>I am working on a rehab of a dam with a rubble masonry downstream face
damaged in Hurricane Floyd. According to inspection reports, there has not
been mortar noted in the joints for over 20 years; it was decribed as
"ungouted." I suggested that it might have been dry laid in the first
place,
but one of the engineers insists that it must have had mortar, which has
spalled off because of water penetraton. So we are in the process of
deciding
mortar color, consistency, joint profile etc. But...... could a downstream
masonry face of a dam have been laid up without mortar?

Are you STILL working on that dam' project? Ever find out where the stone
came from?
