TASK
Determine the depth of weakened soils and level the concrete slabs to the design elevation using injection methods.
TECHNOLOGY
Controlled lifting of slabs and structures by injection of expanding polyurethane.
MATERIAL
Expanding polyurethane — PolyJET FT.
DESCRIPTION
Unstable soils beneath airfield structures cause uneven settlements, leading to operational inconveniences and restrictions for runways, taxiways, and parking areas.
RESULT
Localization of problematic areas using dynamic probing and soil reinforcement in 2- to 3-hour intervals, allowing immediate loading of the pavement after completion of the work.
