First of all I got to say that this site is fantastic, however with so much information I am getting confused the more I read various pages not to mention other sites and the advice from various contractors all of whom say different things. So some help on here would be most appreciated.
Picture of work so far
We currently we already have a 4-6 inch solid concrete base and on top of this the contractor is meant to lay Marshalls Argent paving which are 38mm in depth. The DPC will not be compromised in any case so no problems there.
My question is this… How should the contractor be proceeding from here?
Currently he has mixed some dry sand with cement and laid it over the concrete base. I suspect he will lay another layer of dry sand with cement mix and then place the paving on top of this. He calls this dry screed.
What is the ideal depth of the dry sand/cement? Does it matter if it is 3inches or 4inch in place for level matching? Because thats what I think it will be in order for the levels to match up with the outside pavement.
What is the right way to do it? And will this be strong enough to take the weight of a car?
Should he be using wet mix / screed
Do I have to worry about drainage of the bedding layer if he used dry sand with cement?
Any help on this would be most appreciated.
Thanks in advance
Stephen
