Block paving over concrete

[David 1234]

messages crossed - I got two and a half large. Ridiculous really - they should spend their money researching how to get rid of a problem instead of denying everything and then paying people off. The funniest thing is that they still claim that my problem was a one off - don't they realise that people talk. After I put my photoes up the forum went mad - I wonder how many other people there are out there who have accepted the initial fob off.

she got 4k back, the cost of the flags were 2k and 2k compensation but the patio is still there as it would be a crying shame to remove it after i had spent 10 days constructing it

they was arguing the toss over my price to remove the patio and relay it, what they did not understand is I had no where to works as there is metal railing between the garden and the rear of the house to keep the dogs off the grass plus the lawn was brand new after i had constructed the patio so it meant having to replace the lawn again once the work had been completed

and the customer would not accept any other contractor to replace the granite

because i had laid it without any joints what so ever they could not remove the 6 - 8 really badly marked flags, there was more marks flags but these looked the worse

so after they had sent some young lad to seal the granite after i had laid it even though it was brought to their attention before i had started to cut and lay the patio, he turned up unannounced and made it worse by sealing it on a damp morning

months and months had gone by and nothing was happening until finally it was sorted, like you say though how many people have been fobbed off and got nothing





anyway good luck with your block paving and I am sure it will go smoothly this time

thank you - and that patio is fabulous.

remember that post but mick I've noticed that one of your soldier course blocks are out by 1mm, tut tut. lol.

mick, you take a pride in you work and it shows (as do all the pros on this here). Sean reminds me of my foreman when i was a boy, neatly and correctly is the only way to do it. :p

au contraire, i agree with drilling holes. I just don't agree with sand ( flexible ) on concrete ( rigid ). Sorry mick my intensions were'nt to have a go. my foots firmly in my gob.

I don't mean an disrespect here I have enormous respect for you all but I think a fin drain would be a cheaper and quicker solution for the client. My reasons are that a driveway of 90m2 will require 400+ holes which is 2 days labour and the purchase of a couple of core bits and the hire of the drill. Also the purchase of the geotextile. Thats £650 +vat min whereas a fin drian would cost half that and be installed in 2 hours. I used some recently and it cost about £2.80m2 from Burdens the membrane added a further 60p m2. The drilling is a great idea if it's a diy job but it's perhaps not the most cost effective if you're paying someone to do it. Please don't take this the wrong way I'm only offering it up for discussion.

so instead of the sand, why are'nt you using permeable grit? sand is always going to get ' fluid'.

[David 1234]

permeable grit Sean?

[seanandruby]

i apologise, sorry bad grammar. Just grit then, to make it permeable. 2 to 4 ml, as you would use on permeable paving. I reckon if you are drilling holes in an existing base, then fill with stone etc; you need to be sure the water is going to get away. What if the subsoil is clay and the water builds up? The sand will become fluid, thus compromising the finished paving, eventually. Grit will stay firm. Proper drainage is needed. ???

[mickg]

that does work but it takes a lot more kiln dried sand to fill the joints in the block paving due to the kiln dried sand having to fill the 6mm laying course gaps too

[Mikey_C]

what about the recycled glass paving sand that can't hold water?

[David 1234]

Thanks. I was also thinking the same - as it's clay soil then small drainage holes may never work....the same principle as putting a soakaway in impervious soil.

I'm beginning to think a rigid driveway is the way forward - any reason why Romex couldn't be used in place of mortar or kiln dried sand? The only issue could be that I think all Romex products require at least 8mm joints.
