Hi all,
I have drainage issues with my lawn. In certain areas of the lawn water pools for 2 - 3 days after medium / heavy rain. I have dug inspection holes (20cm x 20cm x 20cm) across the lawn to understand what may be causing the water to sit at the surface and have come across hard light grey / sandy / rock type soil. If I keep digging away at this soil / rock slowly breaks apart but it is does take a bit of effort (see pictures).
Does anyone know if this is some clay variant or something completely different? Also, any recommendations on how to help with drainage i.e. digging auger holes 1m down and backfilling with gravel and top soil?
The lawn is approx. 40 sqm and is a mix of Kikuyu and Sir Walter Buffalo with approx. 80% of the lawn in shade all day and I'm located in Melbourne.
Thanks!
