Moladi reduces high costs of conventional building techniques through new technology

Reducing the cost of affordable housing

Addressing the housing shortage: If the "horse and carriage" transport system is to slow getting people from A to B then it's time for the "Model T" to come to the rescue.

"We can't solve problems by using the same kind of thinking we used when we created them." - Albert Einstein. Old technology has created the backlog - new technology can solve the problem.

Albert Einstein also said “Insanity: doing the same thing over and over again and expecting different results.”

Is it not time for change?

Africa is a rapidly urbanising continent, which according to the UN Habitat, is increasing at a rate of 230,000 people who are moving into cities across Africa each week. Currently, sub-Saharan Africa alone has an estimated housing deficit of 30 million units and every year, the backlog of houses across Africa’s 54 countries collectively increases by 4 million houses. With the population of the African continent expected to reach a staggering 2 billion people by 2050, almost twice the population number estimated in 2010, it is a stark reality that every year, there will be more and more people needing homes, over and above the current demand.

There is no doubt that the challenge facing the continent is a colossus, but the question is, whether conventional building methods are able to cope with the ever-increasing demand for quality homes.

reduce cost of construction

Throughout history, man has become more sophisticated through technology; made improvements on existing standards and norms, which have ultimately been determined and developed according to the needs of the people. Perhaps the advances and progresses in communication and transportation during the past two centuries are the most evident of such improvement enjoyed by civilization. However, even though the need for housing has always been a fundamental requirement to sustain one’s health and welfare, the advances in this area have been somewhat meagre in comparison. The brick and mortar method of construction was recorded as early as 1458 B.C, which means that very little has changed in terms of building structures over a period of almost 3.5 millennia. With the demand and requirement currently facing us as Africans, we cannot expect to resolve the housing crisis in our age with a technique developed for the requirements of society 3468 years ago.

affordable housing low cost

One such innovation is the award-winning Moladi Building System, which looks at incorporating green technology and sustainability to provide the best solution to address the six key challenges that hinder the successful implementation of low-cost housing projects in Africa; namely, lack of sufficient funds, shortage of skilled labourers, lack of resources, work flow control, time constraints and wastage. The Moladi construction system was founded in South Africa during 1986, and has been in successful operation for the past 31 years. Moladi’s founder and designer, Hennie Botes, developed the innovative building technology as a means to alleviate many of the cumbersome and costly aspects associated with conventional construction methods without compromising on the quality or integrity of the structure. According to Botes, “Moladi looks at what has to be achieved now and builds on the knowledge and expertise of yesterday in order to develop sound methods to exceed the needs and expectations of ordinary people.”

Need to build a house quickly? Or build a lot of houses quickly to shelter a growing population?

The moladi plastic mould formwork is filled with cement and sand, with plumbing, electricity, window, and door frames placed "between the formwork."

The shell of the house is ready overnight.

The Moladi building system involves the use of a unique removable, reusable, recyclable and lightweight plastic formwork mould which is filled with an aerated SABS (South African Bureau of Standards) approved mortar to form the wall structure of a house in only one day. The process involves the assembly of a temporary plastic formwork mould the size of the designed house with all the electrical services plumbing and steel reinforcing located within the wall structure which is then filled with a specially formulated mortar mix to form all the walls of the house simultaneously.

ABSA NHBRC AWARD

The result is a fast track cost effective and transferable construction technology that is amortized over 50 re-uses, which reduces the cost of construction and transportation significantly. This also facilitates the possibility for many in situ structures to be built in just one day. It is essentially the simplicity of its design and performance that contributes to the affordability of Moladi homes which are roughly 30% to 50% less than similar structures built using the traditional brick and mortar method.

Affordable homes cheap

The Moladi method of construction, using it's patented plastic formwork, has been designed to efficiently produce structures which have a long life, are durable and adaptable; homes which are considerate of the environmental impact as well as the needs of the home owner. The speed, affordability, quality, adaptability, ease of use, the use of sustainable local materials and the opportunity created to facilitate sweat equity are key advantages that would greatly improve the efficiency with which the world addresses the problems relating to the world’s poor, homeless and unskilled communities.

    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.

    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.

    Lightweight Formwork Building System

    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.

  • How to get South Africa WORKING

    How to get South Africa WORKING

     A "TOOL" to get the unemployed working - Fight unemployment, hunger and crime through housing

    The backlog for Affordable Housing in South Africa are in the millions. The main culprit in increased cost and affordability is "skilled labour*. The lack of artisans in the construction trade continuously escalates due to the fact that there are no new "apprentices" enrolling. Bricklayers and plasterers are only two of the key artisans that effect the cost of building.

    moladi has embarked on developing technology primarily to reduce the dependence on skilled labour in order to reduce cost of construction, and also to increase production quality consistently eliminating costly rework.

