Seal Horizontal Terra Cotta to Prevent Water SeepageSeal horizontal terra cotta to prevent water seepage: Water enters the joints between terra cotta units. Water can only escape by seeping through concrete between bricks. Salt leaches through to stain bricks, steel reenforcement corrodes, pushing bricks out of alignment.
FIX: Put a flexible seal-tape over joints, keeping water out.
