Why are my bricks crumbling?

Spalling happens when moisture inside the brick expands and contracts due to temperature changes. It causes brick to lose its topmost layer. Because of this, stress builds up inside the brick because the mortar doesn’t let the moisture escape to the surface of the brick where it can evaporate.

Can bricks rot?

Structural Problems With unwanted moisture intrusion, masonry units and mortar can crack. When water enters brick, concrete, or natural stone, thermal expansion can cause the surface to peel, pop out, or flake off. Excessive moisture also results in wall rot, an extremely unsightly and unhealthy condition.

What is a spalled brick?

Spalling is when brick masonry begins to deteriorate to the point chunks of brick are falling from the structure. Spalling starts off as small cracks that grow into bigger cracks until the entire surface deteriorates.

Why do bricks Spall?

Most spalling is caused by moisture from rain, melting snow, or damp soil penetrating the surface of your bricks. The moisture gets trapped inside, then as a result of dropping temperatures, the water freezes and expands. Second, brick that is reclaimed or when used brick is re-layed it can lead to brick spalling.

How do you secure bricks together?

Mortar. Mortar is a spreadable mixture of water, sand, lime and cement used to permanently bond bricks together to create a strong foundation. When mortar dries, it is similar to brick in strength and structure and can withstand precipitation, sunlight, high temperatures and heat, including fireplace flames.

Are brick foundations bad?

Brick foundations are especially susceptible to these problems because pressure will hit the mortar areas hard, causing small cracks to form. From there, the walls of your foundation can actually rotate, so even brick, which is a strong material, can not withstand the sheer force and pressure.
