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.
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.
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.
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.
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.
