Follow the construction of one of our homes from beginning
to end. Its a great way to learn more about home construction
and, more importantly, why Prescott Home's standards are second
to none.
After obtaining all necessary permits, surveys
and plans, our first step is to determine how deep to dig
the basement.
Prescott Homes Difference: If you choose the
basement option, your home will have 9 foot basement walls
which allows for a greater ceiling if you finish your basement.
Our basement will also have natural daylight. We first must
determine where the windows will be located in the basement
and be sure that there is adequate yard drainage away from
the foundation. Almost all basement leaks are a result of
poor drainage away from the foundation. Thats why establishing
the foundation elevation is so critical.
As the excavation continues, the grade at the
bottom of the basement is constantly checked with a laser
instrument to insure a level dig.

Digging the basement
The majority of the dirt dug out of a basement
is hauled away to a location pre-arranged with a trucking
company. Some dirt is left on the site to backfill around
the basement.
Once the excavation is complete the concrete
crew moves in to install the footer for the basement walls.
First, a string line is positioned around the perimeter of
the basement walls so forms can be set up for the concrete.
Once all of the forms have been constructed,
a leveling device is used to put the entire footer on a level
grade.
A perforated tile is placed on the interior
and exterior of the footer with short tiles running through
the footer (between wooden forms). This allows any water on
the outside of the wall to travel to the interior tile, then
on to the sump pit where it will be pumped away from the home.
Both the interior tile and exterior tile are covered with
crushed stone. An additional layer of stone will be added
later to the exterior.

Next a Bobcat delivers the basement wall panels
into the basement. The panels are the forms that are used
to pour the basement walls. Notice that the Bobcat runs in
and out of the basement on a ramp of dirt.
Horizontal reinforcement bars are tied to vertical
reinforcement bars using wires and a wire twisting
tool. This wall of steel bars will be inside the basement
walls. They strengthen the concrete, and prevent shrinkage
and cracks from opening wider (Important note: all concrete
will eventually develop cracks which is a normal part of the
curing process!)
Many items are poured into your basement wall.
One such item is a sewer sleeve that will be used to attach
drainage lines from the inside of your home to a single line
that runs to the sanitary sewer.

Wood forms (right) are placed inside the wall
panels (background) to create the void for our basement windows.
When there is limited access to a job site,
a concrete pump is required to transfer the concrete from
the truck to the wall.
After all of the forms are removed, the finishing
touches are completed. A coat of tar is sprayed on the exterior
of the wall, more stone is added on the exterior tile and
stone is placed where any patios or decks will be constructed
to avoid any settling. The tar coating is not to waterproof
the basement it is applied to stop water vapors from
penetrating into the basement.
