The Challenge
Unreliable footage, reactive coaching, and rapid fleet growth created safety and potential litigation risk
Silvi Materials is one of the East Coast's leading independent construction materials suppliers, delivering ready-mix concrete, aggregates, and bulk materials across Pennsylvania, New Jersey, North Carolina, Ohio, Delaware, Maryland, and New York. With over 600 vehicles operating daily around the country, the stakes for fleet safety have always been high. Before Samsara, Silvi Materials relied on a dash cam provider that routinely failed to deliver on the most basic requirements: footage from safety events was often unavailable or took days to retrieve, vehicle health reports inaccurately reported camera status as operational when equipment had actually failed, and driver coaching was reactive by necessity—managers couldn't hold drivers accountable to data they couldn't trust. And when Silvi Materials began accelerating its acquisition strategy, adding over 200 new vehicles from two separate fleet acquisitions, the challenge of safely integrating drivers with different safety baselines and cultural norms into a single, consistent safety program became more important than ever.
"We haven't had any issues with the union about Samsara AI Dash Cams. That's because our dash cam privacy policy is even stricter than what their union contract requires. Our dash cams are genuinely protecting our union drivers."

The Solution
Samsara delivers an 80% reduction in incidents and protects yellow iron from theft and loss
Silvi Materials deployed Samsara AI Dash Cams and Vehicle Gateways across its entire fleet, digitized DVIRs, used Asset Tag to protect yellow iron from theft and loss, and leveraged Automated Coaching to empower drivers to coach themselves in the cab. In three years, Silvi Materials scaled their safety program through two major fleet acquisitions, quickly and easily onboarding over 200 vehicles with Samsara technology.
Silvi Materials prioritized driver trust from the start of their partnership with Samsara, using in-cab alerts for real-time coaching and implementing a "grace period" for newly acquired fleets to correct behavior before escalating interventions. This intentionality, coupled with the full Samsara Connected Operations Platform, resulted in strong union and driver buy-in for Samsara and Silvi Materials's safety program.

Achieving a 4x increase in coached events without adding to manager workload
AI Dash Cams have transformed both claims exposure and driver safety outcomes for the Silvi Materials team. In a single head-on collision, Samsara HD Dash Cam footage proved the Silvi Materials driver was fully in his lane and had responded correctly to another driver, saving the company an estimated seven figures in litigation costs. With Samsara Automated Coaching and in-cab alerts, Silvi Materials was able to rapidly and efficiently scale their coaching program with a 4x increase in coached events in 2025—without adding to manager workload. With this technology-driven coaching shift, Silvi Materials drove a 97% decrease in rear-end collisions, a 25% reduction in overall safety events, and an 18% reduction in at-fault incidents, even as they absorbed over 200 new vehicles through acquisition.

Samsara Platform
Automated DVIR-to-work-order workflow eliminates missed maintenance flags and keeps equipment hours accurate
Before Samsara, Silvi Materials' maintenance program depended on paper logs and hand-keyed data into their shop system. Defects were easy to miss, hours were often wrong, and technicians rarely had a complete picture of a vehicle before opening a work order. With Samsara capturing DVIRs, photos, defects, and accurate engine hours directly from the asset, Silvi Materials now runs maintenance off a single, trusted stream of real-time data—regardless of which shop system they use to manage work orders.

Asset Tag
Recovering $210K in stolen assets from one incident and eliminating lost hours with Asset Tag
Silvi Materials manages a massive, multi-million-dollar inventory of equipment across sprawling operations—including a 1,400-acre stone quarry, three sand mines spanning 3,300 acres, and dozens of ready-mix plants. By deploying Samsara Asset Tag across their trailers and assets, Silvi Materials has transformed their daily logistics, eliminating countless hours previously wasted searching for misplaced trailers and small assets, streamlining maintenance road calls, and providing critical discreet tracking that enabled the immediate recovery of $210,000 in stolen vans and trailers.
