Personally i think concrete would have a slight dampening affect on vibration. but that also may depend on how thick it is and the mixture.

Thanks for the link.
The video was very informative. At least I have the foundation for the pier right. The presenter said that 1m3 of concrete weighs 1 metric ton, but I think he has got this wrong. 1m3 of concrete would weigh 2000kg give or take a few hundred kg depending on the types of materials used. My footing would weigh well over 4000kg.

Looking at the specs for the Software Bisque pier, it seems they have a very different approach. The slotted holes, not a wide base plate compared to the diameter of the vertical shaft and there are no webs that run from the base plate to the top of the pier.
The only similarity would be the way the mount bolts onto the top plate of the pier.

So the question is, in practice which is the better pier?
To me the Astro Engineering pier looks to be a far better design.

Cheers
