Hi. Not sure if the image above has come out but i'll give it a try. if the image is there, you will see the problem i have. The wall of the house has got a rendered section at the bottom and the adjoining wall hasn't so when I come to lay my edge restraints, the ones which will butt up to the wall will be out of line with the ones against the house. What is the usual method to get around this problem. Thanks. John
Ok thanks I thought that would be an option. Ideally I would like to lay them lengthways so I can get a channel drain closer to the house. Would it be ok to keep them all in line and put a few mm of concrete behind the ones up against the non rendered wall. Thanks.
You *can* offset the blocks from the wall and fill the resulting joint with coarse/sharp sand or mortar. It may well be more prone to weeds but it's a simpler fix than the cutting option, which gives a better looking, if technically more difficult, finish.
