The EarthCo Megablock Process is a new construction delivery system that combines an on-site manufacturing process with a synchronized mechanical placement process. Our process is designed to maximize the efficient use of time, energy, labor and resources. The result is transformational --- sustainable, energy efficient, superior performing structures at twice the speed and 1/2 the cost for similar performance. The EarthCo Megablock process features a patented mobile manufacturing plant that compresses man's most abundant and sustainable resource --- local earthen material (free if located onsite) into Giant Compressed Earth Block (GCEB) which are immediately placed into a wall system. Common construction equipment is used to power a special lifting device and lift, carry, and place EarthCo Megablocks. Our giant building blocks (>1ton) and mechanical placement results in huge production potential and lower costs. EarthCo Megablock walls measure 18" thick or thicker and provide excellent thermal mass which can result is savings of up to 90% on home heating and cooling bills while providing superior protection from severe weather events, earthquakes, wildfires, and gunfire. The EarthCo Megablock process is believed to have the lowest embodied energy costs and best life cycle assessment costs of any construction delivery system worldwide.
