Is there concern that the rubber will get eaten/deteriorated away over time by nature or chemicals? Or any concern over Teflon cracking from vertical forces?

Teflon is NOT the best choice. Research has shown HDPE on various materials for the bearing plate (including marble, which unfortunately is also soft and fragile) is superior to PTFE (AKA Teflon™).

Earthquakes can also have a significant vertical component (P-waves = lateral, S-waves = vertical) which can destroy a build not yet damaged by the lateral dynamics. The S-waves travel more slowly from the hypocenter and arrive slightly later at the surface, and can typically cause "pancake collapse". This excellent system in the video would need to be significantly modified as to dissipate the enormous amounts of vertical energy/acceleration released during such a quake. I believe the Japanese have already developed such systems, but they are not so elegant or cost conscious as the system shown here, as far as I'm aware.

"teflon coated"?!? One little problem with that material choice: PTFE (AKA Teflon™) cold-flows (deforms) under pressure! Using glass or other fibers to reinforce PTFE reduces pressure deformation of PTFE, but then the reinforcing fibers abrade the bearing plate, which must remain smooth for good operation. Using very thin layers of PTFE eliminates the cold-flow problem but requires frequent replacement of the bearing surfaces. And for everyone wondering why springs aren't used instead of the laminated rubber devices: springs allow too much vertical motion, which increases the risk of service connections (like gas lines) being broken.

Well i take it it's completely protected as in enclosed and waterproofed so that the water cannot get inside... it's not open air as we see here this is for demonstration how it works... And I'm sure thay rubber is also replaceable after an earthquake or after couple of years (as rubber degrades over time) and is maintained every couple years... But this sure is the best quake proofed tech so far and I don't know why investors cheap put on this tech. It should be mandatory. Probably none of the buildings wouldn't be toppled in turkey if they had this system for buildings.

@@mr_hary i do not think that this can function properly, i do not understand why the teflon is there, maybe like a brake to minimize horizontal vibrations, but there i do not see any vertical shock absorbent. The best Base Isolation System made until now which all humanity know is a cheap to product, simple made, low maintenance or zero maintenance, and that is a Seismic Isolation Base with Laminated Rubber and Lead Core. They can be manufactured to withstand 5 tons up to 200 tons under a single buildings pillar. Remember, a wider Isolation Base with Laminated Rubber and Lead Core is = the better are chances to withstand, and higher the Isolation Base with Laminated Rubber and Lead Core is - there will be less vibrations. For homes is enough 50 cm up to 100 cm high and 50 cm up to 100 cm width (diameter) under every cement pillar of the building. With Isolation Base with Laminated Rubber and Lead Core homes, buildings, bridges and similar are full protected. Research for yourself before you decide something. Isolation Base with Laminated Rubber and Lead Core are cheap, but once are mounted - there is no needed any maintenance. You can not mount them after you have build the house. How is shown on this video the system which mover horizontally around upper a teflon, i thing is worse than should be. Only Isolation Base with Laminated Rubber and Lead Core inside (in the center of) the rubber. Lead core will prevent the building from horizontal collapse, but the rubber will absorb the shock. Lead is soft and bends on all sides, but can not be pressed vertically. First you need to know exactly how much will weight the building before deciding which size of Isolation Base with Laminated Rubber and Lead Core you will use.
