Geotechnical Solutions. Built on Understanding.
Clear Ground Insight.
Confident Decisions.
GeoReach Consulting provides independent geotechnical and ground engineering advice — helping property owners, designers, and developers understand site conditions early and manage risk throughout a project.
We translate soil, slope, and groundwater information into clear recommendations that support design, consent, and construction. From pre-purchase due diligence to construction sign-off, we help you move forward with confidence.
What We Do
Geotechnical Services Across the Full Project Lifecycle
We support projects across residential, commercial, and small‑to‑medium scale infrastructure developments — from geotechnical investigations and design through to construction support and certification.
Geotechnical Investigations
Before design or development begins, it is important to understand what the ground conditions mean for your site. We assess soil, rock, groundwater, and seismic considerations and explain their implications clearly.
- — Site visits
- — Boreholes and soil testing where required
- — Groundwater assessment and monitoring
- — Assessment of ground conditions and stability
- — Clear, council-ready geotechnical reports
Geotechnical Design & Ground Engineering
Ground conditions play a key role in how structures are designed and built. We provide design services tailored to site conditions, including soil-structure interaction analysis and Producer Statements (PS1) where appropriate.
- — Foundation design input and recommendations
- — Ground improvement design and assessment
- — Retaining wall design and geotechnical support
- — Earthworks and slope stabilisation design
- — Liquefaction assessment and mitigation design
Slope & Land Hazard Assessment
Slope instability is one of the most serious geotechnical risks on sloping or variable terrain. We provide rigorous slope stability assessments and land hazard evaluations with clear, actionable advice.
- — Landslip and slope stability assessments
- — PC120 landslide hazard risk assessments
- — Natural hazard reporting
- — PS1 geotechnical sign-off for slope-related design
Ground Settlement & Movement Assessment
Ground movement and settlement can affect existing buildings or proposed developments. We assess causes and potential impacts, providing clear advice on risk and remediation options.
- — Ground settlement assessments
- — Assessment of movement affecting foundations
- — Identification of likely causes of movement
- — Advice on mitigation or remediation options
Construction Support & Certification
Geotechnical involvement during construction helps confirm works are consistent with design assumptions and consent conditions.
- — Earthworks monitoring, testing and certification
- — Geotechnical Completion Reports (GCR)
- — Foundation and subgrade inspections
- — Producer Statements — Construction Review (PS4)
Property Due-Diligence & Pre-Purchase Advice
Understanding ground-related issues early can prevent unexpected costs or limitations later. We provide concise assessments identifying potential geotechnical constraints.
- — Pre-purchase geotechnical appraisals
- — Desktop and site-based assessments
- — Clear risk summaries for decision-making
Independent Review & Expert Services
We provide independent geotechnical review of reports and designs prepared by others for regulatory compliance, council requirements, or second opinions.
- — Independent peer review of reports and designs
- — Producer Statement — Design Review (PS2)
- — Independent assessment for council purposes
Stormwater & Wastewater Assessments
We assess soil soakage capacity, site constraints, and regulatory requirements to support compliant, site-specific system design and consent applications.
Delivered in partnership with trusted specialist consultants.
- — Stormwater soakage and detention assessments
- — Wastewater disposal evaluations
- — Supporting documentation for consent applications
