Removing old patio and replacing

[Wightas83]

Hi all. New here.

I inherited a patio about 8m x 4m. Quite old and had became quite uneven. I have taken up the old 600 x 600 flag stones and plan to replace with something a bit more decorative. I was hoping that given that a patio was already down then the work to prepare the base could be kept to a minimum. What Are people thoughts about the best way to move forward from here

Appreciate any advice or opinions.

Cheers

The old patio will have been uneven due to the sub base not being good enough and/or movement due to the tree roots
In my opinion, having a tree that size so close to paving is going to cause problems. That's not to say you can't lift a few slabs in years to come and relay them.

ps the old slabs are worth a couple of quid each

As above.
Remove the old sand and weeds.
Remove any roots.
Regulate the base if its over depth so you need 30-50 mm of bed for new paving.
Lay some typar pro sheet or heavy duty landscaping weed control.

Lay new paving

Cheers for the reply both, appreciated.

Just for me to clarify. Once I remove all the old sand and weeds and get the height correct I would then lay 30 to 50mm of sharp sand. Then were control. And then lay New paving?

Cheers

Weed control sheet under the sand .
Ideally sand and cement mix for slabs.

The weed control is not essential but will help prevent small roots and worms from mining the sand.

If you use a good bed of 6:1 sand cement that will go quite hard anyway.
