The inefficiencies of moulding a brick or block in a mould
then tasking an artisan to lay them. Then chase the walls for water and electrical services. Then relying on another artisan to plaster the walls. Depending on the skills and ability of artisans to produce a house vs. casting a house in a mould employing unskilled workers – eliminating the need to chase and plaster, in a day, at a known cost.

Molding or Moulding Process:
moladi Construction Process - Video Link
Molding or moulding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern, a model or formwork of the final object.
A mold or mould is a hollowed-out block (cavity) that is filled with a liquid or pliable material such as plastic, glass, metal, ceramic raw material or mortar (sand and cement). The liquid hardens or sets inside the mold, adopting its shape. A mold is the counterpart to a cast.

plastic formwork (mold or mould) is removed the day after casting.
A disruptive innovation is
an innovation that helps create a new market and value network, and
eventually disrupts an existing market and value network (over a few years or
decades), displacing an earlier technology.

Modern building
methods using modern building materials:
moladi Construction System aims to address the challenge by providing a scalable, low-tech and low-skilled affordable building solution using in-situ casting. Founded in 1986 by South African social entrepreneur Hennie Botes, the company aims to replace the classic brick-and-mortar construction with an easier method: using a patented lightweight, removable and re-usable plastic injection moulded formwork system that is filled with fast setting aerated mortar to cast entire houses on-site. The process is deliberately designed to be labour intensive to boost local employment and local production without requiring prior construction experience or skills. The moladi construction process mostly uses local supplies apart from the reusable formwork and a special additive to aerate the mortar (concrete without stone) to reduce the density, thereby enhancing the thermal properties of the structure. The other function of the additive is to water proof the wall and enhance the flow ability of the mortar within the formwork eliminating the need to vibrate.
Through creative engineering and
sophisticated manufacturing, moladi
aims to advance living standards and spaces affordably. moladi is an advanced building technology that utilises an innovative re-usable plastic formwork system to reduce the required skills to produce quality affordable homes and other structures that are socially acceptable by speeding up delivery and thus
reducing cost. By emulating the methodology of the automotive assembly line, moladi implements the principles applied by Henry Ford; reducing cost by increasing production output by de-skilling the production operation, making homes affordable.

The advantage that moladi brings to the
“production process” is that the process can measured and maintained, ensuring
consistent speed and quality within budget.
It all comes down to efficiency of producing a cost effective, socially acceptable wall for people (knock test), then fixing all the other components, like door, windows, roof, ceiling, bathroom fixtures etc., onto the "chassis" (the wall). So in reality, who can produce a wall on a stand the quickest, and millions of them? We simply use a cost per square meter of a wall (chassis) on a foundation (in position), ready for "assembly" as a yardstick of efficiency. This is method compares "Apples to Apples"?.

Conventional brick and mortar construction:
- How many bricks or blocks are laid per day?
- Are the quantity of bricks or blocks laid per day the same for every day of the week?
- What happens when the bricklayer does not come to work?
- Is the dagha (mortar) mix to lay the bricks or blocks consistent?
- How many bricks or blocks are wasted or broken or stolen?
- Are walls straight plumb and square?
- How long to chase for electricity piping?
- How long to chase for water piping?
- How long does it take to do beam filling?
- How long does it take to plaster window reveals?
- Is plaster thickness consistent or does it vary?
- Is the plaster mix consistent?
- Any rework?
- Rubble to clear?
This leads to the question: Are the inefficiencies of the brick and mortar construction process making homes unaffordable for most?
“If you can't measure it, you can't manage it.” - Peter Drucker
By applying moladi the above variables
are excluded from the equation.
moladi Construction Process:
moladi Construction Process:
- Erecting the formwork is constant.
- No stays
- No propping
- No consumables
- Formwork holds a constant precise volume.
- Mortar a known cost.
- Mortar is a known consistent compressive strength.
- Reinforcing a known weight/cost.
- Time to position and bind reinforcing constant.
- Filling the formwork is consistent.
- Removing the formwork is constant.
- Labour is not skilled.
The above description is exactly the same cycle as the plastic injection moulding process. Therefore we refer to this process as the moladi Injection Moulded Construction System - Fourth Industrial Revolution | Housing Construction
Injection Moulding Process:
Injection Moulding Process:
Mould closes – Material injected – Cools – Ejects the finished component. A known cycle time at a known cost.
Speed reduces cost - A
“lean construction” principal.
Erect Formwork (Clamp) - Fill Formwork (Inject) - Mortar Sets (Cools) - Remove Formwork (Eject)
Lean Construction - Lean Production:
One of the important principles under a lean production paradigm is termed ‘lean assembly’. This refers to simplifying the process of assembly through industrialisation, modularisations, standardisation, and continuous flow processes. The reduction of operations required for a production process means less chance of the occurrence of errors, waste and rework.
This follows from the same logic that the fewer the number of operations, the higher the quality of the product and a predictive timeline, resulting in cost savings. moladi formwork system provides and assists with the full range of requirements involved in the transfer and use of a proven low-cost construction technology.
Jobs Food through Shelter:
moladi
supplies technology and supports transfer of know-how to empower individuals to
achieve self-worth, by meaningful action to raise those at the “bottom of the
pyramid” to a higher level, supplying a proven technology with an impressive
track record (Est. 1986). This is how moladi
can address the delivery of quality homes in less time, creating jobs by
employing unskilled local labour - developing skills and entrepreneurs.

moladi - A Technology Supplier:
We skill entrepreneurs, contractors,
business owners and construction companies how to “produce” using moladi construction
technologies - “What if we told you the solution to the 25% national
unemployment statistic (36 %youth unemployment) and the million-plus housing
backlog was already in our back yard? And what if we told you jobless,
unskilled South Africans could become entrepreneurs in the house building
sector and be able to build homes in their communities at a fraction of the
cost and in less than a week? What would you say if we told you there is a
company that is not only prepared to certify you, but to empower you too and
give you a market, technology and the opportunity to grow personally and
professionally?" - Link
