Hi all,
Does anyone know how much it costs to build the rock (or boulder) walls, that I've seen around the Vinuela area? And who constructs them. Think I prefer them to the solid concrete ones.
Many thanks.

A retaining wall is a completely different kettle of fish as it has to be designed to cater for the huge pressure behind it and has to have substantial foundations to distribute the load and cater for the overturning force. It also must be adequately drained.
Make sure your wall is professionally designed, esp as it's 6m high - I've seen too many retaining wall failures here already! Here's just one:

Your advice and comments much appreciated, guys. Thanks for giving me a starting point.
I'm sure our builder gave us a price of 200 euros per cubic metre, for a steel reinforced retaining concrete wall. I'm only going off my (very poor) memory, and nothing was written down.
If that's the case, then I'll certainly look into it.
Thanks again.

hilly thats a brick wall - look at the crack lines at the bottom.
a retaining wall is normally made of concrete - with a metre deep and wide base followed by a 250mm thick concrete reed bar steel reinforced wall on top.
i can get a price for you per m, if you are not too far away from alhaurin / coin. (i know the guy has worked in fuengerola and marbella before - he´d have to see it to quote it)...
you can always put a "rock" wall in front of it to "hide" it ? but erm.. rocks wont hold anything - they would have to be BIG rocks.

SpanLad, a retaining wall can be constructed of anything - bricks, blocks, concrete, even timber or earth or old tyres! The depth and width of the foundations and the width of the wall depend on the nature of the material behind and the height/weight being retained. Every individual retaining wall should be designed for its specific situation - it's not something you can "buy off the shelf". Unfortunately builders think they can and that's why so many failures occur.
The crack in the photo above was cause by outward failure/rotation of the retaining wall at the end of the terrace. It also caused the terrace to subside and fractured the drains so was very pleasant!

So right....A retaining wall is a completely different kettle of fish as it has to be designed to cater for the huge pressure behind it and has to have substantial foundations to distribute the load and cater for the overturning force. It also must be adequately drained.

A qualified builder would not think so...but others who build might think they can...and that is why so many faliures occur.Unfortunately builders think they can and that's why so many failures occur.
