Geotechnical Investigation

Ground information for better footing and foundation decisions.

Linfinity Engineering helps owners, builders and designers obtain the right ground information before footing, slab, basement or retaining-wall design is finalised.

We clarify whether the project needs site classification, footing exposure, boreholes or deeper geotechnical investigation, then connect the findings to practical foundation and structural decisions.

Service Fit

When geotechnical information matters

Good ground information reduces guessing. It helps confirm soil reactivity, existing footing conditions, fill, slope and foundation risks before structural documentation goes too far.

Site classification

Site classification information for residential footing and slab design, especially new homes, extensions and townhouse projects.

Footing exposure

Expose and review existing footings so renovation, extension, underpinning or repair decisions are based on real conditions.

Basements and retaining walls

Ground-condition review for excavation, basement retaining walls, drainage and nearby structures.

Foundation risk review

Advice for projects affected by reactive clay, fill, slope, movement, cracking or uncertain existing foundations.

Deliverables

Typical geotechnical and foundation support

  • Advice on what ground investigation is appropriate for the project
  • Site classification information for residential footing and slab design
  • Footing exposure review for existing foundations
  • Foundation, basement and retaining-wall advice for structural documentation
  • Clear handover of geotechnical findings into the structural design scope

Melbourne Support

Based in Camberwell, working across Melbourne.

Linfinity Engineering supports homeowners, builders, architects and developers across metropolitan Melbourne and wider Victoria by arrangement.

Process

From ground uncertainty to foundation decisions.

01

Confirm the design risk

We identify whether the project needs site classification, footing exposure, soil information or deeper geotechnical investigation before design proceeds.

02

Arrange the right investigation path

The investigation approach is matched to the site, project stage, existing information and engineering risk.

03

Apply results to the design

The ground information is used to support footing, slab, retaining-wall, basement and foundation decisions.

Common Questions

Questions before you send drawings or site details.

Send the project context

Upload drawings, site photos, surveys, reports or a short note about what you need. Linfinity will review the scope and respond with the right next step.

Do I need a geotechnical report before structural design?

Many residential projects benefit from soil or site classification information before footing and slab design is finalised. Linfinity can advise what level of ground information is appropriate for the scope.

What is footing exposure used for?

Footing exposure helps confirm information about existing foundations, which can be important for renovations, extensions, underpinning questions or existing-structure assessment.

Can ground investigation be coordinated with structural design?

Yes. Linfinity can coordinate the ground information with the structural design path so foundation decisions are based on relevant site conditions.
