I am taking over a barn conversion as some of you know and am concerned about the state of the drainage work already done.
I have spoken to Wavin, maker of Osma products, and it has said the drainage work obviously needs to be redone to a higher standard.
I only know of Osma but I am sure there must be some other substantial firms involved in the manufacture of plastic drainage pipes.
Can you let us know who the other big players are in this field?
I want advice from as many techinical departments as possible so I have a huge piece of concrete to whack around the useless previous contractor's head!
