Project landscape Fence Building Company Calgary ensures all are fences are built to last. All our post holes are at a depth of 3.5 to 4 feet deep, we don’t dry pack our concrete, we pour and mix our concrete so we get the right consistency every time, we choose the best materials which means no splits down the center of the posts, We use screws on the entire fence not nails or staples to make sure it’s a long lasting finish.
