The Closing of Snell Hall

Wondered why the wood and tin covers were built at the entrances of Snell Hall? They were created as a safety measure because the brick surface is spalling.

Spalling is the deterioration of bricks by crumbling or flaking. The main cause of spalling is water. Brick spall when they are too soft and porous. This permits the brick to absorb and retain too much water which then can freeze and expand breaking away the brick surface.

The entrance covers were constructed to keep the parts of bricks that are fall off the building from hitting people entering the building.
