Soils & Aggregate Corrosivity

Soils & Aggregate Corrosivity

Metro Testing + Engineering can determine the corrosivity of soils and aggregates used in construction backfill to provide an understanding of its short-term and long-term effects on metal and concrete structural components such as water mains and utilities, retaining walls, and other civil infrastructure that are in direct contact with backfill.

Corrosivity surveys can be done during pre-construction to provide important baseline measurements, and post-construction to determine current conditions so mitigative measures can be undertaken if necessary. Field services are supported by laboratory testing to provide analytical test data to support our field inspections and assessments.
