Repairing garden patio advice

Hi
I have recently move in to a new flat and want to refresh the garden patio. It has buff coloured tiles which have quite a bit of mould blackspot on. I am going to pressure wash to clean them but then also need to grout them (all of the previous grouting has decayed). The gaps are of varying sizes (approx 5mm to 30mm), can anyone advise the best mix for this? I was planning on using a dry mix with three parts sand and 1 part concrete.
Also the slabs were laid on soil rather than a concrete base. Some slabs are stable however a small number move when i stand on them. Can anyone recommend how I can fix these slabs to the ground e.g. lay them on self levelling compound?. I asked a couple of people to quote for repairing this but got quoted £2k which is outside of my budget.
Thanks
Oli

    Well... If the slabs are just plonked down on soil, you'll be wasting your time grouting the joints. Ideally, they need lifting, a proper base prepared, and then relaid on a bed of mortar. Then, and only then, can you grout the joints and expect them to last - Also, you will only need a six part sand to one part cement (or even 8:1). A 3:1 mix will be very hard & brittle and break up in no time.
    Any language construct that forces such insanity in this case should be abandoned without regrets. –
