Landslide remediation
Landslides are geodynamic processes involving the movement of soil or rock masses down a slope due to overloading, reduced shear strength, or external factors such as rainfall, earthquakes, terrain modifications, or erosion. Landslides can endanger infrastructure, buildings, transportation routes, and human lives, and they represent one of the most complex challenges in engineering geology and geotechnics.
The purpose of landslide remediation is to stabilize the slope, prevent further movement, and protect people and property. Effective remediation requires an integrated approach that combines geological, hydrological, geotechnical, and construction considerations, as well as a precise understanding of the displacement mechanisms involved.
Types of landslide remediation measures
a) Structural measures
Retaining walls (reinforced concrete, stone masonry, gabions)
Pile walls and anchored structures
Shotcrete, mesh systems, protective fences
Soil reinforcement (geotextiles, geogrids)
b) Drainage measures
Surface drainage (ditches, swales, gutters)
Deep drainage (drainage boreholes, pipes, geocomposites)
Lowering of groundwater levels using wells or drainage layers
c) Terrain reshaping
Slope regrading (slope flattening, terracing)
Removal of unstable material, sometimes combined with backfilling and compaction
d) Biotechnical measures
Vegetation with deep-rooted plants to reduce surface erosion
Use of coconut mats, turf reinforcements, etc.
Advantages and limitations of different approaches
Various approaches are used in landslide remediation, each with specific benefits and limitations.
Structural measures such as retaining walls, anchored systems, or pile foundations provide high load-bearing capacity, direct stabilization, and long-term solutions. However, they are typically associated with high costs, require heavy construction machinery, and may affect the landscape’s visual character.
Drainage measures are often a critical component of remediation as they reduce pore water pressures and thereby increase slope stability. Their main drawbacks include the need for precise design, regular maintenance, and susceptibility to clogging, which can compromise long-term effectiveness.
Terrain reshaping, such as reducing slope inclination or terracing, is a simpler and more cost-effective solution, particularly for smaller interventions. However, it requires adequate space and is therefore less suitable in urban areas with spatial constraints.
Biotechnical measures, such as planting vegetation and installing erosion control systems (e.g., coconut fiber nets, grass mats), offer an environmentally friendly and low-cost option. Their effectiveness is long-term and depends on successful plant growth and weather conditions, so they are often used as a complement to more technical solutions.
Landslide remediation is a technically demanding and critical task that requires an interdisciplinary approach and in-depth understanding of local conditions. With proper planning, implementation, and maintenance, it is possible to effectively protect people, infrastructure, and the environment from the impacts of slope instability. High-quality preliminary investigations and long-term monitoring of implemented measures are essential for success.
Our services in the field of landslide remediation:
We conduct field investigations, borehole drilling, laboratory analyses, and monitoring to determine the slip surface depth, soil composition, and landslide mechanisms.
We use advanced software tools (e.g., GEO5, Plaxis) to calculate safety factors and design appropriate remediation measures.
We develop technical solutions that include drainage, retaining structures, slope reshaping, and biotechnical measures.
We prepare detailed design (PZI), bills of quantities, cost estimates, and all necessary documentation for building permits and execution.
We install inclinometers, piezometers, and geodetic reference points to monitor displacements, pore pressures, and the effectiveness of implemented measures.
We provide geotechnical supervision throughout the implementation of remediation measures to ensure compliance with designs and execution quality.
We assist with the selection of remediation strategies, phasing of interventions, preparation of tender documentation, and provide technical support throughout the project lifecycle.

Jetmir Rakovec
Feedback from a construction company: “Working with your company left us with only positive impressions! The geological investigations for our project were carried out professionally and in the shortest possible time. All recommendations were clear and precise, which allowed us to avoid unnecessary costs during the construction phase. Special thanks for the detailed reports and your attentive approach to our requirements!”

We required a geological report for the design of a residential house. The Geoinženiring team responded promptly, carried out the drilling and investigations smoothly, and without complications. Communication with the geologist was clear, professional, and timely. We are very satisfied with their approach.

I commissioned a geological survey for a house construction site and was very satisfied! The experts explained all the results in detail and provided clear recommendations regarding foundation selection. I was impressed by their high level of professionalism and friendly attitude. I highly recommend this company to anyone seeking reliable geological services!
