Runway subsidence

The fast, non-disruptive solution for taxiway and runway subsidence

Airports are an integral part of UK’s transport infrastructure and contribute significantly to the country’s economy. As the aviation industry operates according to complex air traffic management systems, any infrastructure failure can lead to costly disruptions. Runway subsidence has a critical operational impact.

Mainmark’s fast, non-disruptive, and economical solutions and technologies are particularly well suited to address the complex challenges of airport pavement, taxiway, runways and airport building repair, including:

  • The filling of voids directly beneath pavements to reconfirm support and limit deflection and deterioration
  • Raising subsided pavements runways to re-establish design levels and/or drainage gradients
  • Providing targeted ground improvement to weak subgrade soils
  • Raising and re-levelling of airport buildings

The fast, non-disruptive solutions for UK’s airport and runway subsidence.

Slab lifting process for airport runways

Small holes are drilled through the slab.

Multi-component strcutural resin is injected. It expands immediately, filling any voids and compacting the substrate.

After re-supporting the slab, continued injection raises it, guided by the laser level.

The treated pavement sections are returned to full operation immediately after the repair work, and no curing time is required.

Teretek® resin injection is a technology that has been qualified, tested, and adopted by infrastructure authorities around the world

Since 1989, Mainmark has been successfully delivering its resin injection products and methods to support and re-level subsided runways and structures, as well as strengthening the subgrade soils often associated with pavement failures at airports.

Teretek® resin injection is a technology that has been qualified, tested, and adopted by infrastructure authorities in the UK and around the world.
