CONSTRUCTION MATERIAL TESTING SERVICES

GFA has extensive experience providing Construction Materials Testing Services for private developers, municipal departments that manage the construction of public facilities, as well as well as public works and infrastructure improvements project. We understand your continuous need for increased efficiency as well as timely and accurate reporting.
Asphalt
GFA's services are designed to ensure that asphalt products comply as intended. GFA provides asphalt mix designs and verifications, aggregate gradation, stability and specific gravity testing. Field services such as placement inspection, thickness checks, and asphalt coring are also offered.
Concrete
GFA's services include complete testing and inspection of concrete materials. GFA samples fresh concrete for air content, slump, temperature, and unit weight. Samples are obtained for compressive strength results. GFA additionally provides inspection services, floor slab flatness profiling, ultrasonic and R-meter testing and observes concrete placement and provides floor slab flatness profiling.
Soils
GFA provides certified technicians to monitor the compaction of soils by performing on-site tests (e.g. soil density, moisture content, and visual observations). We analyze the suitability of site soils for structural fill and provide recommendations for suggested alterations and equipment utilization. We perform vibro-floatation monitoring and ground penetrating radar as well as other testing services.
