The moladi construction system strives to change the way homes are built. They create entrepreneurs who employ the unemployed to produce homes and other structures in situ.
The multi-award winning moladi construction system was founded in South Africa in 1986 as a method of building cast-in-place reinforced monolithic structures. The moladi technology was developed as a means to alleviate the cumbersome and costly aspects associated with conventional construction methods without compromising the quality or integrity of the structure.
The moladi system uses a removable, reusable, recyclable and lightweight plastic formwork mould, which is filled with a South African Bureau of Standards approved and Agrément Certified aerated mortar to form the wall structure of a house in as little as one day. Each set of moladi formwork panels can be re-used 50 times, making the technology cost effective. It reduces the cost of construction and transportation significantly. The moladi system produces durable and permanent structures, which have been subject to numerous tests and independent reports. The process involves a number of smaller components which are assembled into larger, lightweight panels that are configured into a mould which forms a house of any desired size and design. The engineer-specified steel reinforcing bars, window and door block-outs, conduits, service pipes and other fittings are positioned within the 150mm or 100mm wall cavity, which is then filled with a specially formulated and project-specific lightweight mortar. The mortar consists of the local river sand, cement, water, and a harmless cement admixture to form all the walls of the house simultaneously. The moladi plastic formwork panels are then removed the following morning and immediately re-erected onto an adjoining site.
The result is a wall with a smooth, off-shutter finish that does not require any plastering, beam filling or chasing and generates no waste. The walls are then painted, the roof erected and windows and doors are installed to complete the house. The aim is to produce homes in a production assembly line process, thereby reducing waste and cost by speeding up the delivery of completed structures.
