What each service covers

A short guide to the geotechnical and construction services GarBia Group provides, what each one solves, and where it typically applies. If you are unsure which you need, describe the site and we will advise.

Site Assessment

Desk study and site reconnaissance that establish ground conditions, access, and the scope of investigation a project needs before drilling begins.

Problem it addresses
Committing to a drilling programme before anyone has looked at the ground, access, or nearby structures.
Where it applies
All project types, before an investigation scope is agreed.

Soil Investigation & Sub-Surface Exploration

Standard Penetration Testing (SPT), coring, and test pits to recover samples and record sub-surface profiles for foundation and structural design.

Problem it addresses
Designing a foundation without knowing what the soil below it can actually carry.
Where it applies
Residential and institutional buildings, roads, and government infrastructure.

Geotechnical Testing

In-situ and laboratory testing of recovered soil samples to establish strength, classification, and settlement behaviour.

Problem it addresses
Sample descriptions alone cannot tell you strength, classification, or how much a layer will settle under load.
Where it applies
Any project where foundation loads must be justified numerically.

Detailed Geotechnical Reports

Laboratory analysis, liquefaction analysis, and foundation design recommendations issued as a geotechnical report for the design team.

Problem it addresses
Raw borehole and laboratory data that the structural designer still has to interpret.
Where it applies
Permit submissions and structural design that need a signed geotechnical basis.

Micropiling & Bored Piling Works

Deep foundation works for sites where shallow soils cannot carry the design load, including restricted-access and existing-structure conditions.

Problem it addresses
Shallow soils that cannot carry the design load, or sites too tight for conventional piling rigs.
Where it applies
Soft ground, sloping sites, and works alongside existing structures.

Jet Grouting & Cement Grouting Works

Ground improvement by grout injection to increase bearing capacity, reduce permeability, and stabilise weak or loose ground.

Problem it addresses
Loose or permeable ground that needs improving in place rather than being replaced.
Where it applies
Bearing capacity improvement, seepage control, and stabilising weak ground.

Soil Laboratory Testing

Moisture content, specific gravity, Atterberg limits, grain size distribution, consolidation, field density, maximum dry density, CBR, Los Angeles abrasion, permeability, and unconfined compression testing.

Problem it addresses
Material properties that have to be measured to a recognised standard to be accepted.
Where it applies
Testing follows ASTM standards and specifications in our own laboratory.

How an engagement runs

  1. Tell us the location, structure type, and programme — by email or phone.
  2. We assess the site and agree the investigation scope and number of boreholes or test pits.
  3. Field work: SPT, coring, or test pits, with samples recovered for testing.
  4. Laboratory testing of the recovered samples to ASTM methods.
  5. A detailed geotechnical report, including foundation design recommendations, is issued to your design team.
  6. Where required, we carry out the foundation works themselves — micropiling, bored piling, or grouting.
