Pointing on a new patio....

lol, block paving dont move up and down. if it goes down it stays down,it ceertainly dont come back up in any way. you clearly dont understand the qualities of compressed sand.

There are few constructed surfaces that do not 'spring' or 'trampoline'.

Engineering bods take this into account when designing and building roads and paved surfaces.

They go down and they come back up again.

FACT.

You seem like a bright fellow ashymo', why so argumentative?

cos i know im right.

cos i know im right.

Next time you see a very heavy lorry back onto a drive or side road, watch the road surface.

Carefully.

indeed

a road i put in in Ramsey Cambs had a huge amount of construction.

but the ground beneath the road is all fen peat so it is always on the move.

however i dont think you want to be backing to many heavy lorries on to domestic drives as that would be asking to much of 150-200 mm hardcore.



i think ashymoko is talking about subsidence or sinkage due to bad construction so id assume he would know a lot about this particular problem lol.

i dont think i need to say anymore on this subject!

Must be hard work having two accounts......

None of you have a clue what your talkin about.

The paving will only become flexible if the subbase or ground below moves or gives. Which unless your on clay or bad ground wont happen.

When the sands compacted it reaches its maximum density and thats that.

Not been on here in quite a while but have certainly enjoyed reading this.
I dont really like to critisise peoples ways of working but I think laying stone on a screeded bed is asking for trouble, my paving always goes down on at least 4" of 50mm dolo compacted with a plate and then laid on a full bed of wet building sand and cement. That way when I leave that night I know im not going to have any loose the next day before grout goes in.
The only time I ever lay on a screeded bed is if im on sitework laying something at least 60mm thick.

Our pointing is always done with a semi dry grout with enough water in it to see the water come through when its compacted and striked this way I know I dont mark my stone and I know I wont get any problems.
If im using something like polished stone or a nice indian stone I tend to use geofix.
