hollow blockwork

[philip parkin]

Hi
I am building a base for a log house in the alps in France.
The normal blockwork used for this type of project in France is hollow blockwork with steel rods inserted through the holes and filled with concreate. I have some considerabe experience in using concreate blocks in the UK, However i have never used these hollow blocks. Can anyone offer me some advice? Questions like ,
How do you put a damp corse in as the steel rods and concreate infill go right through to the foundations?

Thanks
Philip

The damp course is laid around the steel Philip. Its virtually inpossible for damp to syphon up what are effectively concrete piers inside the blockwork and when the block are laid half bond, as they should be, the end of each block will sit on a piece of DPC.
