Today was spent cutting the two sheets of reinforcing mesh fabric to fit the floor.  I have to say that handling these mesh sheets is probably the most ANNOYING thing ever...if there is a potential object to hook onto, sure enough it hooks onto it, including other sheets of mesh!!! Oh well! using the angle grinder and a LOT of care,  I had to make a lot of cuts, cutting to size then removing ends and de-burring sharp edges.  You'll see in the photos the mesh sitting in place cut to size, though I had to remove them again to put the DPM in place.  I did it this way to reduce the possibility of damaging the DPM whilst manoeuvring the mesh sheets or should I say sh*ts!!  Next job was to effectively dam up the doorway ready for the concrete pour  ensuring the concrete stays in the room.  This also meant chopping off 100mm from the height of the existing door to allow the door to open.  Removed the door, cut a section from the top (the circular saw dealt with this like a breeze), realigned the door in the frame and re-screwed the hinges at the new position.
