We have a brick outhouse with a cast concrete roof, it has leaked for years, I have finally managed to gain access to where the leak is.
There are 2 cracks, about 150mm long 20mm wide and less than 10mm deep, they are not cracks in the concrete but look like the wire that was used for reinforcing has rotted away and damaged the concrete.
House is about 70 years old.
Best solution?
