hi,
I have recently asked a landscaping friend of mine to lay some paving slabs to provide a driveway, .
what we did was first dug out the area 8 inches deep, then filled it with 4 inches of hardcore, which was then compacted down with a whacker plate, to provide a solid sub base, he then dry mixed sharp sand with cement (approx. 1:10 ratio), and laid the slabs on this, is this ok, or does the mix have to be a wet mix?
what we did was lay 2 rows of slabs then a row of gravel, then another 2 rows of slabs athen another row of gravel then another 2 rows of slabs, and edging stone at the end.
this looked great until about 24 hours after it was finished somebody came to the house and parked on it, and one of the slabs moved,
I don't think he whickered the sand down, and the other slabs seem ok. and the pointing was also done using the dry mix.
but because its being used as a driveway, my main worry is will it last if the slabs have be laid on a dry mix of sand and cement?
thanks for reading,
