Playing with Concrete: May 29, 2009: My third attempt at pouring a little quarter pipe. I Used a 94 pound bag of Portland Cement ($9.74) 2 bags of sand mix ($2.50) and 3 bags of the gravel mix ($3.34) that the instructions suggested. Sheet of plywood ($12) 2x4's ($) and some chicken wire to pour the crete on..(don't remember the cost) The pictures below are the result. Go ahead honey dork up the driveway some more! ~ home
