not a fan of haunching but on the budget jobs if done right its ok

I don't think it's a budget job!!
I have paid almost £40 a square metre for someone to dress blocks onto the base that I did myself last year.

after 2 days any concrete will still be green and easily broken if you bash it.

It's not concrete, it's a very weak mix of sharp sand and cement.
I have mixed probably 50 tons of concrete over the last few years on DIY projects as well as several tons of mortar. I know what mixture ratio are indicated by colour after a few day. Still having a reddish, sandy colour and crumbling under hand say it's been F*****ed up

Here are some pictures taken now. 2.5 days after mixing on Friday morning.
BTW I started this thread not knowing the quality of the haunching, as it was all covered by gravel. it was only on Sat evening that I noticed a few of the edge bricks had moved where I had stood on them that I investigated. So my original comment about generally pleased with quality (except the no concrete bedding query) was made not knowing about the shite job of haunching.

Sorry, don't think I was swearing at you, I was making a comment on the quality of work I have paid to be had done.
I appreciate your comment, and I know it takes 20 odd days for concrete to reach full strength.
Feel free not to comment, but these posts are useful to everyone, pro and amateurs alike.

Haunching is crap and will fail, cuts are not the best and don't adhere to British Standards but job looks ok aesthetically if you can push a shovel through the haunch after a day then it needs to come out and be haunched with concrete not screed.

concrete achieves something like 80 percent strength within the first few days then it becomes a very slow procoess to achieve the rest of the strength taking years,
thats rubbish stuff its more a decorative blinding than a concrete haunch

I have seen this method before but never tried it myself. So you screed the sand, lay the blocks then concrete the edge blocks, at what point do you compact as this is what I can't get my head round. Cheers guys

I don't think the op' is swearing at you lopad, more he is, as we all would be angry at the contractor and angry at himself for allowing the shite work. Yes i change my opinion and think the edging/haunching is a poor choice. The main body will start migrating once vehicles drive on close to it. Also the sand has to be wacked in and that will weaken the 'mortar.'

I'm just a DIYer but that's not concrete haunching at all down the edge, it will fail letting the blocks move outwards, you need to call this guy back to put it right.
Darts are not good at all they are very small and as said should be inboard cuts, I think the overal job looks good apart from the points already raised.
Good luck and please keep us posted of the outcome.
