Are poured concrete walls better than block?
Poured concrete wall foundations are arguably stronger than cinder blocks. Poured walls have a better lateral strength, which means they are able to resist more pressure from the water and the soil from the outside. Poured walls tend to be the preferred choice of new construction builders.
Which is stronger a poured concrete wall or concrete block wall?
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.
Do poured concrete walls leak?
POURED CONCRETE WALLS typically leak along the joint between the floor and the wall. High hydrostatic pressure outside the foundation can cause water to seep through solid concrete walls. CONCRETE BLOCK WALLS will leak along the floor/wall joint, just like poured concrete walls.
How thick should concrete walls be?
As a practical consideration, residential designers need to keep in mind that concrete foundation walls are typically 6, 8 or 10 inches thick (nominal). The typical concrete compressive strength used in residential construction is 2,500 or 3,000 psi, although other strengths are available.
Do poured concrete walls crack?
Are foundation cracks normal? Yes, and they usually are no reason to panic. In fact, most cracks in a poured concrete foundation are a natural result of foundation settlement and shrinkage of the concrete during the curing process and can be easily fixed or simply left alone.
Are cinder block walls filled with concrete?
The concrete blocks that are used to build block foundations are hollow. After the concrete blocks are laid, the voids can be filled with a cement-based mortar or poured concrete that contains small pea gravel. If the builder does this, the filled concrete block walls become nearly identical to poured concrete walls.
Are concrete block walls Hollow?
The residential and commercial construction industries make wide use of a form of concrete building material known officially as a concrete masonry unit (CMU). These hollow-core blocks can be made of standard concrete with traditional sand and gravel aggregate held together with Portland cement.
How much weight can a concrete wall hold?
Non-reinforced concrete or concrete masonry products generally are only 1/10th as strong in tension than in compression. That means that if a concrete wall is rated for 3,500 pounds per square inch in compression, it will only be able to withstand 350 pounds per square inch when subjected to a tension force.
