Our EIBB machine produces blocks of precision height and width with an adjustable length. The blocks are tongue- in-groove and can be dry stacked or used with mortar. Our machine can also be manufactured to produce "traditional" blocks without the tongue-in-groove. The machine weighs under 2,000 pounds and can be towed behind a truck or SUV and can be easily moved around a small or large building site. It takes roughly 4,300 blocks to build a 1,200-square foot house. Our machine produces 2 blocks per minute and these blocks meet all standards for load-bearing capacity and strength.
