The foundation is arguably the most important aspect of your home’s structure.
It must support the structure and transfer its weight to the underlying soil.
The foundation also protects the structure from insects and moisture.
The first step in building a good foundation is installing the footing. The
footing distributes the structure’s weight evenly to the soil below. At Jim
Beard Homes, we excavate a trench 24 inches wide and 12 inches deep to
undisturbed soil. Any stump holes or other soft spots are prepared and
compacted. Two rows of re-bar (steel rods) are then installed in the trench.
The re-bar is bent around corners and to follow the grade elevation. The trench
is then filled and leveled with 3000 psi concrete. The re-bar is placed on
metal supports to position it in the middle of the concrete, thus adding
strength to the entire footing system.
Other builders may state that they also use rebar. Those that do often use it
only horizontally, and not bent around the corners and through grade steps. We
take the extra step in order to give the footing maximum, equal strength.
We then construct a continuous outer foundation wall. If we are building a
single story structure, we use 8"x8"x16" continuous concrete block on the
exterior walls and doubled 8"x 8"x16" (16"x16" solid) interior piers.
In most cases we construct our basements using poured concrete walls. This is
accomplished by erecting forms, installing re-bar both laterally and
horizontally within the forms and connecting the entire concrete wall to the
footing. The form is then filled with concrete and allowed to cure. The forms
are removed after a couple of days. Poured concrete walls provide superior
strength and water resistance.
Other builders may try to talk you into concrete block foundations with water
proof paint. This method is just asking for trouble down the road. Water is the
single greatest threat to foundations. It is imperative to resolve moisture
problems during construction, as shortcuts on moisture control will plague a
homeowner for years.
The first step in moisture control is to properly establish the grade at the
base of the foundation. It must slope gently away from the structure. Gutters
must be diverted several yards away from the structure. We allow for french
drains on most of the homes we build and waterproof all of our basements using
a rubberized membrane and patented drain board. The system is wrapped around
the wall and footing. A french drain is then placed at footing level to drain
excess moisture away from the structure.
On a single level home, the ground is leveled and prepared and a vapor barrier
is applied under the structure.
