I am extending my walkway, going from the patio to the greenhouses. I am using pavers that weigh 25-35 lbs., depending on size. Before placing the pavers, and then mortaring them in place, I had to dig out the sod and level the area. Now that's what I consider to be a chore. My back seems to be handling all this so far. I just get stiff bending over/squatting so much.
