    Hi. My driveway (approx 100 sqm) was laid with calcaire around 8 years ago … and is looking dull/dirty. Thinking about a refresh. Would it be best to lift calcaire and lay fresh (if so roughly how much would be needed?). Or can the old stones be cleaned up a bit (bleach solution?) and topped up (again what quantity would you suggest)? Many thanks

    We have had several  driveway refurbs over the years.

    It has always been, top surface scraped off and levelled with a mini-pelle, the subsurface compacted with a wacker and then the top surface replaced with new granite chippings.

    Have you considered pressure cleaning it with something like this?

    The round object is an attachment that cleans outside surfaces, eg concrete. stone patios etc.

    I used mine today!

    Its designed for solid surfaces but does such a good job of containing any loose debris like the muck between my paviours that the OP has nothing to lose by giving it a try, unless the surface is very well sealed the outer brush wont glide on a cushion of water and will hang up on the loose stone I foresee.

    To the OP regarding bleach.

    I used neat swimming pool bleach on all the areas where the moss had become tenacious black lichens which resisted everything else including the karcher and was amazed by the results, just spray on and all the black paviours became red again and all the black crepi became ton pierre again without even rinsing.

    If you can find a pulverisateur that will work consistently without blocking or dribbling then thats the best way, I had to use a watering can and broom, fine for paviours but not for rolled calcaire.

    Don’t talk to me about driveways – ours is a complete swamp at the moment :eek: . With deep ridges up and down.
    But as fittersmate said, we’ve been advised to first scrape off surface mud then level off before dong anything else.
    Hopefully we’re having some sunny weather next week.
