INSULATED CONCRETE FRAMEWORK
Introduction
Insulated concrete form (ICF) relates to a method where reinforced concrete is made
with thermal insulation to make exterior and interior substrate for roofs, walls and floors that
are usually dry stacked then filled with concrete. Self-build is the act of creating homes for
oneself using a combination of methods including being involved in the actual construction
work or even hiring a contractor. Modern methods of construction include precast flat panel
system, 3D volumetric modulus, flat slab construction, concrete walls and floors, twin wall
technology, precast concrete foundation, insulated concrete form, and concrete wall and
floors (Haefs, 2010). For a self-builder what would be the best method? This report will try
and prove that the insulated concrete form (ICF) of construction is the best modern of
construction for self-builders. Also its merits over the traditional method of construction.
The ICF design
There are things to consider when building using the ICF method and they include:
The ICF walls should not be thicker than metal or wood formed walls as this will affect the
exterior and interior designs. There is a need to preserve interior space by placing moving the
walls outside. Bathrooms and stairwells can be affected if the thickness of the wall varies and
is moved to the interior (Matthews, 2012). There is a need to maintain interior dimensions to
alleviate this worry.
Vents are to be installed in the concrete core or interior wall partition.
Windows and door openings are recommended to be 12 inches or more to ensure a proper
consolidation of concrete and create a structural column.

Headers and lintel designs should be based on product engineer
The ICF building process includes:
The first step involves excavation and site preparation (Panushev, 2014). A solid
foundation forms the basis of any project. Site clearing involves the removal of trees, bushes,
roots and other types of vegetation. Ensure that the ditch markings are well put and dug
properly. Backhoe operators use a centreline or an outer edge as their basis and by knowing
the veneer to be used will show the footing to be dug.
Secondly, form the footings as per the engineer’s requirements. Footings form an
integral part in construction of the foundation. They constitute of concrete plus rebar
reinforcement that has been poured into an excavated trench. Footings usually act as a
support to the foundation mostly in areas with weak soils by prevention of settling. In-ground
footings aren’t usually straight hence you should leave some extra width (Association, 2012).
Footing often spread the load from the structure to the ground.one has to consider frost lines,
moisture control, code compliance, structure loading, and soil type when designing the
foundation.
Thirdly, place the concrete footing forms by finishing the concrete to make a level surface
for the ICF blocks. Formwork involves pouring cement in temporary or permanent moulds.
They are usually assembled on site and stays in place after the concrete has cured.
The fourth step involves stacking the block forms. The first row of the ICF walls
stacks directly on the footing. ICF blocks are usually 4 foot long and 16 inches high but may
vary mostly due to manufacturing styles. A cavity that gives the blocks strength is created
