This is a marvellous idea a forum on Paving. Okay. My Brother in Law is a brick paver, however he is also an alcoholic so everything he tells me I try and double or treble check. He is telling me I don't need yellow sand under my pavers as I can lay directly on the black sand (WA). Previously I did that in Currambine, and it worked okay up there. However I have moved to Victoria Park and the sand here is completely different. The black sand here seems to have no 'guts' to it at all. My Wheelbarrow bogs in this stuff when it is just over half filled with sand. At Currambine I could load the Wheelbarrow up to overfill and still wheel it around no issue. So I suspect this black sand will not compact properly, in which case I will need yellow sand. Opinions or test methods please. In this paving project I have three boxes formed between the wall of the house and raisesd garden beds. Again at Currambine we had a similar arrangement however when it really rained (and it does sometimes in WA...okay about twice a year if we are lucky) and my soakwell couldn't get rid of the volume the paving used to flood. This time I thought it would be nice to have a gap around the edge of the paving which I could backfill with a decorative stone. This would create an interesting border and simultaneously act as a drainage point between the pavers and the raised garden beds (yes I am falling away from the house). I tried to set up the limestone retaining for the garden bed to enable a consistent gap around the paving without cutting (as much as practical anyway). This hasn't worked out as the block dimensions limited what I could and couldn't do. So currently according to my spreadsheet the design ends up with 50mm gap between the house and the paving and a different gap down the side and a different gap along the back of the paving area. I think this will look a little dicky and wondered what others thought. I also wondered what you may consider to be a solution which minimises cutting. I have attached my Spreadsheet however it is in MS Office 2002 format so to get it into an image I have had to convert through three different programs, hopefully it is readable. Has anyone phoned around Perth for hire prices of Compactors and who have you found most cost effective?

Didnt ring anywhere else as Kennards is most conveniant Re: Floating Paving and Sand 3Jan 31, 2008 10:23 am Your description of your brother inlaw cracked me up
He is right though. You can pave straight onto that sand. get a really good wetting agent (saturaid) onto it first and really soak it before screeding and compacting it. I know of many brick pavers who do this on established homes with great results for the years to come. I guess it isn't as easy to work with as yellow sand but it will cut down on excavating existing sand and the labour of carting more sand to replace the sand you got rid of. yellow sand is better and on new building sites, tends to be used because heights need building up more often than not. Hope it all works out P.S. most yellow sands become very hard once dried out. The other sands will take a fair while to become hard and compact but if you use a wetting agent (to get the water into dry sands) and a plate compactor you will be laughing. Re: Floating Paving and Sand 4Feb 03, 2009 8:09 am Just on the compaction side of things, I am having 60 m Sq of pathway laid this week (cost $4500). the formwork is already up and crusher dust is down. The problem is that this contractor doesnt believe that the crusher dust needs to be compacted. In some places your feet sink in about 1 inch. I asked "whats the go!" and he said that he always does it this way and that it will compact as the wheelbarrow goes over it.
Im not convinced that it will compact it properly, should I be worried? I'm putting a new floor in my kitchen, slate flagging on a standard concrete slab. I have allowed for a bed thickness of up to 20mm to accommodate the different… 0 17539 2 4351 2 8874 |
