Durability Engineers PLLC

Consulting services to identify, assess, and address concrete durability risks across new construction and existing assets, focusing on exposure conditions, deterioration mechanisms, constructability risk, and service life performance.

• Durability Planning

  Pre-construction planning to align durability objectives with exposure conditions, performance requirements, and maintenance expectations. Services include durability risk matrix development, specification language, thermal and cracking risk reviews, and construction quality recommendations.

• Durability Assessment

  Evaluations during design and construction to document and track durability risk, including review of drawings, mixture submittals, construction records, and nonconformance evaluations.

• Durability Intervention

  Field assessments, nondestructive testing, selective sampling, and laboratory analysis for existing structures showing distress or deterioration to evaluate service life, develop repair strategies, and design monitoring plans.

Deep-expertise consulting for complex concrete pathologies that cause premature structural failure, combining field investigation, laboratory testing, and tailored mitigation and repair strategies.

• Alkali-Silica Reaction (ASR)

  Prevention, evaluation, and repair services for ASR-affected structures, including petrography, standardized and specialty testing (such as ASTM C1778), project specification development, on-site evaluation, nondestructive testing, monitoring plan development, and mitigation design.

• Delayed Ettringite Formation (DEF)

  Investigation, risk assessment, and management of early-age heat exposure risks in new concrete and existing structures, utilizing material chemistry assessments, petrography, expansion testing, and field documentation of distress patterns.

• Pyrrhotite Analysis

  Field and laboratory evaluation of iron sulfide-bearing aggregates, including testing in accordance with CSA and ASTM standards (such as CSA A23.1:19 P2/P3, ASTM C295, and ASTM D4239) to diagnose deterioration, assess risk, and design mitigation strategies.

Work in this area is organized into supported delivery tasks.

• Work In This Area Is Organized Into Supported Delivery Tasks

  Support includes Work in this area is organized into supported delivery tasks.

Petrographic examination of concrete core and aggregate samples in specialized laboratories for the characterization and diagnosis of deterioration mechanisms such as ASR, DEF, and pyrrhotite oxidation.

Assessment and repair design for concrete structures experiencing deterioration or distress. Services include condition assessments, repair strategy development, repair design, construction administration, and construction oversight.

• Repair Strategy Development

  Developing comprehensive mitigation and repair strategies tailored to specific concrete distress mechanisms and client requirements.

• Repair Design

  Designing structural repairs and external confinement, such as post-tensioning and fiber reinforcement, to extend the service life of concrete elements.

• Construction Administration

  Providing administrative support during the repair construction process, including regular communication and performance tracking.

• Construction Oversight

  Delivering field oversight during the execution of repairs and mitigation strategies to track performance and ensure specification compliance.
