Wrapping walls in mesh – starting under the first course of bags and going over the top of the bond beam – is a simple way to add a great deal of extra strength to your earthbag structure.
Fishing net and plastic lath are ideal for wet climates. Galvanized wire lath or chicken wire is suitable for most situations.
Overlap mesh at least 12” (30cm) and keep seams at least 24” (60cm) from corners.
Lay 24” (60cm) pieces of strong twine or cord across the bags every three or four courses and every 24” (60cm) horizontally along the wall. Use this to firmly tie mesh on both sides of wall together.
