Water is one of the most powerful elements impacting any engineering project. Uncontrolled groundwater can destabilize excavations, compromise deep foundations, and flood underground structures. Conversely, locating and managing sustainable groundwater resources is vital for industrial plants, agricultural projects, and clean water supply systems.

Our company provides professional Hydrogeological Investigation Services. By combining advanced subsurface drilling, specialized field testing, and mathematical modeling, we deliver precise data on groundwater behavior, aquifer characteristics, and chemical water quality to safeguard your structures and optimize water resources.

Our Core Hydrogeological Capabilities

We offer full-scale field investigations and engineering analysis to address complex groundwater challenges:

1. Hydrogeological Drilling & Borehole Logging

We deploy specialized drilling rigs to construct deep exploratory boreholes, allowing us to map out the underground water-bearing layers (aquifers) and impermeable strata:

• Continuous logging of soil and rock formations to identify water-bearing zones.

• Measuring static and dynamic water levels across multi-layered aquifer systems.

2. Aquifer Pumping Tests (Pumping & Recovery Tests)

To determine exactly how much water an aquifer can yield and how fast water flows through the ground, our field engineers conduct rigorous pumping campaigns:

• Step-Drawdown Tests: Evaluating the maximum efficiency and optimal pumping rate of a well.

• Constant-Rate Discharge Tests: Pumping water at a fixed rate over an extended period (24 to 72 hours) while monitoring drawdown in observation wells.

• Recovery Tests: Measuring how fast the water level returns to normal after pumping stops to calculate accurate Transmissivity ($T$) and Storativity ($S$) coefficients.

3. Deep Dewatering System Design for Excavations

For deep basements, metro stations, or marine foundation shafts, managing incoming groundwater is critical for safety. We analyze field data to design optimal construction dewatering systems:

• Designing deep well points, vacuum wellpoint systems, or perimeter recharge wells.

• Calculating required pumping capacities and predicting drawdown cones to prevent settlement risks in neighboring structures.

4. Groundwater Quality Analysis & Sampling

We collect contamination-free groundwater samples directly from monitored boreholes for strict laboratory testing:

• Testing for physical and chemical parameters (pH, Total Dissolved Solids, hardness, iron, heavy metals).

• Assessing water aggressiveness against concrete and steel reinforcements to guide foundation material selection.

• Evaluating groundwater suitability for industrial, agricultural, or domestic use.

5. Permeability & Infiltration Testing (Slug / Packer Tests)

We determine the hydraulic conductivity of specific soil and rock layers directly in the field:

• Slug Tests: Rapidly changing the water level in a borehole to evaluate localized permeability.

• Packer Tests: Isolating specific rock fractures or sections using inflatable packers to measure water pressure and seepage rates in bedrock.
