Consolidation of the base soils and filling of voids (cavities)

Risk points for the formation of voids and cavities
Sinkholes or voids can appear in many places: residential homes, gardens, highways, and shopping center parking lots. While sinkholes are relatively rare, there are several common natural and human-made causes that can lead to their formation. These causes are often exacerbated by flowing water and the passage of time. Nearby construction or earthworks, leaking pipes, re-cultivated landfills, as well as typical mining or tunneling activities, can also affect the stability or bearing capacity of surrounding soil layers, leading to voids and potential sinkholes.

Watch for these potential warning signs:
  • Cracks forming in the ground outside
  • Unexplained depressions or holes in the ground
  • Trees or fence posts leaning or falling
  • Rapid appearance of a hole in the ground
  • Deformation or tilting of building structures
  • Cracks and damage in building constructions

Comprehensive Restoration Solutions
Uretek technologies represent a set of methods and materials used for various complex geotechnical solutions, including the filling and sealing of large underground voids and sinkholes. This comprehensive solution is exceptionally lightweight while providing excellent load-bearing capacity both within and above the void area.

Groundwater:
When water creates natural underground flows, the soil beneath the surface layer can slowly collapse or be washed away, forming voids. Over time, the underground void grows, causing the surface soil layer to thin and extend further, eventually collapsing. In areas where the subsurface consists of easily dissolved limestone, sinkholes are more common.

Rainfall:
Heavy rains, floods, leaks, or breaks in drainage pipes can allow excess water to pass through the soil, washing out small particles and forming cavities, potentially leading to sinkholes.

Man-Made Accidents:
Aging engineering networks and infrastructure that are not adequately monitored or updated pose potential risks of ruptures and hidden void formations.

Signs of a Potential Sinkhole:
Even if the surface soil appears undisturbed, as the underground cavity forms and enlarges, signs indicating the presence of a void or emerging sinkhole will appear. Recognizing these signs and acting promptly allows for preventive measures, avoiding significant damage to homes, commercial properties, and roads, and minimizing risks to human safety.
What causes voids and failures? What does it look like in practice? We reveal the nature and mechanism of this phenomenon
Don’t face this challenge alone. Get as much information as possible to make an objective decision. From our experience, 2 out of 3 clients who contact us choose to carry out an inspection and review the recommendations.

Don’t put it off — trust the experience and professionalism of our team, and we will help you save and restore what matters to you.
If you’ve reached this section, it means you are ready to take responsibility for the future of your property. We value your care and invite you to take the first step toward saving your valuable asset that is undergoing deterioration. However, don’t rush your decision — your well-being and safety matter.

Start with a minimally required inspection of your building at a reasonable cost to avoid risks and make an informed decision. By obtaining a clear picture of the scale of the problem, you will be able to decide on the next steps. You have three options:
Carefully monitor the progression of damage using professional tools, identifying the “point of no return”
Develop a solution plan taking into account structural, financial, and practical constraints, and implement it
Seek alternative solutions from third parties based on the conducted inspection
Get a free consultation with a geotechnical engineer to discuss your specific case and identify the best solutions
Risks caused by foundation deformation and damage:
Damage to communications that are laid under or near load-bearing structures;
Damage to the building's internal communications;
Damage to load-bearing walls, partitions, and ceilings;
Повреждение систем водоотведения;
Damage to the pavement and external buildings;
Shortening the life of the building;
Pre-emergency condition and the need for unscheduled major repairs;
Inconvenience of building operation and life-threatening conditions;
Heat loss and mold are caused by damaged waterproofing.
