Loose paving stones

pmlindyloo

Many of our paving stones (think patio slabs) have come loose.

We have attempted to prise them up in order to relay them by leveling underneath with sharp sand.

To our horror we have discovered that they have been laid incorrectly. They appear to have been cemented at the corners.

When we attempted to remove one the corner of the slab broke off :eek:

Apart from taking the whole lot up and redoing, which we can't afford, is there any other solution?

A gardener friend suggested that there is a new (?) product which you can 'sweep' over the slabs and it will fill the spaces underneath and 'level' them.

Can anyone help?

Have tried to find this product with the help of my friend 'Google' but no luck.

I started my working career 30 years ago as a pavior - once the integrity of the foundation has gone its time for a relay i am afraid.

using mortar is common four corners and one in the middle is the norm - when i was an apprentice one of the jobs you got when relaying was to knock off the mortar spots with a bolster chisel, this is fine when the paving is thick enough to withstand the hammering - in your case it appears the slabs are a little thin and so just break.

one method to save money you could use is to prize up the paving stone at the side that is low, just enough to get some sand into and under the joint and gently tap back into position ( you might need to lift and sand the adjacent corner or the paving stone may rock)

once complete there is a dry product out there you can brush into the joints to seal, although i would always go for old fashioned pointing.

I must stress the only true way to sort uneven paving is a complete relay but if money is to be saved money is to be saved

hope this helps a little

Thank you so much for this.

Have you any idea of the name of the dry product you can brush into the joints?

I am not sure, but i used it on my brothers house last year, we laid decorative paving and did not want to stain it - it works well but is relatively expensive, off memory i think we used Travis Perkins but i am sure any main builders merchants will stock it
