Durability Engineering

Solutions for preventing and treating corrosion damage to steel reinforcing bars in concrete and structural steel.

Damage evaluation and recommendations for remedial works to ensure durability, including

  • Development of testing programs to check the effect of leakage on the durability of reinforced concrete

  • Assessment of concrete substructures exposed to groundwater due to construction delays

  • Comparison of refurbishment options to demolition and reconstruction

  • Building service life prediction using established industry standard software packages, such as life365

 

Development of repair solutions, including

  • Maintenance plans for old buildings with structural issues, including short- and long-term repairs and safety measures

  • Repair specifications and strategies that account for building use and access restrictions

  • Compliance with the latest European standard EN 1502 reinforced concrete repair protection philosophies

 

Advice for reinforced concrete and structural steelwork, including

  • Development of testing programs to check the effect of leakage on the durability of reinforced concrete

  • Assessment of concrete substructures exposed to groundwater due to construction delays

  • Comparison of refurbishment options to demolition and reconstruction

 

On dilapidated old buildings YECS can carry out a comprehensive Cost Study to make the comparison between

Repair vs. Demolition to establish the building Life Cycle Cost

 

YECS provides expert advice on all aspects of concrete technology, including: mix design, materials, testing, construction techniques, strength, durability, permeability and serviceability.

 

YECS has provided the following services on varied projects and to different industry sectors for CONCRETE TECHNOLOGY on mass concrete, reinforced concrete, post tensions concrete, prestressed concrete and precast concrete:

  • Recommendations regarding failure of production concrete strength tests

  • Statistical analysis of concrete strengths

  • Development of non-destructive and destructive testing to assess concrete strength relative to contracts and recognized international codes

  • Investigation, assessment, and recommendations for cracking of concrete elements

  • Investigation, assessment, and recommendations for defects such as voids/honeycombing in concrete construction

  • Recommendations for performance criteria for concrete permeability

  • Recommendations for hot weather concreting measures

  • Recommendations for mix design, materials, and application of high-quality concrete finishes

  • Quality and Integrity Survey of new concrete construction

  • Advice on destructive and non-destructive testing programmes

  • Investigation, assessment, and recommendations for cracking of precast concrete elements
