Unstable subsoil? How PUR injections can save your project in record time.

Unstable subsoil? How PUR injections save your project - quickly, safely and cleanly

Blog Accessed: 109

Building subsidence? We stabilize the building ground with polyurethane resin injections - without excavation, without stopping construction.

When the subsoil gives way, buildings, schedules and budgets start to falter. But there is no need for expensive earthworks or months of delays. The solution: PUR injections from SoilTec - fast, precise and permanently effective.

What is soil stabilization with PUR?

The technology is based on expanding polyurethane resin, which is injected into the ground beneath the foundation via small holes. There it expands, fills cavities, compacts the soil - and immediately restores the load-bearing capacity. The injection is targeted and minimally invasive, without the need for heavy machinery or excavation work.

Why PUR injections? Your advantages at a glance.

1. fast implementation - without interruption
The process is carried out precisely, during ongoing operations and without stopping construction. Ideal for buildings, roads or industrial facilities that need to remain in use.

2. clean and quiet - even in sensitive environments
No excavators, no noise, no dirt. This makes the method suitable for listed buildings, city centers or active production sites.

3. sustainable & safe - with tested quality
The PUR resin used is permanently durable, deeply effective and certified environmentally friendly. For long-lasting stability and a good feeling about your investment.

Typical areas of application:

  • Foundation stabilization in the event of subsidence
  • Filling of cavities in the substrate
  • Load-bearing capacity improvement for building extensions
  • Stabilization of traffic areas and industrial sites

When technology meets responsibility: trust the ground beneath your feet

With SoilTec you rely on:

Security - for buildings, schedules and budgets
Reliability - from experienced specialists
Peace of mind - because you know the floor will hold

  • Stopping buildings from settling

    The most efficient method for stopping building subsidence is to consolidate the subsoil using PUR injections. Here, foaming polyurethane is injected into the foundation substrate over several depth levels, restoring the settlement-free load-bearing capacity of the subsoil.

  • Lifting a house out of an inclined position

    Injecting polyurethane into the ground beneath the concrete floor slab increases its volume, allowing the house to be raised above a certain level of ground tension.

  • Increase the load-bearing capacity of the subsoil

    Increasing the structural load increases the soil pressure under the foundation, which can lead to settlement. The load-bearing capacity is increased by injecting PUR into the foundation so that the additional structural load is supported by the foundation without settling.

  • Seal leak in excavation pit wall

    Soil PUR injections are used to seal gaps and unwanted leaks in foundation walls against pressing groundwater. The process is also suitable for creating sealing walls and floors so that, for example, pits for new lift underpasses below the groundwater level in existing buildings can be excavated and concreted without a special excavation pit sealing wall and only with open dewatering.

  • Sealing artesian wells for geothermal drilling

    When sinking geothermal boreholes, there is a risk of artesian seepage, where pressurized groundwater rises from the depth of the borehole. By injecting foaming polyurethane at three depth levels around the borehole, a three-stage sealing collar is formed around the borehole in the injection area, which prevents the water from flowing around the sealing point in the borehole and permanently stops the flow of water rising from the depths.

Our customers are satisfied

 

I would like to thank you for your efforts on the construction site. We very much appreciate the fact that you were able to seal the artesian at short notice.
