IMPORTANT NOTICE

Moladi Building Communities based in South Africa has introduced the Moladi building cast house system to the Nigerian building industry. They argue that with this technology a building can be built within 24hours. They explain the construction process…
 
Existing since 1986, the Moladi technology is an award winning and unique, lightweight, reusable, patented injection moulded formwork system that has been developed to streamline the cumbersome qualities, and the much inefficiency associated with traditional timber and steel formwork as well as other alternative building methods. With the emphasis of the Moladi technology being on quality and efficiency, the Moladi formwork has been specifically designed to benefit the end user with its unique simplicity.

Moladi facilitates the training of local contractors and entrepreneurs to use its technology. The formwork components are produced to the highest quality standards, with an unlimited production capacity. The Moladi formwork is a comprehensive system that is entirely boltless, freestanding, and does not require the need for struts or bracing. Moladi is unique in that it represents the most advanced alternative building solution with a proven track record and years of experience in the construction industry. The injection, that allows for moulded formwork is lightweight and robust, weighing 8kg/m easy transportation and the speedy assembly of components. The precision components are fully interlocking and any dimensional adjustments to the desired structure can be made with little effort. The modular components are assembled into easy to handle panels which are configured into a mould of the desired structure. These panels are joined to form wall configurations of any desired length and height with a wall cavity of either 100mm or 150mm. Once the assembly of the panels are complete, it does not need to be repeated. The formwork panels can be re-used 50 times; making the technology cost effective due to its repetitive application scheme, reducing the cost of construction and transportation significantly. The steel reinforcing, window and door block-outs, conduits and other fittings are positioned prior to the wall cavity being filled with the mortar mix. The result is a wall with a smooth off-shutter finish that does not require any plastering, beam filling or chasing. Once the pre-assembled formwork panels have been removed they can be immediately re-erected on an adjoining site to be used on a repetitive basis; again saving valuable time in the construction process.

Construction Process:
Day 1: Start: 11.00am
Step 1
Formwork is delivered to the site
Area = 74m²
Mass = 550kg
Volume = 4m³
Start the erection of Moladi
Panels are assembled by general labourers to form the mould/kit of the desired house plan

STEP 2
Internal panels are erected
Window frames and block-outs (Win Bloc) are positioned
Mesh and reinforcing details are placed according to engineer specifications
External panels are then erected

STEP 3
Door frames and block-outs (Door Bloc) are positioned
Erection of Moladi completed (4 hours) with only four labourers

STEP 4
Four labourers are needed to manually fill the wall cavity with 3.4m³ of an aerated mortar mixture
The pour is completed (2 hours)
FINISH: 5.00pm

Day 2: Start: 7.00am
Step 1
Formwork is removed
Panel being moved weighs less than 30kg (3.84m² X 8kg/m²) and can immediately be re-erected on the next foundation
Removing the Moladi formwork complete (2 hours)
FINISH: 9.00am

STEP 2
The structure can be painted with a cementitious water based textured paint as soon as Moladi is removed
Oil or water based paint can also be used at a later stage

STEP 3
The walls are 1.5 to 2.0 mPa strong with an ultimate strength of 10 to 20 mPa, achieved in 28 days, depending on the mix design of the mortar (C:W Ratio)
Engineer certified roof is constructed

STEP 4
Final finishing's, such as plumbing and electrical fittings, are completed
The structure is now ready for occupation
