SURFACE REPAIRS
SURFACE REPAIRS options
When a crack or joint defect goes beyond surface sealing, the pavement itself needs to be repaired. Shepherd & Sons carries out structural surface repairs on both asphalt and concrete surfaces, using industry-proven materials suited to the most demanding environments including airfields and highways.”
Sealing or a structural repair
Most surface defects start as a crack, and most cracks can be sealed. A repair is needed instead when the material either side has failed: asphalt that has broken up or lifted, or a concrete bay that has lost its support and moves under a wheel. Sealing or overbanding over that only delays the work, so the surface is assessed first and the report says which it needs.
For asphalt we use ArmourScreed, and for concrete, including runway, taxiway and apron bays, Maxi-Crete, which gains strength quickly enough to reopen a bay within hours. Where an airfield slab is losing its surface but is sound beneath, a resin concrete airfield repair may be enough. Where the crack is still sealable, see crack chasing and overbanding.
ArmourScreed
ArmourScreed is used for repairing defects in asphalt surfaces. When a crack in asphalt reaches the point where it can no longer simply be crack-chased or overbanded, for example where a section of surface has become an isolation point and could lift under load: Armourscreed provides a structural repair solution.
Applications: Asphalt Surfaces
Surface repair contractors in Kent and across the UK
We are based at Little Westerhill Farm near Maidstone in Kent and carry out structural concrete and asphalt repairs nationwide. A bay repair is bought against a closure rather than a working day, because the material has to be placed, finished and left to gain strength before traffic comes back onto it. The South East is served from our own yard, and anything longer or further afield is mobilised as a national programme.
Maxi-Crete
Maxi-Crete (Concrete Surface Repairs) Maxi-Crete is used for repairing defects in concrete surfaces. Where a concrete joint or crack has deteriorated to the point where a bay could become unstable, particularly dangerous on airfield pavements where a loose slab beneath an aircraft is a critical safety issue: Maxi-Crete provides a rapid, durable repair.
Applications: Concrete runways, aprons, taxiways, industrial floors, ports.
