Superstructure Repair

Diagnosis, Design & Installation
Cavity Wall Tie Installation
Lateral Restraint Installation
Movement Joint Installation
Structural Alterations
Propping Design & Installation

In addition to the installation of Bersche-Rolt’s patented stainless steel reinforced masonry reinforcement systems, our engineer may specify various other remedial measures to repair the superstructure to ensure that the causes of the structural defects are addressed.

These solutions may include the installation of replacement cavity wall ties, lateral restraint systems, remedial movement joints and roof strengthening. We also carry out structural alterations, including the design and installation of temporary propping systems, and the preparation of structural calculations and CAD drawings.

Features:

  • Corrosion resistant high tensile Grade 304 or 316 stainless steel reinforcing bars (1.4301 to BS EN 10088)
  • Reinforcement with a characteristic strength of 500 Mpa (BS 6744:2016)
  • Bars are solid in cross section with a greater cross-sectional area
  • Fixed locating spacers hold the bars centrally in the groove or hole
  • Bars embedded in cementitious, shrinkage compensated, thixotropic bonding mortar with a characteristic strength of 40 MPa
  • Full bridge circumference applications
  • Bars are available in any length and a wide range of diameters from 3 to 24 mm
  • Independently tested by The University of Bradford

Benefits:

  • Significant cost and time savings
  • Reduces downtime and minimal interruption to traffic and services
  • Concealed subsurface installation leaves appearance of structure virtually unaltered
  • Increases load capacity to comply with modern standards with no significant increase in the overall weight of the structure
  • Enables structure to move as a complete unit
  • Whole bridge applications accommodate imposed dynamic and static loads as well as the effects of settlement, thermal and moisture induced movement
  • Superior tensile performance
  • Excellent bond with masonry
  • Ten year insurance backed guarantees as standard
