About moladi:
Founded in South Africa in 1986 as a method of building cast in place reinforced monolithic structures. 
The system is removabl, reusable, recycable, lightweight, durable and permanent structures. 
The construction process is a workflow process similar to a vehicle assembly line. Key words here: standarization, simplification, modularization, industrialization.
