Every film below is footage from LCM projects and equipment: a house cast inside Stay-In-Place formwork, foam concrete pumped into moulds, blocks and screeds produced on site, and the density and strength checks that hold the process together.
Featured film · lightweightconcrete
A complete house structure cast with lightweight cellular concrete inside Stay-In-Place formwork, without columns, beams or brickwork. The clearest single demonstration of how the method comes together on site.
