Inflatable concrete constructions

US-based start-up Automatic Construction developed a way to create quick construction using inflatable flexible formwork.

The concept is simple: roll out the reinforced flexible plastic 3D structure, for instance in the shape of a house, fill it with air, then pump concrete into the structure, and wait for it to dry.

Automatic Construction says the process is 1/5th the cost of conventional building methods, and includes reinforcement and waterproofing, in the form of the flexible formwork, which can stay in place. This also provides Passivhaus energy efficiency, according to the company, as it creates an airtight barrier. The process is also much faster, since no scaffolding and other reinforcement is needed. Any type of material can be used to create the houses, as long as it can be pumped, like geopolymer concrete.

Once the structure is pumped full of concrete, facades, windows, doors, etc. can be installed. Plumbing etc. are bolted to the wall and covered with foam insulation, though in the future the company aims to build the mechanicals and chaises into the walls.

Currently, Automatic Construction offers single family and accessory dwelling unit (ADU) homes, though they plan for other structures like commercial and military structures, tunnels, pools and infrastructure in the future, and perhaps even skyscrapers and housing on Mars.
