Hi,

I am currently considering laying a simple block paved drive, but however i am unsure on one aspect. I would like to lay key kerb edge restraints either side of my drive, but i am unsure when you should lay them, and what happens when you come to screed the sand. If the kerb unit was 200mm high and i wanted the kerb to be 100mm higher than the blocks once compacted, how would i set up the screed level?

Easy! Lay your kerbs as detailed in the kerbs/edging section of the site, and then lay a soldier course of blocks against the kerb, 100mm down from the top, on a 10:1 grit sand/cement mix. You can then use those soldier courses to screed from, with a notched board, as you prepare the laying course for the rest of the paving.

Does that make sense?

I know some contractors lay the kerbs as an afterthought, but we find that, with no firm haunch, the edges of the pavement can drift during construction, and then you're waiting for the haunching to harden before you can consolidate the paving, whereas, if you lay the kerb first, the backing concrete has set by the time you've laid the rest of the blocks. :)

Thanks alot Tony, that makes really good sense i now hope the driveway will be a success!!
