End grain floors

[low_48]

All the factory floors at Caterpillar used to be end grain blocks. They were all sealed with tar. Not home friendly. When I worked on those floors, I can remember machine coolant spills that would buckle the floor. They scooped out the blocks, laid in new block, then poured on the tar. Talk about bad smell!
I once saw an end grain block floor laid on This Old House. They used powdered cork and shellac as the grout. The cork would have the give for wood expansion.
Here's a great pic of a cordwood house wall. Maybe it'll give you some ideas. Stupid long links.

Stupid long links.

This is how you shorten them.

Much shorter link wouldn't you say?
