LOCATION: Geneva Airport, Switzerland
YEAR: 2008

Over time, aeroplane loads had led to a non-uniform subsidence of the reinforced concrete slabs in some areas of the runway and aeroplane parking areas, provoking hazards and unacceptable height differences between the slabs.

Why the customer chose Uretek:

• Speed: Careful planning and programming of the times allowed the work to be completed in a relatively short time;

• Competitive prices;

• Non-invasive: The intervention did not dirty the area or produce waste;

• Continuous monitoring of the work: The activities were subject to real-time laser control by highly qualified personnel;

• Application of the exclusive Uretek Floor Lift® technology: A special expanding resin with high swelling pressure is injected into the soil, compacting it and stabilizing the structures;
• Respect for the environment Above-ground mixing of the Uretek® resin creates a final inert product that does not release solvents into the soil or possible water tables in the area.

We used the Uretek Floor Lift® technology, designed specifically to solve these types of problems. Injecting a special expanding resin into the soil under the concrete base of the slabs, we filled the voids and reinforced the underlying terrain. Once full contact between the paving and subgrade had been restored, the resin continued to expand, lifting the paving and recovering its flatness.

Observations
We have performed maintenance regularly on various areas of the Geneva airport runways since 1997. We consolidated the soil under the paving in various areas in 2002 and 2008, always with success.
Among the many advantages offered by the Uretek Floor Lift® technology, the possibility of using the treated area immediately after the intervention is much appreciated.