    Although moladi formwork technology is primarily a manufacturer of a re-useable machine made patented formwork system that allows walls to be cast stronger faster for less, the principal focus is on the delivery of the “whole house”. A house consists of many components and the” assembly process” needs to be project managed in its entirety. That means windows, doors, roof, bath, toilet, paint, ceiling, glass, electrical hardware, etc. etc. needs to be planned ordered and supplied in order to avoid a “bottle neck” that would stop production creating “waste” resulting in an increase in cost. This in turn makes the product, the home, unaffordable to the majority of people.

    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 #plasticformwork 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. #moladi

    Many people believe that if a house is produced, we have a customer. But, in Africa (and in the rest of the World) we need to create jobs for the customer in order for them to earn money, before they can actually buy the product. So, it is no use producing a house in a factory and trying to sell it to someone that doesn’t have an income or a job. Our focus and passion is to uplift the community by creating job opportunities producing homes"

  • Slag use in building system offers multiple benefits

    Alternative construction system company Moladi has developed a means of incorporating mine slag into its Moladi mix, offering mining companies a viable method for recycling their waste material and reducing construction costs when developing mine-site accommodation.

    Moladi founder and CEO Hennie Botes explains that its cement admixture is poured into plastic moulds to form walls. “Using slag instead of sand in the mortar will result in substantial cost savings for mines during the construction of housing units and other site buildings.”

    Further, he notes that, with mines having problems disposing of mine slag, this solution will enable mines to use their waste material to build infrastructure.

    Business consultancy MJC Business Consulting director Marius Lotter adds that, traditionally, mines made use of conventional building methods to construct the various site buildings. However, he suggests that a lack of quality management, logistical challenges, rigid deadlines, theft as well as excessive costs – including those relating to the use and rental of various types of heavy machinery, the contracting of a skilled labour force and the use of labour intensive methods – have resulted in mines looking to alternative building technologies.

    Lotter notes that the Moladi system not only addresses most of the aforementioned issues but it also creates jobs. This assists mining companies with the legal obligation to, firstly, provide adequate housing and living conditions for staff and, secondly, “facilitate economic linkages to sectors other than mining” – which are the requirements in the 2010 Social and Labour Plan Guideline published by the Department of Mineral Resources.

    Lotter adds that Moladi has been successful in implementing its entry strategy for the mining industry and it “foresees that as many as 150 houses will be completed in 2017”.

    The company is also set to supply 150 staff accommodation units at an Mpumalanga project, which has already been approved, and is awaiting the approval of 22 000 units to accommodate staff at another mining project.

    Global Acclaim
    The company was featured in a World Economic Forum report called ‘The Future of Construction’, published in January, which forms part of a multiyear global economic initiative to guide and support the engineering and construction industry.

    The report notes that Moladi has an advantage over other affordable housing technologies, particularly those using prefabricated building components, because developing countries have notoriously inadequate road infrastructure, which makes transporting fully prefabricated units unviable and could result in the damage of prefabricated components. As Moladi’s system involves the use of lightweight plastic formwork, which is easily transported, it is unlikely to be damaged, regardless of road conditions.

    The system’s formwork is assembled by clipping together a set of injection-moulded, 30 cm × 10 cm × 20 cm plastic panels that are removable, reusable and recyclable. With this system, a building can be constructed in as little as two days.

    The formwork panels are assembled on the first day. Window and door frames, as well as piping and wiring are positioned within the wall cavity before the mould is filled with the Moladi mix.

    To illustrate the speed of the process, Botes explains that constructing a 40 m² house takes a team of 18 workers about four hours: two hours to erect the formwork and another two hours to pour the mortar.

    On the second day, the formwork is removed, the walls are painted with a cementitious water-based paint and the lighting and sanitary equipment are installed.

    The entire process can be monitored by one Moladi supervisor who provides on-site training and assistance to local workers with no prior construction experience or special construction skills.

    Moladi’s system is generally associated with small affordable housing units, but it can be applied to various infrastructure assets, including schools, hospitals or courthouses, site offices and multistorey buildings.

    Its main advantages are the speed and ease of production, the lower costs and reduced environmental impact, the quality of the end product and a localised supply chain that benefits local communities.

    The cast walls have a strength of between 7 N/mm² and 15 N/mm² – which is significantly stronger than traditional structures.

    The technology has undergone extensive testing and received certification from several African building and standards authorities, including the South African Bureau of Standards and the Tanzania Bureau of Standards. The structures are also reported to be “very earthquake resistant” according to tests conducted by the University of Panama.

    The system has been used to construct several thousand units in 20 countries in Africa, including South Africa, Nigeria and Tanzania. It has also been used in Sri Lanka, Mexico and Panama.

    Moladi is reportedly preparing to expand its footprint to include the UK and other industrialised countries that have a shortage of affordable housing. The report noted that one of the virtues of the Moladi system is that it can be easily adapted to local building codes and conditions by integrating the required reinforcing structures into the cast.

    It concludes that the system is limited to single- or two-storey buildings, but Moladi is working with engineers to upgrade its construction processes and mortar to qualify the use of its system for multistorey buildings.
