Broken line segments still generates a surface area?

[MLUY]

Hello There !,
I am trying to extrude attached surface area into a solid to do some volume calculations (merge / subtract operations) But I am getting a lot of errors on the edges of my extruded shape. I am pretty sure it has to do with the fact that the border edges are broken into segments whilst there are no triangulation lines. How can Sketchup still generate a surface area and how do I get rid of this (without doing it manually?) and generate a proper surface to extrude?
Thanks
Michiel

Better if you can send your skp (save as version 6) for a more large audience!

Thanks, I just uploaded the file.

You can resize your object by 1000
then use CleanUp by Thomthom it finds many problems and repears
Then Joint PushPull by Fredo for give a thickness

Then solid Solver by Tig

But despit of that seems there are always problems, too little surfaces, maybe intersect faces etc...

where does this object come from? An unfolding one ?...

Thanks Piloe, its the result of an intersection with two solids from a topographic survey but its a complete mess. I just spend 3 hours to do it manually and finally managed to get a clean solid (joint push pull V) I guess there is no easy way when you get a shape like this
