This may not be the most exciting post, but the information is important. We’re seeing photos of earthbag projects under construction that show barbed wire not being installed correctly. The best way is to use long pieces of barbed wire, preferably pieces that continue around the entire structure. Overlap the ends of the wire about 2’ and tie securely with two pieces of galvanized wire. Join the ends (overlap) in a long section of wall. Don’t join the ends at corners, because that’s an area often under greater stress. This is especially important in seismic areas. And if you have to use shorter lengths of barbed wire, join them in the same manner (2’ overlaps located away from corners).
