have to say that we always lay the sleepers on a crushed concrete bed, that way its free draining and they last longer.

Ok i have 5 tonnes of type one in the front garden and am picking up a 90 kg vibrating plate at lunch time, any tips on compacting and getting the levels right?

put down a layer 70mm deep and run the plate over it until it cant be compacted anymore (you will know when) and then repeat the process. Good luck

Pull some string lines to the fall and use a dip stick with the finished height of your type one on it, you can raise the line up and off set the mark on the stick accordingly. Place type one in layers and compact to refusal.

I am liking the dip stick idea, only had the afternoon today but got about 70mm all over will set the lines tomorriw then whack it, then put the rest on it and whack again

Well thats the base in and compacted, the last bag was a different consistency to the first 5 so have a bit of a flat spot, will have to make ot up with the bedding layer.

Next weekend i will finally be laying the slabs, so big question is now what consistency should i go for with 25mm sandstone, how wet shod the 6:1 be?

Each layer has his own preference, i tell my labourers i want the mix to fold in the mixer at 2 oclock. Thats how wet i like it but you need to over lay the muck for each stone to hold height. And as a beginner you may find if its too wet and you dant lay it out close to the right level that the water muck will sit high around the stone making a mess but you will get a good bond

ok thanks, I will experiment, I am thinking something like peanut butter, not sure what time that folds!

not actual peanut butter of course, I mean the consistency.

i would go a bit wetter than peanut butter
i like it wet enough that it can stick to my trowel if i swirl it upside down

Got my SBR delivered, am all set to start laying tomorrow, with soggy peanut butter, this is probably a stupid question but I have to ask it otherwise I will be second guessing myself all day!

Should I put plasticiser in as well as the SBR given that its going to be hot tomorrow, or does the SBR also act as a plasticiser as well as improving the bond?

I think after all the advice and reading other threads I am going to do 10 shovel s to 1/2 bag for a strong 5 to 1.
