They differ in the size of gravel used and that concrete blocks are hollow while poured concrete is solid.
Poured concrete basement walls vs block.
Also poured walls have a compressive and flexural strength several times that of concrete block.
Reinforcing steel needs to be in block walls both vertical and horizontal.
Poured concrete is a huge time saver.
A poured concrete wall takes less time to install has more mass is joint free typically is between 6 and 10 inches thick and with the steel rebar that is placed inside the wall it assures you of a less problematic way of constructing a basement wall.
Block is more labor intensive especially as the height of the wall increases.
Poured concrete foundation walls are arguably stronger than cinder block foundation walls.

Without joints poured walls possess a greater lateral strength which essentially means they have a greater ability to resist pressure presented by water and the soil from the outside.
Poured or cast walls must have horizontal steel top and bottom.
It would take a small army of masons to achieve the same results building with concrete block.
Be sure you use lots of steel no matter which material you.
Poured concrete vs block wall tips just below.
Fast tips for poured vs block walls.
So the question becomes does it make more sense to use a concrete poured foundation wall or should you use block.
A poured wall doesn t have joints like a cinder block wall so it should come as no surprise that it is naturally easier to waterproof.
For a poured wall extra height just means taller forms and more materials.
So you re building a basement.
For purposes of the study a 24 by 40 foot basement complete with footings waterproofing and including all material and labor was examined from the standpoint of poured concrete full 8 inch block and modular 7 5 8 inch high block for both frame and veneered homes.
Reinforcing steel can be used to strengthen either material.
Poured concrete foundations provide a high level of strength and durability and can last for decades.
According to the national association of home builders conventional 8 inch concrete cinder blocks cost around 1 46 per square foot of foundation before installation.
Advantages of poured concrete foundation.
Block walls can be as strong or stronger than poured walls.
Block and concrete are strong in compression but weak in tension.
When you re building a new home you want the highest quality for the best possible price.
Block cores must be filled with pea gravel concrete.
Well in our opinion and now with time tested results we have experienced less problems with poured walls than block.
A concrete block foundation can be stronger than a poured concrete foundation.
Poured concrete foundations are fire resistant.
Also the porosity of cmus makes waterproofing more difficult in a full foundation.
