Evening all, Wonder if anyone can help? I'm having a new drive put in with brick pillars for automated gates. I'm just wondering if the proposed pillars will be strong enough. They will be; 2.5 bricks wide and 2.5 bricks long (square shape) 1.8 meter tall plus pier cap Distance between the pillars will be 4 meters. Each gate leaf will be 2.25 meters wide, 1.8 meter high weigh roughly 220kg each. It's been proposed to strengthen the pillars with rebar and then concrete fill. Would this be sufficient? Thank you!
