Lime base - Paving contractors have laid a lime base

[Danielwood]

I posted previously about the lack of bedding sand on my block paving. I have now spoken to the people who have said that they what they have laid is a lime sand mix which will harden to a crust over the next two weeks and will act like cement they also claimed it is mostly done in the south.
I have looked searched online and not found any mention of this method. Is it a valid method or are they still looking for a method to get me to pay.

Cheers

Does anyone now of any block paving inspectors in the north west that I could hire to do an inspection ThanksPrevious Post

sounds like bullshit to me daniel
get a structural engineer to look at it,the only time lime is used is in bricklaying mortars, or sometimes to soak up wet mud on a particularly muddy site
i really dont understand what they were doing
got a picture? that may be helpful

Another great line from tonight,
When I showed that near the entrance (Where we will drive the most) there was only 2 cm of hardcore/whatever they have laid and you could see the mud.

He claimed it was not mud. It was hardcore that was a bit dirty.( I could make mud pies out of it)

The hardcore is getting thicker. Last week I was told it was 7 cms. Its now up to 12 cm and getting deeper by the day.

i thought they had laid grey pavers for a minute in the border but then i realised that is the bedding mix
its the queerest looking stuff i have ever seen but it aint right ,should be on 35-50 mm of coarse sand ==>end of as they say
ask them why they didnt use corse sand like the rest of the world?

all i can say is wtf is that i have used very very light coloured sharp sand in the past but thats just too light coloured. do you know where they bought it ?

Those thin bits of block are pretty crap too

"In some parts of Britain and Ireland, a grit or a stone dust (whin dust) is used in place of the more usual grit sand......However, the vast majority of projects are laid using a plain, simple, straightforward grit sand."

This is taken from the main website on block paving-flexible constuction. I suppose some areas may not have easy access to grit sand. So maybee it's ok.

Now didn't somebody mention "Whinstone" or something similar the other day and it was met with blank faces?

when i was an apprentice 30 years ago in birmingham, lime was used all the time to mix with bedding sand. once completed we made a wet slurry of lime and brushed it into the joints of the flags.I was down there a month ago and what was left of the areas were still sound. we also used it in the thunder box to stop the flies etc. those were the days when one of my jobs was to shine every brick and channel in manholes with linseed oil. clerk of works then would condemn anything its a wonder we made two bob.

when i worked on a big shopping centre all the manholes had to be water tested,i.e. filled with water to make sure they didnt leak,the COTW was really anal about polishing benching and such,still thats their job i suppose

Ive used whindust before, and its just like Type1 but with much more fines. Or thats what we call whindust up here

[seanandruby]

i am having to fill all my manholes and pipes with water with over 200 manholes thats a lot of water that has to be lifted in by crane first. imagine filling a load of 225 pipes like that. as you say thats there job
