Is poured concrete 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.
