Masonry arch bridge repairs

Many of the UK’s 60,000-70,000 masonry arch bridges are well over 100 years old, are often listed structures and urgently require structural repair and strengthening. Age, weathering and increasing loads and stresses have, in numerous cases, led to problems such as:

  • Movement in the spandrel wall
  • Separation of arch rings
  • Cracking in the arch barrel
  • Delaminated masonry
  • Spreading barrels and soffits
  • Cracked abutments and wing walls
  • Spalling brickwork

Helifix has developed a variety of innovative tying, bonding and repair techniques which use its products in appropriate combinations to provide unobtrusive solutions for all such situations where masonry has cracked or failed. These nondisruptive and concealed repair strategies offer savings in both time and money and sympathetically restore full structural integrity.
