Hi Everyone, I would like to ask your expert advice in how to build a fence on a bank (steep slope 1-3 m high). Please see photos. Background: The house is next to an open field. The field is on a higher ground which was filled with land. This ground is higher than the house. https://photos.app.goo.gl/wQkytm1Yc9QeK56Y7 Option 1: Building a concrete wall 3 sides after clearing the whole area As the boundary of the fence is on a high and lower ground, should we dig down to flatten and clear the ground for the fence? If we clear the soil and build a concrete wall, 3 sides, we don't know over the time if the ground on the high level will push the concrete wall + the fence (one side) when the ground is wet. (In the past, we have a garden like this . Over the time, we started to see crack on the wall, as the force on the high ground started to push against the wall) Option 2 : Build a trench for 2 gravel boards stacking up If we only dig down to create a trench for putting down two gravel boards stacking up on each other. Without flatten and clear the ground too much, the bank or the slope is still remained and the soil will act as a barrier. Is this option better than option 1? The builder told us that the 2 gravel boards stacking up will not be even when we build a trench. The barrier will not be deep enough to hold the force and will be pushed away. Building a concrete wall is an expensive option but better. So the main questions are 1) Should we clear the area on a bank before installing a fence ? We can clear the area, but then we will have to reinforce the lower ground with something else as the ground level is divided even more and we will have to maintain this barrier. 2) Can we use the gravel boards instead of building a concrete wall ? Many thanks for your advice.
