Entire sidewalks can be covered over time.
Ironically, weedeating is the preventive measure that prevents this.

Add enough ash and the PH will be to skewed for anything to grow.
A layer of un-charged charcoal will suck the water and nutrients right out of the soil.
Both if these effects will fade with time, but the materials used can be sourced for free and are natural and be.

Normally adding uncharged charcoal to soil could be a problem because it makes the nutrients unavailable for plants, but for your purposes it's ideal.

She doesn't - at least not in my biological zone. We have an area where a former owner dumped a mix of subsoil mixed with some debris and compacted it with machinery driving over it. Himalayan Blackberry and Burdock moved in as they both will grow and break up compacted soil.
