Advise on repairing old wall before tanking


New Member
Hi, i am in the process of fitting new bathroom (and kitchen) - but discovered some damp, so i've stripped the render off the wall down to brick and treated with Anti Sulphates which really stunk!!...

Now i need to repair the wall and then maybe using the Soverign k11 tanking system as heard good things.

I've attached some pics, as you can see theres a few holes, its c1900 victorian terrace converted around 1980 so guessing i would use some lime / sbr mix and put bricks back into the larger holes etc and then tank on top etc?

Any advise is welcome, trying to take time and do myself to save a bit of £

Change the timbers to lintels if possible, infill with similar bricks to the back ground , I'm reluctant to say dub it out with render , I'm thinking get it flat and sealed with the k11 ,then either dab it with insulation plasterboard or limelight it level

As above. Ya definitely need to sort the timbers. Replace any damaged bricks. Check outside condition too. Make sure nothing is coming through
