Services
Three directions, one subject: groundwater. From field investigations and a calibrated model to design documentation, expert review and site supervision.
Design
Working documentation for dewatering, drainage and groundwater protection, with state expert review support and site supervision.
Mine dewatering and depressurisation
Inflow forecasts and drainage schemes for open pits and underground mines, pit slope depressurisation, mine water management.
Details (in Russian) →Drainage systems
Horizontal, vertical, radial and perimeter drains for buildings, industrial sites and territories; pumping stations and outfalls.
Details (in Russian) →Seepage cut-off walls
Slurry walls, secant piles, jet grouting and grout curtains; performance verified on a numerical model.
Details (in Russian) →Reactive barriers
Sorption and permeable reactive barriers that stop contaminant migration in groundwater.
Details (in Russian) →Tailings storage facilities and impoundments
Seepage assessment, groundwater protection and monitoring for tailings dams, sludge ponds and process water reservoirs.
Details (in Russian) →Landfills

Details (in Russian) →Flood and groundwater protection of territories
Protection of land, settlements and industrial sites from flooding and rising groundwater, including the justification of flood-zone boundaries.
Details (in Russian) →Protection of buildings and structures
Diagnosis of waterlogged basements and foundations, drainage and waterproofing solutions verified by modeling.
Details (in Russian) →Geological risk assessment
Probability and damage assessment for flooding, suffosion and landslides; risk management recommendations before construction.
Details (in Russian) →Stormwater and surface runoff
Runoff calculations, drainage networks, retention and treatment of surface water for industrial and urban areas.
Details (in Russian) →Remediation of legacy contaminated sites

Modeling
Numerical models calibrated against field data. The model is the calculation core of every large project we deliver.
Groundwater flow and contaminant transport
MODFLOW and FEFLOW models of inflows, drawdown, barrier performance and contaminant plumes, with forecasts for decades ahead.
Details (in Russian) →Surface runoff and flood modeling
HEC-RAS rain-on-grid models of catchments and floodplains; flood maps and the sizing of protection measures.
Details (in Russian) →Ground thermal regime
Freezing and thawing forecasts for permafrost foundations, thermal stabilisation and seasonal effects.

Consulting
Field data and expert support for owners, designers and mining companies.
Hydrogeological investigations
Pumping tests, packer tests, tracer tests and monitoring wells that measure aquifer parameters directly.
Details (in Russian) →Groundwater monitoring
Monitoring networks and programmes with response criteria for mines, tailings facilities and industrial sites.
Details (in Russian) →Research and development
Applied studies of seepage, contaminant transport and dewatering methods for non-standard conditions.
Details (in Russian) → How we work
From a water problem to a reliable solution
01
Task analysis
We study the site investigation data, the structure and the construction schedule and say plainly which data are missing.
02
Calculation and model
Analytical seepage calculations and a numerical model, a double justification of every decision.
03
Design
A full documentation package - explanatory note, drawings, bill of quantities, specifications, cost estimate. Support during expert review.
04
Implementation
Site supervision, monitoring and adjustment of decisions to the actual conditions on site.
