Hydrogeology (groundwater analysis)

Hydrogeological surveys constitute an essential branch of geotechnical engineering investigations, dedicated to comprehensive exploration of groundwater aquifers, water table fluctuations, filtration dynamics, and subsurface chemical interactions.

Groundwater drives half of all foundation decisions: depth, waterproofing, and the need for drainage and dewatering. Hydrogeological investigation establishes water levels and their seasonal variation, chemical composition and aggressiveness to structures, and forecasts flooding of the area.

Across Tashkent and all developing regions of Uzbekistan, the accredited engineering center GEO PRO provides certified hydrogeological surveys Tashkent with full guarantees for state departmental expertise approval.

A timely and highly accurate groundwater analysis for construction empowers structural engineers to select the most cost-effective foundation systems, preventing severe flooding risks in basements and underground parking facilities.

Conducting a thorough groundwater level assessment Uzbekistan prevents uneven soil subsidence, concrete degradation, and loss of structural bearing capacity during seasonal high-water periods.

Why Hydrogeological Surveys are Essential for Construction Projects

In accordance with the Urban Planning Code and statutory building regulations of the Republic of Uzbekistan (KMK / ShNK standards), hydrogeological surveys are mandatory for:

• Designing deep foundations and multi-level underground parking for high-rise developments;
• Constructing industrial facilities, water treatment reservoirs, and critical subterranean utilities;
• Evaluating the hydrogeological impact of deep excavation pits on neighboring existing urban structures;
• Designing temporary construction dewatering and surface water interception systems during earthworks;
• Justifying long-term anti-seepage protection, drainage layers, and flood mitigation measures;
• Underpinning, reinforcing, and reconstructing existing building foundations affected by rising groundwater tables.

What We Do: Field Testing and Hydrogeological Exploration

The specialized hydrogeology department at GEO PRO conducts the complete spectrum of field measurements and in-situ hydraulic tests:

• measuring groundwater levels in boreholes and seasonal variation;
• water sampling and chemical composition analysis;
• assessing water aggressiveness to concrete and steel;
• pumping/filtration tests and flooding forecast;
• performing single-well and cluster pumping tests to determine aquifer hydraulic conductivity;
• calculating permeability, transmissivity, piezometric heads, and specific yield coefficients;
• installing dedicated piezometric monitoring wells for long-term hydrodynamic regime tracking.

Laboratory Assays and Water Aggressiveness to Concrete Testing

In our ISO-certified analytical laboratory, engineers conduct specialized water aggressiveness to concrete testing, evaluating corrosion risks for rebar reinforcement and protective coatings.

Chemical assays identify concentrations of sulfates, chlorides, bicarbonates, magnesium, calcium ions, free carbon dioxide, pH levels, and total dissolved solids (TDS).

Based on laboratory test protocols, structural designers select the required concrete impermeability grade (W), sulfate-resistant cement types, and appropriate primary/secondary waterproofing barriers.

Aquifer Hydrodynamic Modeling and Dewatering Calculations

Modern hydrogeological surveys require analytical and numerical modeling of subsurface water flow patterns.

GEO PRO engineers compute expected seepage flow rates into construction pits, calculate the radius of influence of depression cones, and size the required wellpoint dewatering installations.

This precise mathematical modeling prevents mechanical suffosion (piping) of fine sand particles from beneath adjacent operational buildings.
