Help...before my hillside collapses! I live in a coastal suburb of Sydney and I have a long steep sloping driveway that traverses a hillside. In the last 12 months the rock wall has developed some large horizontal cracks and a bulge at mid height, about half way along the driveway. I am worried it might all collapse and the dirt from under the agave will all fall down onto the driveway. The photo does not show the steepness and only shows the bottom of the driveway. Help!!




I think you would need to contact some local builders who will come round and look at the wall and advise you on what step to take next. Also what a lovely drive way! Love the purple flowers!

Thanks Catty, I have since swept up the fallen blossoms! I am on a budget but think I might actually need an engineer. There was a landslide further up the hill resulting in a neighbour losing his front lawn. The task of removing and replanting some large hibiscus shrubs further up the drive is what I am really feeling worried about. It would be a rather daunting task to save and replant all the shrubs. We alternate between droughts and bushfire danger, to torrential rain here!

Wow, that's alternating weather! I know it could be expensive but i do think it is the best way to go to avoid future issues. If it did ever come to replanting the shrubs just keep in mind that it is for the best and maybe get some help from family and friends?

A landscape architectural company should be able to advise you.

Thanks for your helpful answers. A problem shared is a problem halved, so they say. Goodnight. It's late down

It sounds like the wall is under stress from the weight behind it. This will increase if water can't drain away so one solution may just be to make some drainage holes through by drilling or removing the mortar around some stones.
Do you have insurance? It may be worth speaking to your insurers first as they may have approved contractors who can advise you.

How do I say thanks?
