## Geological & Regional Soil Expertise (Parkes NSW)
1. **Red Brown Earths & Calcareous Clays**:
   - Predominant in Parkes, Forbes, and Trundle. Highly reactive with seasonal swelling and shrinking.
   - Solution: Outback Landscaping incorporates lime/gypsum soil stabilization, aggregate sub-base, and geotextile separation membranes under all rural driveways and structural slabs to prevent rutting and subsidence.
2. **Dispersive Sodic Clays (Tunnel Erosion Risk)**:
   - High risk during heavy Central West rain events.
   - Solution: Proper catchment contours, diversion bunds, compacted clay cores for farm dams, and rip-rap rock protection on dam spillways.
3. **Black Soil River Flats (Lachlan Valley / Forbes border)**:
   - Exceptionally deep and plastic when wet.
   - Solution: Heavy-duty geogrid reinforcement (Tensar TriAx) and deep-drainage swales.
