The Silvi Group Companies

NJDOT and PennDOT Certified

NJDOT (New Jersey Department of Transportation) and PennDOT (Pennsylvania Department of Transportation) concrete mixes are certified and closely monitored by the respective states. As an approved provider, Silvi Concrete is equipped to produce mixes that meet and exceed NJDOT and PennDOT standards.
Mixes range in strength depending on the required usage. For example, a bridge deck may require a high performance concrete (HPC), containing superplasticizer, silica fume, fly ash, and blended aggregates. On the other hand, for backfilling a trench, a flowable fill of only sand and cement may be used. All mixes must contain components from a constant and steady source. Stockpiles and silos at a ready mix plant are checked frequently by NJDOT and PennDOT representatives to ensure the materials are up to standards.
