How can I lift a sunken paver in the middle of my driveway / patio / walkway / sidewalk?
I've done it two ways. Take a coat hanger and bend a 1&quot; 90 degree at the end of a straightened out hanger. Insert the bent edge down into the seem and twist the hanger so the 1&quot; piece turns under the paver you want to pull up. work it back and forth with a screwdriver in the opposite edge while pulling the paver up.
My other trick was to drill a hole in the paver I wanted to remove and stick in a plastic anchor. Insert the screw, screw it in a bit  and lift up. Save the dust from drilling and when you reset the paver mix it with a little silicone, clear, caulk and stuff it into the hole.
