    Default Roof terrace

    I have a 50m2 roof terrasse. The grout has become permeable and rainwater is leaking into the cellar below (this is because the original builder "forgot" to put any sealant on top of the concrete base??).
    I can't remove all the tiles and start from scratch, so I simply need to renew the grout. Is it favourite to remove ALL the old grout? What is the best way of doing this? What is the most effective water resistant grout on the market? Thankyou.

    thanks but afraid this is not possible; 50m2 is a a big area and the thickness of the cement between tile and terrasse floor is almost 15cm.
    However, if you fancy quoting for the job I can send you a photo?

    thats not a good move as it will creat more issues and finding a waterproof membrane that will garantee over tiles will be hard you may have weight probs


    job realy needs to be viewed but the only grout that is waterproof would be epoxy but the job needs to be seen by a qualified tiler to make the call on weather it can be done and i recomend epoxy be installed by a tradie hope this helps

    if the substrate has been soaked and all the grout is cracking and letting in water to the point its coming through to the cellar below re grouting will not solve this issue i would say it needs to come up you may also have to sort the substrate again

    Grout isn't waterproof. Water will just soak through it. So your problem isn't the tiles, or the grout, it's the substrate behind all that.

    You really do need to pull the lot up, then waterproof the substrate, then re-tile if you want to just from an aesthetics point of view if it you want to see tile there.

    Re-grouting would just be a waste of time and money. I don't think you'd get any professional tiler suggesting you should re-grout to solve the problem.

    If the tiles are well and truly solid then you can waterproof the surface and re-tile... my recommendation would a Tanking membrane like Ditra.

    But you will also need to prevent any water ingress at the sides/edges as well..

    This is hard to say without actually seeing the lay out etc at face value..

    where abouts are you..?

    Would an epoxy grout not sort it?

    Depends on how wet the substrate is.. Ditra would allow moisture to vaporise over time.

    And provide a 100% true tanking.
