Hey everyone. So I live in an area that is mostly clay underneath the ground. To keep my foundation from shifting when it contracts during the dry months, I have to water it regularly. I have a soaker hose that runs around the house, placed 1 foot away from the foundation.

This creates a problem with mowing where I can't just let my robot mower (or my push mower) run freely because of the risk of the soaker hose getting caught up in the blades, which has already happened once when I accidentally mowed too close.

To resolve this, I want to kill the grass (using landscaping fabric) in the 1 foot space between the foundation and hose and replace it with something else so I don't need to bother manually trimming it. At the same time, I don't want to use organic stuff like mulch because underground termites also exist in my area and I don't want it to attract them close to the foundation.

A brief search pointed me to using gravel. However, the problem with stones (especially larger ones) is that they also trap moisture underneath them, and the dark and damp areas can also maybe attract termites. Reading a bit more, I think a good compromise would be smaller and uneven gravel/rocks, as more space between them means sunlight penetrates more and moisture gets dried up quickly. Is this a good solution?
