
I've attached some photos.
Do you think this is a good approach?
Will the existing walls handle the weight?
