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. You can’t see this crack because it’s often very small, but it exists.
What type of cement is waterproof?
