Hey i have a few questions, 1. Where did you get the cement all? and 2. On the very first post, last picture you show the 2x4's on their sides, with what appears to be holes drilled in them... Whats the reason for this and 3. does this mix have to be cured in water? And lastly great write up. Ive tried other "mixes" in the past with poor unprofessional results, this looks promising....
