Expansion will occur when moisture and ferrous metals react through rusting. Do the 29's of these years have a cast iron core? If so, the moisture will cause the iron to corrode and be very serious. An example of this is when concrete reinforced slabs develop cracks sufficient to allow water to penetrate to the rebar. Over time, the slab will fail as an integral unit.
