Bersche-Rolt’s holistic structural repair process is central to our approach for the repair and protection of concrete structures, in accordance with the principles laid out in European Standard EN1504.

We diagnose the cause of defects in concrete by undertaking a full range of investigation and testing techniques, as specified by our engineer. These may include a defect location and hammer test survey, cover meter survey, carbonation depth and chloride tests.

Once the cause and extent of the damage has been established, we will specify an appropriate repair scheme, which may include a range of concrete repair, corrosion prevention and protective coating techniques - all undertaken by our specialist site workforce.

We are members of the Concrete Repair Association and have successfully completed an extensive range of concrete repair projects since we were established in 1992. In 2015 we won the Repair & Refurbishment category at the Concrete Society Awards for the diagnostic, concrete repair and coating works we undertook to Barry Island’s iconic Eastern Shelter in South Wales.

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
