The blocks are called Perry Blocks. I've seen a few truss arch buildings built on Perry Blocks. Actually, my employer came out and looked at mine and then erected one 200 feet long, 20 feet high and 50 feet wide, open ended on both ends anchored to a Perry Block wall, 2 tiers high on each side.
They store chipped wood in it. One end is processed chips and the other houses a large tub grinder to grind trees into wood chips for their 250 horsepower Hurst Biomass Boiler.
As an aside, mine has never heaved and it's attached to 2x12's. It's never moved at all and it freezes to 48" below grade here in the winter.
Interestingly, mine has no source of heat inside but the sand inside never freezes. There is more than enough radiant convection through the translucent center section to keep it quite comfortable inside all winter.
I fully expect mine to last the full 15 years the warranty covers the cover and possibly more. It's been 4 years now and the cover shows no weathering whatsoever.
