In this video tutorial, viewers learn how to add strength to a landscape patio wall. For reinforcement, users should insert metal pipes down through the wall. To do this, users will need a sledgehammer, 1/3" pipe and a large diameter pipe cutter. Determine the length of the pipe by adding 2 feet to the actual length of the wall. Cut the pipe to the length and insert the pipe down through a large diameter hole on the wall. Remove the surrounding blocks and use the sledgehammer to drive the pipe down. Now place back the top blocks. Finish the wall by adding wall caps. This video will benefit those viewers who have a patio wall and would like to learn how to make the wall stronger in case of a storm or an accident that could destroy the wall.
