House Foundation Term Anchor Bolt is a large metal bolt, which is embedded in the outside
perimeter of most concrete foundations. These bolts come in different diameters. The most
common one used in residential building is 1/2 x 6 inch. Anchor bolts are sometimes referred to as
"J" bolts because of their shape. Once the framing starts, these bolts are used to anchor the
bottom plates to the foundation.
House Foundation Term Slump is a term used for concrete to express how wet or dry the mix. Slump is determined by
pouring concrete in a cone-shaped metal container and letting sit for a specified period of time, then lifting the cone. The
distance in which the concrete drops from the original height once the cone is removed is considered the slump. The
greater the distance, in which the concrete drops, the higher the slump and the wetter the concrete mix.
House Foundation Term Rebar refers to steel rods, which are put in footings and grade beams in a concrete
foundation. These could vary in size depending on the structure and what size foundation is being poured. Rebar
normally used in residential construction is #4 or #5 rods. Rods specified as #4 are ½ " in diameter.
House Foundation Term Brick Ledge is normally depression placed in the outside perimeter of
the house wherever brick will be located. This depression is created by attaching a 2x6 piece of
lumber flat-ways in the side of the foundation exterior vertical form. When the concrete is poured,
it will be screeded off level with the top of the 2x6 and exterior form board. After the concrete has
set up, the forms are removed. This will leave a depression in the slab 5 1/2 " wide and 1 1/2 "
deep.
Foundation





High Early
House Foundation Term High Early is a chemical put in concrete to produce heat and speed up the curing process of
concrete after it is poured
Pea Gravel
House Foundation Term Pea gravel is a small gravel about the size of a pea. It is used sometimes in concrete mix when
the finish is to be exposed.
Form Boards
House Foundation Term Form boards are boards that are used to form up or build the form used to hold in the concrete
until it has set up and become hard. After the concrete has set up, the forms are removed
Foundation Wire
House Foundation Term Foundation wire is used as a re-enforcement for concrete slabs. The wire can be bought in rolls
or matts. The rolls are normally used in residential construction. This foundation wire is also called wire mesh and is placed
and tied across the whole area of the slab foundation after the poly is laid
Edging
House Foundation Term Edging refers to the process of edging the concrete next to the form. This is done with an
edging tool and creates a rounded edge on the outer perimeter of the slab or porch. This will prevent cracking and
chipping on the outer edge when the forms are pulled.
Post Tension Slab
House Foundation Term post tension slab uses sleeved cables instead of the convential rebar and wire mesh. The
cables are placed on chairs in the foundation. These cables are placed in two different directions perpendicular to each
other. This will form a grid with a constant spacing. After the slab is poured and is allowed to cured for a specific time,
tension is applied to the cables , which then becomes the structural support for the slab
Back Fill
House Foundation Term Back fill means the process of back filling against a form, retaining wall, bulkhead etc.. This is
normally done to provide support for the form or retaining wall. Towards the end of a project, the back filling is done to
bring the soil up to final grade
Foundation Embeds
House Foundation Term Foundation embeds are structural pieces which are poured in the concrete when the
foundation is poured. These embeds provide the structural strength to help hold the building on the foundation. There are
many types of embeds. The type and placement is directed by the structural engineer or architect
Stirrups
House Foundation Term Stirrups are rebar pieces that are pre-bent and are used to tie regular rebar to in order to form
a particular shape. In a footing you might have four #5 rebars. These four might be tied to #3 stirrups and for a rectangle.
These are placed and supported in the footings or columns.
Floor Drain
House Foundation Term floor drain is just as it states. Floor drain are commonly used in wet areas or areas have a
possibility of getting wet. These might be installed in laundry rooms or open stair wells. Floor drains are covered with a
metal grate type cover, to allow water drain but prevent any trash from entering the drain.
Soil Moisture
House Foundation Term Soil moisture is stated as a percent based on the sampling. In the process of compaction,
moisture is an important factor in determining the rate of compaction. When a soil sample is taken and tested, the results
will state what optimum percentage of moisture is needed to obtain the required compaction
