Concrete is not waterproof, but it is so dense that it takes water a long time to get through it.

Does cement hold water?

Yes, concrete can absorb water because it's porous like a sponge. When the ambient relative humidity is high, concrete can absorb water vapor (moisture) from the air.

Is brick and mortar waterproof?

While the brick itself is very resistant to water passing through it, and to a degree the mortar between the brick, the interface where the mortar touches up against the brick provides a pathway for water to enter into a brick wall.

How long does it take for mortar to harden?

Mortar typically will cure to 60% of its final compressive strength within the first 24 hours. It will then take about 28 days to reach its final cure strength. However the curing process does not always follow a universal timeline. There are a few key environmental variables that affect your mortar cure time.

Does water go through mortar?

While the brick itself is very resistant to water passing through it, and to a degree the mortar between the brick, the interface where the mortar touches up against the brick provides a pathway for water to enter into a brick wall.
