I'm now about to start a new patio and just wanted a few answers to some questions i have.
I am laying flags on an area about 7 metres by 5 metres, on about six inches of type 1.
Is it necessary to compress the type 1 with a compressor?
I am going to slope the patio away from the house to linear drains(I have very bad drainage in the garden). What is the recommended slope?
What is the best method for the bedding, morter or a dry sand cement mix, I've always used a dry mix before but i wondered it a mortor bed is more solid.
Cheers

Bascially, to answer your queries...
Yes, the sub base has to be compacted. If you are using 150mm of Type 1, then preferably it needs to be laid in 2 stages and compacted every 75mm, to eliminate future settlement due to improper compaction. I will add that 150mm seems a little overkill for a patio; 100mm should do the job on normal sub soils for domestic patios. For the record, you might want to use a 'compactor', not a 'compressor'...(ever tried pushing a chain?)
The slope away from the house, with the paving being 150mm below DPC, should be anywhere between 1:40 to 1:60 for most patios, dependant on individual site circumstances.
Good luck. Maybe getting a pro in to do it would be an easier way for you.

I had one twonk on the 'phone at 9:01am Tuesday morning. He'd emailed to ask what was the white stuff on his newly laid blocks, and I'd emailed back telling him to check the FAQs. So now he's on the phone wanting to know what are FAQs. I very briefly explained (hadn't quite finished my 3rd cuppa of the day and I'm useless until I'm into double figures) and then he asks if I can tell him what the FAQ will say because he's too busy to read it for himself.
It never ceases to amaze me how often a simple two word response seems to answer most of their queries, or at least it convinces them to put down the phone!
