Hi guys. I'm looking for a bit of advice on my next small project.
I am going to put a gate across my driveway and am planning on building the columns using 2 cement blocks side by side alternating direction with each course and then rendering. I plan on anchoring the blocks to the driveway using rebar through the entire column and filling the columns with concrete. I do have a few questions though.
The first is... could I get away with simply dry stacking the blocks? They are going to be filled with reinforced concrete and I can't imaging the mortar would add much strength.
The second question is a method I've come across called dry stacking with surface bonding cement. Basically, you dry stack and simply render with a cement + shredded fiberglass mixture. It is supposedly as strong as mortared construction. Does anyone have any experience with this?
Cheers.
