2. demands of today's market.
GEOPLANO SONDAGENS, LDA.
The GEOPLANO is an Angolan company, founded on 23 February 2006. Its focus is
mainly facing the area of foundations and geotechnical studies and a wide area of
services including geology consulting, project execution and inspection.
Currently the market competition requires the continuous search for innovative and
technically superior solutions in order to enable all Client projects.
Based on the importance of our role in the implementation of Client projects, we have a
technical staff highly qualified distinguished by competence, professionalism and
dedication, with a modern, dynamic and competitive vision.
We are at the source of your projects and our intervention starts in the soil survey and
design solutions in the field of geotechnics which rely on accuracy, promptitude and
competitiveness.
In order to carry out their projects we have a set of equipment able to meet the demands
of today's market.
3. WORK AREAS
The activities we develop, from the design phase are:
GEOTECHNICAL AND GEOLOGICAL INVESTIGATION
SOIL SURVEY: LOGS AND TEST PITS
SOIL AND ROCK MECHANICS LAB ANALYSIS
IN SITU TESTS: SPT, PDL, DPSH, CPT
GEOLOGICAL AND GEOTECHNICAL CONSULTING
HYDROGEOLOGICAL STUDIES
GEOLOGICAL MAPPING
LANDSLIDES SUSCEPTIBILITY ASSESSMENTS
GIS ANALYSIS AND SOLUTIONS
ENVIRONMENTAL IMPACT ASSESSMENT
INSTRUMENTATION AND MONITORING
The technical staff of GEOPLANO has extensive experience in above mentioned
activities, both at project level and at the level of implementation.
4. GEOTECHNICAL INVESTIGATION
Regarding to geotechnical studies GEOPLANO perform the work with two types of drilling
equipment:
PERCUSSION DRILLING
The percussion drilling is a geotechnical geological research
method that performs manual auger probes holes in soils with SPT
tests. The STP tests can recover soil samples (disturbed) and it is
possible to describe the soil profile and correlate the NSPT values
with strength and deformity parameters.
ROTARY DRILLING
The rotary drilling is a geotechnical research method is the use of
mechanized equipment in order to obtain soil and samples
(undisturbed), continuous and cylindrical material. In this type of
drilling method it also can be executed STP tests.
Along with geotechnical drilling methods GEOPLANO provides several in situ tests and
other soil survey methods like test pits, soil profiling, soil mechanical analysis.
