Good day guys, I'm building a 10-ft high concrete retaining wall 12-in thick with a 10-ft radius curve. Looking for advice on forming. Was figuring on using two pieces of 3/8 inch plywood with 2x4 verticals every 12 in. Does that sound like enough support? On the curve section should I just do...

I am preparing to pour a patio with a 12 inch deep footer around the outside edge. I am using a 2X12 to frame it, but I am trying to determine: 1. How deep do the stakes need to go into the ground 2. Would 2X4 stakes every foot suffice 3. Do I need kickers to make sure the stakes don't move...

We have started to build the form to a 600 SQ FT Patio using 8" wide pieces of Hardi siding. ( much of the patio is curved) I'm starting to wonder now if they will hold up to the weight of the concrete. Any suggestions or advise please.
