Relaying Patio

[cambourne7]

Hi All,

Well were going to have to relay our patio as its not level and the pave-fix we used well we did not use it correctly so it did not set.

Were literally lifting the slabs up at the moment without any problem :(

The base was compacted soil and then a bed of sand. Yes i know your all screaming where is the cement but husband did not think he would need it :(

So this week were lifting the rest of the slabs and were raking off the top of the sand.

Am i right now in thinking that we relay the slaps with a mix of 1 spade of cement to 4 of sand relaying the slabs and correctly using the pavefix to set the joins between the slabs and this should stop them moving?

If thats correct how do i set the edging stones around the patio do i need to mix mortor or use the pave-fix?

You normally set all the edging first, in concrete, then work either inwards or from one end to another.

thanks i have let the husband know :)
I have invited a few friends around for a big roast beef dinner in exchange for some labour i am desperate to get patio back down so that i can get the grass in and can start planting things before they die or its 2 late to move them as it is i can see me semi planting pots :(

well D day is saturday i have roped in with the promise of a meal and beer after 3 men to help husband relay the patio which we have now fully lifted. Harriets looking out the window at the giant sand pit today :)

One end of the area (the bit with the most sinking) is about a 1ft deep with sand and we think that its just 2 much sand and even a sand cement mix will not do the job so were going to get a few bags of ready mixed cement and put that down just to give more stability then the sand cement mix on top.

Tomorrow afternoon when harriets having her nap i am going out with the weed killer and in the afternoon hubbie and i are going to start the process of lifting the sand up off the ground so come saturday they can just get started laying the cement at one end and starting laying at the other so my the time they have worked there way to the cement it should have cured a bit.

I used crushed limestone from a local builders merchants to fill the 12-18" needed for mine, then hired a vibrating plate (wacka) to compact it, with a sand/cement final layer. It hasn't moved at all in the 7? years it's been down.

yes, you need hardcore underneath to stabilise it really. Anything will do, find a skip[ where someone has torn a wall down, then set about the the pile with a sledge hammer and break it all up into matchbox sized bits. About 9 inches of that will be perfect.
