I may have had my expansion reasons mixed up...

A guy I know built an epoxy-concrete machine with steel bars at the surface to connect the rails to.
They were flat when casting started but the end result was not.

If you cast EC in a steel tub, it may end up not being part of the construction but just a liner and not a reinforcement.

There are many ways to not do it right. Apart from choosing the best epoxy for deep casting, is good idea to read the documents of the said epoxy and follow them instructions to the letter. best is to call the epoxy manufacturer and speak with them for the most suitable epoxy for the purpose.

Cause at the end of the day they know their stuff and even can mix a custom epoxy for your purpose. I have talked with one company technician and he knew exactly about that situation and explained me the differences between the 3 suitable epoxies they had.

The http://durcrete.de is quite interesting.

What I was aiming for was finding a sweet spot between price/performance and ease of construction given that I only have not very accurate tools to work with.



The Durcrete site has some vibration damping data available and a demo:

Definitely they are the most promising ones. I remember spending 2 weeks of my free time / when i had one/ browsing and searching. And thinking of it its not at all so expensive as it could be with the epoxy. I had somewhere their offer and it was relatively cheap. from their site:
