See below for more information on contraction joints remove forms and install waterproofing and drainage system.
Increase height of poured concrete walls.
Allow concrete to cure.
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.
Create contraction joints every 4 6 feet.
As soon as you go higher or have greater depths of soil pushing against the wall you need to increase the thickness to 10 inches.
Poured concrete walls cost.
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.
If the full hydrostatic pressure assumption was imposed the lift height would be limited to 11 feet requiring more than three separate concrete placements.
Poured concrete wall average cost.
Pour footings and wall.
A poured concrete wall averages 6 153 for homeowners around the country with most people paying between 2 870 and 10 272 you might pay anywhere from 932 to 25 000 depending on the size materials design and overall labor.
In actual practice each wall was completed in a single continuous pour in one day.
It s my understanding most residential concrete foundation contractors typically only have forms that will pour a max 8 or 9 foot wall height.
In a walkout foundation situation when you have footing steps in order to get to the frost depth what s the typical method to get to a taller overall wall height.
If the wall exceeds four feet in height footings should be poured separately.
