A geezer laid a new patio for us last summer (legitimate garden company). It sorted of looked OK but finshing was iffy and now it is falling apart.


He laid it on dried sand and grouted in-between. The grout was soft, water is getting in, the slabs are lifting and eventually fauna and flora will get in.


I of course have have office worker's hands so will know nothing (despite repairing houses, cars, motorbikes and bike for 40 years) so our follow-up convesations will be interesting.


I'd rather just say give me half the money back and I'll get somebody in decent.


Questions: I know that you can lay on dry sterilised sand and grout, but I'd prefer to use a wet mortar mix (say 4:1)- views out there?

What do I do will all the old sand (can soft sand go into the garden, sharp sand is good in clay areas)

Recommendations for a small patio job?


Should have gone with my instinct and not used this local company. I'm not in a postion to name and shame quite yet.

On Barry Rd ,about 171 ,there's a forecourt that has just been laid with blocks .They are still working on it .

I was admiring the workmanship and the guy was explaining how it's all in the preperation ,which he was describing .


I'm sure he'd be happy to describe the ins and outs if you wanted to pass by on Monday .

I'm about to lay a patio, having broken concrete etc. in preparation the past few week-ends.

Question: when I dig up where I'm going to put and compact the hardcore, do I need to put a wooden "frame" to hold the hardcore or would the "walls" of the hole provide sufficient containment. Does that question even make sense. I have soft programmer fingers.

A sawn finish wood frame, pegged at the ends and fixed, is good to contain the hardcore and concrete/lean mix stage. IF you're going for slabs as a finished patio, you remove the frame pre-laying.

You'll be fine, once you start digging down you'll find that London clay soil is fairly rigid.

Will the patio form an edge to a lawn or garden border? If so you might want to reinforce the edge, such as an edging fully bedded in concrete to provide an edge that isn't go to move...

    • Or who's done what to who
    • Hi, hoping for a bit of help from the forum hive mind so thanks in advance.... Our property on Barry Rd was included in the External Major works that took place in 2022 (Dulwich Externals QHIP 19/20 Street Properties).  Recently we have discovered that Saltash, the contractors who carried out the work, basically patched and painted instead of fixed or replaced rotten window frames and didn't do anything to the cracked brick work which has now caused a bad case of damp in our property. Does anyone whose property was included in the works have information of any warranty or guarantee of work that was promised by Saltash or the council? As we moved in just before the work took place we weren't privy to the original communications around the work and I'd like to know where we stand before approaching the council to get it fixed..  Thanks!
    • used to love Meson don felipe with the funny guitarist who used to climb up and play on a podium, still a nice lively atmosphere and we still pop in if at the young vic but there's a lot better Spanish eateries near Borough market which is closer to the Tate too. Barrafina, Brindisa (though neither are cheap) and a few weeks ago we tried one called Parrillan, where they bring a little grill to your table and you cook your own tapas - this one certainly ticks the box for quirky but the portions are small so the bill can mount up.
