I'm putting up a retaining wall. This is the second one I'm doing. The first one I did using 25kg bags of concrete and it cost me about $300. Man, it was hard work but I managed to do it. For my second retaining wall I'm thinking about prepping the site and then getting in a concrete pourer to fill the holes. I am looking at 9 holes about 700mm deep and 200m wide.
Would I be better off hauling 25kg bags or getting a concrete pourer in? Thanks

ask at your local readymix place or similar, often they will have a bit left over after larger pours which might be enough for your job and they are only too pleased to get rid of it at a cheaper rate

Pardon my ignorance here, what is a "readymix" place?

What are you putting in the holes? 700mm deep suggests wall about 600mm high but 200mm diameter means skinny posts or no room for concrete.

Ready mix = your local concrete mixer plant

When getting a metre price for readymix check that there isn't a minimum charge.

There will always be a minimum charge. You can't expect them to deliver $40 worth of concrete.

Could always hire a mixer,have the aggregate delivered and buy the cement .

If you are fit the cheapest way is to buy builders mix and cement in bags and mix in a wheel barrow. I did this for one of my retaining walls. The dearer way which is easier is to buy extra strength quick crete bags and tip them in the holes with water.

I saw a tarpaulin being used to mix concrete on recently - the sides were able to be lifted to move the mix as it was blended.

Only a small amount required there. Depends how much you enjoy hard work. I recently mixed and poured 16 holes with 100 x 100 posts in, each 900 deep and some quite wide. I used 1cu metre of builders mix and it took me about 2 hours.
