Construction & repair of utility networks
We carry out a full range of work on laying and reconstructing water, sewer and gas networks from polymer materials — both with trenchless technologies and the open-cut method.
Horizontal directional drilling (HDD)
Laying external networks under roads, rivers, railways and dense development without opening the surface. Especially effective in built-up areas — fast, with no damage to landscaping.
Guided auger boring
Trenchless jacking of large-diameter pipes and steel casings with a guided pilot bore and auger spoil removal.
Guided piercing
Trenchless installation of pipes and casings up to DN 350 from a compact launch pit without opening roads or landscaped areas.
Open-cut (trench) method
Classic construction and repair of water and sewer networks from polymer materials with trench excavation — where it is reasonable and cost-effective.
Trench and excavation shoring
Installation of temporary steel panel and bracing systems to support excavation walls and provide a safe underground work area.
Pipe relining (rehabilitation)
Restoring old networks from the inside with polymer liners — without full pipe replacement or major earthworks.
Pipe bursting
Pipe bursting — a modern trenchless method of replacing worn utilities: a hydraulic rig bursts the old pipe (steel, cast iron, ceramic) underground and simultaneously pulls a new polyethylene (PE/HDPE) pipe into its place, usually of a larger diameter.
Polyethylene pipe welding
Butt and electrofusion welding of PE pipes of any diameter with weld-quality control. Tight joints for decades.
Video diagnostics & tele-inspection
Inspecting the internal condition of pipelines and collectors with a camera — precise location of defects, blockages and damage.
Hydrodynamic cleaning & milling
High-pressure water cleaning, mechanical and hydrodynamic milling of steel, cast-iron, concrete, asbestos-cement and plastic pipes.
Utility tracing
Pinpointing the exact location of existing underground utilities and producing as-built network schemes.
Construction dewatering
A set of measures to lower the groundwater level for safe work in pits and trenches.
Material selection & supply
We select and supply materials for your project — pipes, fittings, shut-off valves, manholes. Supply as part of turnkey works, matched to the technology and loads.
