    Hi
    I have a summerhouse on a concrete base that recently had patio stones laid around it and so the summerhouse is now below the depth of the patio.

    Where the patio meets the summerhouse is a resin bonded grout that I was told was non-porous however its definitely porous! What happens when it rains heavily is the rain soaks through the resin an runs under the summerhouse

    I sealed the slabs (and I thought the resin too) with a patio seal but its still porous - any thoughts what I could use on top of the resin please?

    Water will always find a way to a lower level.

    I think the summer house needs raising.

    if that a problem you could remove the paving joint so the water can escape.
    that would be my answer ,along with cutting a deep groove into the concrete if possible.

    would that help?

    Sounds like a possible - maybe drill some holes though the concrete to allow drainage too? You dont think it would be possible to prevent the water getting down there in the first place somehow?
