Affordable Modular Housing
WHAT ALL AFRICA HOUSING
HAS TO OFFER
A. Polystyrene - ECO friendly building system
•
All Africa Housing has developed it’s own unique Polysterene ECO friendly building system. Not only more affordable, but quicker to build.
Excellent thermal values, and fire rating.
•
We do not dictate by telling what we build, but what our clients’ requirements would be for us to build.
•
Suitable for, residential, schools, colleges, lodges etc.
•
A structure designed primarily for residential occupancy, designed and constructed to a state or national model code, which is
manufactured in one or more sections in a factory for installation on a permanent foundation at its final location .
B. DIY - ECO friendly building system
•
Our Park homes are pre-manufactured, assembled, and commissioned in our factory.
•
The parkhomes have a very strong chassis system that allows the park homes to be
loaded on trucks and offloaded on site again.
•
Our size range from a 6m to 12m lengths and 3m to 3.4m wide.
•
All park homes can be joint together to create a wider building.
•
This system is ideal for when there is no time on site to do the construction.
WHAT MODULAR IS NOT
• A movable or portable
dwelling built on a Frame
or water raft, connected to
utilities, designed without
a permanent foundation,
and intended for yearround living
DIY
Quick installation.
• Can be used for temporary and permanent
accommodation.
• Magnesium oxide floor boards. Fire proof and durable.
• Very light 0.8mm galvanized lip channel steel.
• Unlimited floor space can be designed accordingly
• Mild Steel chassis are also available on request.
• Save on labour and installation.
• Lifetime durability
Product Specifications
1. Insulated Panels
A. Fluted and flat Panels are used for wall construction. All panels are tung and groove. Our
panels are made of 0.5mm colored chromadek steel sheeting illuminated with Expanded
polystyrene. Generally a 75mm wall panel is used, other size thickness are available
depending on the requirement of certain applications. Our fluted panel is 20% stronger than
our flat panels.
B. IBR Wide span panel is used for our African and modern style building method and for
large open structures like churches or Canteens. The IBR wide span panel is corrugated on
one side with colored chromadek steel bonded on expanded polystyrene and on the other
side that acts like a ceiling is also bonded with a flat or fluted white chromadek steel.
C. Magnesium oxide panels are manufactured to be used in buildings to create a mortar
finish. The panels are energy efficient. Generally a 75mm to 100mm panel is used. The
panel consist of 10mm MGO board laminated on both sides of a expanded polystyrene
sheet. The male edge has a chromadek steel edge for strength. Once all panels are erected
and the construction is completed can the panels be sealed on the joints and painted on site.
For a more executive look a rhinolite with a pattern can be applied before painting

Extremely ECO friendly
Expanded polystyrene (EPS) building systems
•
With the growth of the South African construction
industry it has been realised that alternatives to the
tradition of brick and mortar are going to have to be
used to enable the building demand to be met.
•
Expanded polystyrene (EPS) building systems are
commonplace in the rest of the world primarily
because of EPS's thermal insulation properties and
light weight.
•
The Polyblock system is based on proven technology
used internationally for the past 35 years.
•
Polyblock is a hollow EPS building block which acts
as a permanent formwork for a reinforced concrete
infill and is used for building houses, perimeter and
retaining walls, infill panels for steel frame
construction, agricultural buildings and high rise
developments.
•
The block stays in place acting as a thermal insulator
for the building.
•
The system is finished by using a propriety EPS
plaster - Polyplast.
Popular and effective products / processes
LIGHTWEIGHT STEEL
TRUSSES
RAFT FOUNDATION WITH
STARTER BARS
•
Raft foundation is a thick concrete slab reinforced with
steel which covers the entire contact area of the structure
like a thick floor.
•
Sometimes area covered by raft may be greater than the
contact area depending on the bearing capacity of the
soil underneath.
•
The reinforcing bars runs normal to each other in both
top and bottom layers of steel reinforcement

Planning and Completion
WHAT TO CONSIDER
ON-SITE COMPLETION
• Site Conditions
•
Foundation and site works
• Site Access
•
Electric meter base (and disconnect)
• Single Home or Multi-home subdivision
•
HVAC system installation (mfg specific)
• Stand orientation and design relationship
•
Condensing unit/air handler electric
• Is time a critical consideration
•
Drain and vent line completion
• Do I have green requirements
•
Matching wall finishing
• When surrounding features complicate the set
process (trees, power lines, adjacent structures)
•
Connection to services (water/waste/electric)
• When additional site work is not required to support
modular handling
• Time is money
