Recently bought an established house (only 4 years old). The previous owners didn't do anything with the backyard so when we were making plans we discovered that there is a gap between the back fence and soil level. The first 2 photos are of the gap. The last photo is what it looks like on the other side.
Basically, not sure how to fill the gap without it costing a fortune and not rusting the fence. Hubby suggested pine sleepers but there would be a slight gap between the fence and the sleepers due to the fence posts. I was told this could be a vermon trap.
The gap is 40cm deep at the deepest point and this spans across an 18m long fence.
Hoping you can help.
Thank you 🙏
