    Hey all,

    I posted previously about my project to re-roof and re-render my ancient single skin detached garage.

    I spent the weekend hacking off old render (fun!) and the bottom of the rear wall of the garage is soaking wet.

    Pictures below - this was after I’d lifted the slabs that butted right against the wall.

    my plan is to install a channel drain across the rear wall with 50mm concrete either side. Hopefully that helps disperse surface water.

    I’ve also bought some sika inectocream to try and create a damp proof course (I don’t think one exists in any walls).
    When I was drilling the holes for this tonight - the mortar that came out was really damp to the point of being ‘mud’ in some place. (Again see pics below)

    anything else I should be doing to combat this?

    bit worried about spending a couple of grand on the refurb if there is a fundamental issue that can’t be sorted.

    Thanks!
