I'm working on plans to put a "skirt" around the slab of the house both for weed control/ termite visual inspection and to stop any water pooling against the slab.

I've settled on crushed concrete aggregate.

My thoughts, which I'd love your feedback on, is to use clay / soil from around the site, tamp it at a slight angle away from the slab, then put something (crusher dust, screenings?) down, geofabric, then aggregate.

Does that sound about right? Am i missing something? Over thinking it? Someone suggested stabilised sand rather than crusher dust / screenings - overkill?

Thoughts most welcome.

Cheers

    It may take a few years, but you'll have weeds. Dust, organic material and weed seeds will collect above the geotextile - and weeds will happen. – Ecnerwal Apr 03 '22 at 11:33
  • I'm curious how this will help with "termite visual inspection". Not doubting you, just not understanding. – FreeMan Apr 03 '22 at 12:04
  • Ercnewal - yeah understand this. inevitable for sure but I feel weeds will be easily removed as they dont have a strong rootbase due to the geofabric. – Geek Apr 03 '22 at 21:59
  • Freeman - the aggregate will have a 100 - 150mm gap to the top of the slab so we'll see any termite tunnels running up to to the timber frames. – Geek Apr 03 '22 at 22:00
  • I've seen weeds on top grow roots right through fabric, but I can't swear it was "proper geofabric" as opposed to "crappy misnamed weed barrier." – Ecnerwal Apr 04 '22 at 23:38
  • yeah agree. Did you put anything like roadbase or screenings down under the geo? – Geek Apr 05 '22 at 05:52
