I have some three week old Kiln dried sand which I want to use on my drive restoration. I note that the bags have been damaged. (Kids and bikes me thinks). but the sand is dry and runs freely and there are no lumps or any sign whatever of moisture. (The bags are in a very dry garage attached to my house).
Is this sand OK to use, especially as I am going to use with Resiblock 22 as my drive slopes and every year the majority of the sand washes out - even if sealed with water based sealant. :O

for what it costs mate buy another bag once the bag is open it starts to swell use the old bag around the edges or where there is large gaps 8mm and above

Thanks, sounds good sense but I still wonder if the sand is bagged "hermetically" so it does not absorb any water at all or if this is not that important.
I went into a branch of a national distributer and saw almost every bag of Kiln Dried sand had burst and it is this that aroused my curiousity as to how important the exposure to the atmosphere is.
Anyway, thanks for the immediate solution!

you can always re dry it although this is a pain
spread it over the drive on a hot sunny day and leave for 2-3 hours
then sweep away!!
i should be in womans weekly with rubbish tips like this but it works
cheers tony :laugh:

Most helpful as you've convinced me that dry is not to be taken as chemically dry.
Furthermore, I went back to the national chain of DIY providers this morning and found their stock of Kiln dried sand was outside the building in bags, many of which were broken, and simply covered with a further sheet of polythene, (which didn't cover the lot!)
It was raining and the forcast is for a rainfall alert. So much for dryness. Interestingly, their builders sand was just under cover and in what appeared to bee stronger bags.
I will work on the basis that, "If it runs like an hour glass, its dry"
Thanks
