Those new buildings by entrance to Humane Society were apparently built using this system. They are claiming a 1000 sq foot cottage, hand you the keys, can be built for around $80k. Exceeds building codes, green construction, high R values.. When something seems too good to be true though I naturally keep skeptical
They were at the Housing Expo as was another distributor with a similar product, though I thought Gigacrete had a better product, though can't remember why now. I'd have to look at my brochures.
But, those concrete blocks are so 20th century, so time for improved materials.
That, if true, would also be quite a savings over traditional concrete block building.
Their model caught my eye as it was going up, because it was clear they weren't using concrete blocks - too white, and indeed looked like Styrofoam reinforced with rebar. Lot of interest at Expo.
It is polystyrene with steel studs. Then coated in their stucco/concrete inside and out. No Portland cement. Uses coal ash from power plants. I'm going to look more into it.
