Injections in geoengineering

Advanced Soil Stabilization, Waterproofing & Structural Reinforcement

At European Tech Co, we deliver specialist injection solutions for geotechnical and underground engineering challenges. From soil stabilization and void filling to sealing, underpinning, and structural reinforcement, our injection technologies provide a non-invasive, reliable, and cost-efficient alternative to traditional ground improvement methods.

Whether you're dealing with unstable soils, groundwater ingress, underground voids, or aging infrastructure — our injection services are tailored to solve problems at the source, ensuring long-term stability, waterproofing, and load-bearing performance.

🧱 Key Applications:

Strengthening loose or unstable soils
Underpinning existing foundations and excavation pits
Injection piles for additional support
Rock and slope stabilization
Crack and joint injection in concrete and stone
Masonry injection for heritage structures
Filling underground voids and annular spaces
Sealing tunnel rings, steel sheet piles, diaphragm walls
Lifting and stabilizing concrete road slabs
Protection of buildings against settlement
Creating cut-off walls and anti-filtration barriers in sandy or water-bearing soils
Ground remediation in contaminated industrial areas
Stabilizing slabs and floors in residential, commercial, and industrial buildings

🛠️ Materials We Use:

We select injection materials based on the specific conditions of each project, including:

Fine cement slurries and grouts
Polyurethane resins (for fast expansion and sealing)
Acrylic and silica gels
Foamed concrete
Bentonite-based compounds
Specialized soil-consolidating mixtures

⚙️ Injection Technologies:

Low-pressure and high-pressure injection
Jet grouting (in limited cases)
Contact injection (between foundation and surrounding soil)
Structural and void injection
Compaction grouting for soil densification
Anti-filtration injection to form waterproof barriers
Compatible with Long Distance Pumping (LDP) systems — up to 5 km away from the injection point

📌 Where We Work:

Road and rail infrastructure
Hydropower and flood protection structures
Water and wastewater treatment facilities
Microtunneling and deep excavation projects
Foundation slabs, pile walls, diaphragm walls
Residential, industrial, and public buildings
Contaminated or chemically aggressive sites

✅ Benefits of Our Injection Services

Eliminates risks of structural failure or land subsidence
Restores stability and integrity of buildings and underground structures
Adapts to both dry and wet conditions (including water-bearing soils)
Quick curing times for fast operational turnaround
Excellent sealing against water, gas, and chemical intrusion
Non-disruptive to surrounding structures and operations
Ideal for hard-to-access locations where machinery cannot be used
Enables deep foundation support and slope reinforcement
Reduces the need for open excavation or replacement
