Building the digital infrastructure for aggregate commerce.
For decades, aggregate commerce has relied on phone calls, manual quotes, and fragmented local knowledge. We replaced that with software. Today that software powers one of North America's largest aggregate commerce platforms.
About Sand Group USA
A technology and operations company operating in the American aggregate industry.
Sand Group USA is not a quarry, a trucking company, or a materials reseller. We are a technology and operations company. Every system we run — pricing, supplier integration, logistics coordination, customer operations — is proprietary software built specifically for how aggregate commerce actually works.
Delivering bulk aggregates is fundamentally different from delivering a package. A delivered price depends on haul distance, material type, truck capacity, road access, and local market conditions. Availability changes by location. A single ZIP code determines whether a material can be delivered at all. No off-the-shelf platform solves this.
Over the past decade, we have built one of North America's largest software platforms dedicated exclusively to aggregate commerce. Every order processed has made it smarter — creating one of the industry's largest operational datasets for delivered aggregate pricing, supplier performance, and logistics optimization.
How the platform works
Every delivered price on Gravelshop.com is calculated in real time. Our proprietary engine combines the customer’s location, local material availability, haul distance, truck capacity, and supplier economics — and returns an accurate delivered price for every request.
No phone calls. No manual quotes. No price estimates. A customer in rural Kansas gets the same pricing precision as a contractor in Los Angeles — because the engine is the same. Only the inputs change.
Technology
The platform.
Six proprietary systems. No vendor solution existed for this problem — the complexity of real-time aggregate pricing, supplier integration, and logistics coordination at national scale — so we built our own, from the ground up.
Real-Time Pricing Engine
A unique delivered price is calculated for every customer request — combining location, available material sources, haul distance, truck capacity, material cost, and supplier economics. Every calculation runs live. The same precision for a customer in Kansas as a contractor in California.
Geographic Availability Layer
Before any price is shown, our systems determine what can actually be delivered to a given address — querying against 10,000+ supplier locations, filtering by delivery range, capacity, and operational constraints. Customers only see materials that can genuinely be fulfilled.
Supplier Data Infrastructure
We don't list products from a spreadsheet. Every supplier's cost structure, service area, product catalog, loading constraints, and operational requirements is modeled in our platform. That data layer is what makes real-time pricing and availability possible at scale.
Logistics Coordination System
A confirmed order triggers a coordinated sequence: supplier notification, hauler dispatch, route scheduling, and delivery tracking — without manual handoffs. Our operations team handles exceptions. The system handles everything else.
Transaction Intelligence
More than a decade of aggregate transaction data across 31 states. Every order improves pricing accuracy, supplier matching, and delivery performance. That accumulation of operational data is one of the most significant barriers to replicating what we do.
Operations Intelligence
Every active order is monitored, tracked, and managed through the platform. Customer communication, delivery scheduling, exception handling, and resolution are all instrumented — giving our operations team the visibility and automation required to run at national scale.
The technology platform behind Sand Group USA is developed and maintained by Gravel.Group — our European software company specializing in digital commerce, pricing and logistics infrastructure for the aggregate industry across North America and Europe.
Gravelshop.com
Gravelshop.com is the primary customer-facing platform operated by Sand Group USA. It is built for residential customers, contractors and construction companies who need to find, price and order locally available aggregates online.
Customers should go directly to Gravelshop.com to view materials, check local pricing and place orders. The corporate Sand Group USA website is not a purchasing platform.

Operations
National platform. Local fulfillment.
The customer uses one digital platform. Products are sourced and delivered through local suppliers and independent transportation resources — keeping materials close to where they are needed.

Delivered price calculation
Material cost, distance, truck capacity and local conditions are combined into a single transparent delivered price.

Transportation coordination
Independent haulers are engaged to collect from the supply location and deliver directly to the customer's project site.

Customers receive order confirmation, delivery scheduling and status updates through the platform.
Exception management
Our operations team monitors active orders and handles exceptions, delays and delivery issues directly.

Vision
Building the leading digital infrastructure for aggregates in the United States.
Aggregate commerce is a trillion-dollar industry that still runs largely on phone calls, fax machines, and local relationships. Pricing is negotiated manually. Procurement depends on who you know. Logistics is planned load by load. No technology company had solved this at scale before we started.
We are building the systems required to organize this complexity — connecting customers with local supply, automating pricing and logistics, and making bulk material purchasing as straightforward as any other online purchase. Not by disrupting the suppliers and haulers who fulfill every order, but by giving them the infrastructure to serve more customers with less friction.
We have been doing this for more than a decade. That operational depth — the data, the supplier relationships, the platform maturity — is what makes Sand Group USA difficult to replicate. Our goal is simple: build the infrastructure that every aggregate transaction can run on.
