Pool pavers sinking

Last year we noticed some slabs around the pool, at one end/ corner were wobbly.
Now after a winter of rain followed by very dry weather it is a problem that needs sorting.
For 4 months my husband has said dont worry it will be done before visitors arrive.
Now its I’ll just block that end off.

I’m really worried the pool will move, he assures me it wont.
I’ve spent hours looking on line for someone who could come out and fix it but I dont want anyone who will perhaps damage the pool.
I know of a builder in our village whio is reliable but has a very long wait. And i dont know if he deals with pool paving.

Any advice gratefully received.

Pavers or pool copings?

Its paveds, 2 years agk some loose pool copings were fixed that end, the pavers looked fine at the time.
That corner keads down steps and there is a little pool house at the bottom of a ? 4ft slope.
The pool house look structurally fine i think.

Have you asked him? If he can’t do it, maybe he’ll recommend someone else, who can.

Apologies for stating the blindingly obvious (but worth remembering). When you first noticed it that was the moment to book him.
(Sorry feeling smug) Our pool moves all the time because it’s on clay on sandstone. The pool surround was replaced about 5-6 years ago and there is a line of grouting that always cracks and opens. Had the guy who did the work back to look at it last autumn. He said he would do it before our guests arrived this summer. Even with that promise I was lucky to meet him in Leclerc’s carpark last week. He came round this Monday and our guests arrived Wednesday. Good builders are always busy but can be made to feel guilty if they have promised to do the work seven months ago!
PS: (edit) and stop believing you are going to do that type of work yourselves (taken me years to accept that one!)

No. I should have done but my husband kept insisting he would sort it.

It looks like settlement from back filling. I had the same as we used the spoil from the dig compacted hard but over 15y it sank and needed a bit of more mortar to re level. You should not us spoil but it should be self compacting stone like pea gravel then a reinforced concrete slab, learnt that after I joined the industry.

So you put pea gravel in to the ground thats moved and at what level do you put the concrete?

Pea gravel should be used around the pool walls to back fill. Concrete should be on top to form the terrace and finally pavers on the top.

What’s pea gravel Corona? I might need a spot of it myself as a hole has appeared beside the skimmer :face_with_hand_over_mouth: Nothing a bit of shovelling won’t fix I’m sure, but should it be from the the pile of tout venant I just happen to have lying around or pea gravel.

Tell your husband to get his finger out and fix the bloody problem. I’m old school as you might have guessed :face_with_hand_over_mouth: The last thing I would do is dump this house maintenance stuff on my wife.

Keep the pool and dump the husband I say :joy:

Just gravel the size of peas rather than the larger stones

Some good advice here. Includes diagrams.

That’s really helpful, thanks.

The bit I’m not sure of is where to start as the pool is already in place.
And if to just top up what’s there or dig out and fill with pea gravel.

I don’t want the pool to move, although my husband says it wont.
Also do we start with the pavers nearest the pool or furtherest away?

So many questions.

Thats what I woud do.

The pool won’t move as a consequence of the terrace slabs not being properly laid. Movement will depend on how the pool structure was designed and built in the first place.

The closer you can get your terrace back to how it should have been done (See diagram on the link sent) the longer it will remain sound. Proper foundations are the key.

If you want a very quick short term fix, lift all the loose slabs and dig out any large stones/large gravel/soil; level out with pea gravel then re-lay the slabs direct on top of that with some cement dabs. That will last you a few weeks if treated with care. But it is a very short term temporary fix.

To solve your issue properly is a big job.

It kind of depends what is currently under the pavers.
