All three foundation types are usually constructed out of concrete, but can also use concrete masonry units or insulated concrete forms.
Concrete Masonry Units (CMUs) are hollow, concrete blocks. To create
foundation wall, mortar is used between blocks to hold them together, forming
wall.
Insulated Concrete Forms (ICFs) are made of rigid foam insulation forms (a system of support assemblies, including mold, hardware, and necessary bracing to hold concrete) into which concrete is poured. Once
concrete has gained its full strength,
outside forms,
inside forms, or both are left in place to insulate
wall. ICFs are common in regions in which
local building code requires
foundation to be insulated. Another benefit is that
homeowner or builder is able to finish basement immediately, without adding studs.
