A creek next to our property is eating away the embankment and an engineer suggested using the sand in the creek bed.. wrapping it up in geotextile fabric in the form of a burrito but he did mnot mention how to fasten them shut..any ideas or experience with erosion control out there?
Get some tie wire or baling wire. It's a soft wire used for tying reinforcing steel together or for baling straw. You could also use plastic cable ties.
