THE BASIC PROCEDURE is simple. The bags or tubes are filled with a suitable pre-moistened earth and laid in a mason style running bond. By filling the bags in place on the wall we eliminate ever having to lift them. After a whole row has been laid it is compacted with hand tampers. We then lay 2 strands of 4-point barbed wire in-between every course, which acts as a Velcro mortar cinching the bags in place.
