A traditional foundation is used to support a structure in an area where the ground freezes. A
footing is placed below the frost line and then the walls are added on top. The footing is wider
than the wall, providing extra support at the base of the foundation. A T-shaped foundation is
placed and allowed to cure; second, the walls are constructed; and finally, the slab is poured
between the walls.
The primary purpose of the footer is to spread out the weight of the structure across a larger
footprint than the foundation would if it was in direct contact with the earth. A footer, because it’s
wider than the foundation wall, displaces this weight over a much larger area. A footer also
creates a nice, level surface for our crew to set our forms.
Trenched foundation
A Trenched foundation is a single layer of concrete, several inches thick. The slab is poured
thicker at the edges, to form an integral footing; reinforcing rods/rebar strengthen the thickened
edge. The slab normally rests on a bed of crushed gravel to improve drainage. Casting a wire
mesh or fiber mesh in the concrete reduces the chance of cracking.
