Load Integrity

To assure load integrity, CR Minerals uses only high quality pallets with heavy duty cardboard liners to protect the bagged material from the pallet. We take great care to assure that each pallet of paper bags is stacked squarely. All paper bag loads are shrink-wrapped. Great care is taken when loading vans and containers to assure that the load is evenly distributed. CR Minerals encourages its customers to request single stacked pallets in order to assure proper load integrity in transit.

CR Minerals Mine grades are shipped directly from our pumice mine in bulk trucks. Since CR Minerals mine pumice is very light in weight, typically less than 35 lbs. per cubic foot, our sales and customer service staff works diligently with customers and trucking companies to assure that high cubic capacity trailers are used in order to achieve maximum legal weights loaded on the trucks.
