waterproofing a flat concrete roof
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
Is there any provision for the rainwater to drain off or does it just
puddle up and stay trapped?
is there a fall?
What else are opposable thumbs for? Get to me at
