Only the footers were placed utilizing premixed concrete in trucks. A startup called Energy Vault thinks it has a viable alternative to pumped-hydro: Instead of using water and dams, the startup uses concrete blocks and cranes. Stacked concrete block walls are unreinforced walls, which means that they have a specific and abrupt yield point, rather than a yield range. We estimate we have put into place well over 100,000 pounds of block and cement, all of it mixed in a small cement mixer and placed into the cores with small hand scoops.

Slight imperfections in blocks sometimes cause gaps or need shims or trimmed to fit. A fret of parts laser-cut from 3mm MDF to make stacks of concrete or stone blocks.The filled cores hold daytime heat, keeping room temperature more even at night as heat is radiated back into the house.Easy to stack and build by one or two persons.Stronger than conventional block and mortar construction technique.It is installed and squared, then secured to the footing or foundation slab with lag bolts. (See the page for Passive Annual Heat Storage) The EZ Stack Blocks System Consists of Four Major Components Metal Starter Strip: This Optional metal strip is formed to mate with the bottom side of the linear and corner blocks. We are using an "umbrella insulation" on top of the ground and out 20 feet around the structure. Five blocks, U-shape, being two blocks high on attack face. There is no insulation on the outside wall of this particular structure. Generic stackable concrete blocks in, each 1250kg with dimensions H400mm x W1600mm x D800mm.
