The Challenge

What lies beneath your site?

Ground conditions are rarely uniform. Soil, weathered rock, fractured zones, groundwater, geological structures and buried features can vary significantly across a project site.

GEO GIS SERVICES combines geological observation, direct investigation, geophysical methods and geospatial analysis to develop a clearer understanding of subsurface and terrain conditions.

Before design and construction — understand the ground.

Our Approach

Field data is only useful when it can be understood.

01

Geology

Understand the geological materials, weathering, structures and terrain controlling ground conditions.

02

Investigation

Select appropriate direct and indirect investigation methods based on the project objective.

03

Data

Process and review field measurements with appropriate quality-control procedures.

04

Interpretation

Translate investigation results into maps, profiles, models and technical conclusions.

Our Workflow

From site question to technical understanding.

A consistent investigation workflow so scope, methods and outputs are matched to your project's actual ground-risk question — not a fixed package applied to every site.

01
Understand

Establish the project objective, site setting and specific ground-related question.

02
Assess

Review available geological, terrain and historical information, with site reconnaissance where required.

03
Investigate

Implement appropriate field methods according to the investigation objectives.

04
Process

Check and process field data, ready for interpretation.

05
Integrate

Assess geological observations, investigation results and spatial information together.

06
Report

Present results through appropriate technical figures, maps, profiles and written interpretation.

FAQ

Common questions.

Can geophysics replace boreholes?
Not automatically. Geophysical methods provide indirect information about the subsurface, while boreholes give direct observation at specific points. Depending on the project, the two approaches can complement one another rather than substitute for each other.
What can ERT (resistivity) investigate?
ERT measures variation in subsurface electrical resistivity. Depending on geological conditions, survey design and data quality, resistivity contrasts may help identify changes associated with soil, weathered rock, groundwater, fractured zones or bedrock. Interpretation is always considered alongside geological context and any available verification data.
What is a Parallel Seismic Test used for?
It estimates the depth of an existing foundation or pile where no design records are available — useful for older structures being assessed, extended or rehabilitated.
What information do you need to prepare a proposal?
Useful information includes the project location or coordinates, the project type, the ground condition you need to understand, and any site plan or previous investigation report you already have. Share these through the proposal form or WhatsApp.
Which areas do you cover?
GEO GIS SERVICES is based in Kajang, Selangor, primarily serving the Klang Valley, with field experience extending to Putrajaya, Terengganu and other parts of Peninsular Malaysia depending on project requirements.
