Pavers (strip 1 paver wide) - sub-base, how to lay etc.

mardi 1 avril 2014

Hi,



I'm looking for some advice about putting pavers down. We are building a small decking for our shed to sit on, but it needs to be built slightly away from the fence line to allow for the overhang from the gable roof. We decided we would put down pavers around the base, so it doesn't just become a mud path. It won't get very much foot traffic (except for a few just where the door to the shed is.



The pavers are 400x 200. They will only be 1 paver wide for e length, which means that we don't really have anything to keep them from shifting from side to side. We have dug out the garden bed that was on part of the area, so it is pretty level. We are going to get a compactor to run over the whole area.



Just not sure what to put down as a sub base under the pavers. As they will be button between the fence and the shed on 2 side, I won't be able to get back in and fix it if they do shift, I was thinking of putting down crusher dust, and possibly mixing it with concrete.



Just wondering if people think that this is the best sub base to use? Should I mix it with concrete? What type of concrete do I use? What ratio do I mix it with? Do I need to wet it? Do I need to compact this once, if I have already compacted the dirt underneath? Should I build a border with wood to make the channel to lay the pavers in? Once I've done the sub-base do I put down a layer of washed sand & screen it? I googled quite a lot about laying pavers, but as there is only 1 paver wide it was hard to work out what to do in my situation. It said that you normally use a bit of mortar for the pavers on the edges. Should I use mortar at the edges? Do I use mortar between in the gap between the pavers? What space do I out between the pavers to stop any shifting? Do I put gap sand down once I have laid they pavers? Do you roll the compactor over the top of the pavers once you have laid them and put whatever substance between the gaps, or just bang them with a rubber mallet?



Anything else I should consider before proceeding?



I was thinking of getting somebody in to do it, but people were asking over $400 to do the job, even though they ground in prepared and there is a total of 26 pavers to be put down, that we have already bought. I figured that I could probably manage it myself, especially as it is only for edging and doesn't need to be perfect like a driveway.



Thanks so much in advance.



Yael
