Poured concrete wall average cost.
How thick should a poured concrete wall be.
The projection of the footing on either side of the wall is supposed to be no greater than the depth of the footing.
The thickness of concrete is an important factor in load bearing strength but to conserve resources and avoid over building other factors are also taken into consideration.
In order for a concrete room to effectively resist high winds and flying debris most rooms built with precast concrete walls rely on 12 to 16 inch thick blocks.
Table 4a is based directly on the aci method but for table 4b the author has applied a reduced strength reduction factor a factor of safety.
So for example a 32 inch wide footing under an 8 inch wall would need to be at least 12 inches thick.
The one force is a downward force gravity load created by the load placed upon the wall.
However let s compare two 8 inch thick walls.
In general poured concrete basement walls that are 8 feet tall or less and have no more than 7 feet of soil pressing against them from the outside function well at a thickness of 8 inches.
When a taller wall or a higher level of soil or both come into play the thickness should increase to 10 inches.
This can add several inches to the wall s thickness dimensions and can vary depending on the severity of exposure soil type and reactivity etc.
That s because a footing that s too wide and not thick enough will experience a bending force that could crack the concrete.
For plain concrete walls which are walls without or with little reinforcement 7 1 2 inch thickness is adequate.
Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well.
Structural concrete work is planned to bear loads or hold weight but transfer the weight to the soil base beneath the structure.
Increasing the strength of the concrete mix or the thickness of the wall increases the wall s capacity.
So taller walls in heavier soils should be made thicker or with stronger concrete.
There are two forces which act primarily upon foundation walls.
As a material concrete is usually divided into concrete blocks and poured concrete walls.
The minimum thickness is also determined by wall height soil classification and the height of unbalanced backfill or backfill on only one side of the wall.
Several factors determine the cost of a poured concrete wall such as the dimensions of the wall the thickness its height and its length the number of reinforcements present and the quality and type of concrete used.
The other force is a sideways or lateral force.
How thick should a concrete retaining wall be.
To keep the house and the room from being sucked into the air during a tornado large footings that work like anchors are added to the walls to hold the room in place.
