Our Airfield Maintenance teams carry out works on civil, military and private airfields in the UK and abroad.

Using specialist materials, we undertake:

  • Flexible concrete repairs which flex with the pavement movement, thereby reducing cracking and lasting longer
  • Asphalt repairs which require no compaction so small sizes repairs can be undertaken without FOD risk
  • Extruded fuel and non-fuel resistant joint sealing works for concrete and asphalt
  • Unique recessed joint repairs ideal for runways and taxiways
  • Performance joint repairs between asphalt and concrete
  • Asphalt preservation where asphalt surfaces are treated with a proven preservative to extend the life of the surface, hold together surfacing fines and reducing FOD at a fraction of the cost and time associated with a resurfacing intervention
  • Concrete protection and preservation
  • Ironwork reinstatements

Allied are often called upon to provide pre-design, planning and programming of airfield works services and are happy to engage with our Clients to provide this.

We are also able to undertake airfield marking operations, and can provide a full airfield maintenance operation including cyclical tasks such as snow clearing, de-icing and grass cutting.
