Hi All

ex council house outside store roof 100mm thick concrete area about 4m x 3 metres

has rasied front and sides (a lip about 25mm high)

Never been felted

Looking at the fibrous paints or other low cost solution

any recommendations


Is there any provision for the rainwater to drain off or does it just
puddle up and stay trapped?
is there a fall?

-- yep slight fall to the back with gutter and downpipe


Having read all the other posts since my reply this am, I would also
recommend the cromapol product or there's another called aquapol, I
think... Check out JJ Roofing supplies or Wedge roofing, but again, it's
not cheap- about £90 a tin retail, £60 trade. For a cheaper way of
remedying it as a trial.... If you can find the crack get a tube of Sika
and use that to fill the joint, it's great stuff.


What else are opposable thumbs for? Get to me at
