We offer to analyze the behavior of earth materials. Our geologists and engineers examine the soil and rock layers that make up the earth to determine their physical and chemical properties. Using this information, GEOENGINEERS designs foundations and earthworks structures for buildings, roads, dams, embankments, cuts, foundations, retaining walls, anchors, tunnels and all other structures directly interacting with the subsoil.
With proper planning, a well-thought-out exploration program for subsurface characterization can reduce or even eliminate expensive surprises during and after construction. GEOENGINEERS highly regarded expertise in the geotechnical ground investigation is built upon knowing what questions to ask as well as where and how to gather pertinent information. Our extensive fleet of drilling and support equipment enables us to provide a comprehensive range of field services which include:
SOIL INVESTIGATION
GEOENGINEERS has been in the exploration business since 1997. Specialized in-situ testing methods include Cone Penetration Testing (CPT), Dynamic Penetration Test (DPT), pressure meter testing and packer testing.
We provide services to obtain the following information on soil and rock.
Foundation type and depth
Allowable bearing capacity for foundations
Allowable passive resistance for foundations
Estimated building settlement
Retaining wall design value
Recommendations for site grading and fill compaction
Groundwater and seepage recommendations
Excavation shoring design values
Pavement design values
CORE DRILLING
Our exploration equipment includes drills, cone penetration testing, and our intrusive methods of exploration and sampling, including hollow hand auger, mud and air rotary, rock coring, and direct push techniques. We offer a variety of ranges of coring, GEOENGINEERS correlates the drilling work with help of its expert team of geologists to fulfill the needs of clients regarding the bearing capacity and strength of rock to establish a comprehensive datum for structure and petrophysical and petrochemical analysis of Lime query, coal query. GEOENGINEERS is engaged with all core barrel sizes, shoes and tubes to achieve client satisfaction.
COLLECTION OF SOIL AND WATER SAMPLES
GEOENGINEERS offers the collection of every type of soil and water sample of borehole and their preservation.
Coring by single/ double/triple tube core bailers in rock
Collection of disturbed or undisturbed sample
Collection of water sample
Preserved the samples properly for Laboratory test
Collection of samples for Environmental Assessments & Environmental Impact Statements
PERMEABILITY TEST
Measure the rate of the flow of water through soil
Perimeter drains around a building and infiltration through a dam or landfill structure
Determine permeability, including constant-head and falling-head types
Determine the ability of rock or soil to control water during construction
STANDARD PENETRATION TEST & CONE PENETRATION TEST
GEOENGINEERS help to identify the bearing capacity of soil and rock.
The standard penetration test (SPT) or Cone penetration test (CPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil
Evolution of SPT/CPT
Influence of ground conditions on penetration resistance
SPT/CPT energy measurement
Use of SPT results
Profiling
Soil classification
Determination of geotechnical parameters

Diameters of bored piles range from 0.6 meters to 2.0 m meters
GEOENGINEERS is able to construct pile with percussion, reverse rotary & straight rotary
PLATE LOAD TEST
Plate Load Test is a field test
Determine the ultimate bearing capacity of soil
Determine the maximum settlement under a given load
Provides data for use in the evaluation and design of rigid and flexible-type airport and highway pavements
PILE CAPPING
A reinforced concrete slab is cast over the tops of the pile or group of piles to form a single structural element
INSTALLATION OF PIEZOMETER
GEOENGINEERS Provides and installs every type of piezometer in dams, barrages, tunnels, railway tracks and foundations etc. Piezometers measure pore-water pressure and groundwater levels, providing information essential to:
