Winslow Stone Depot

H&K Group, Inc.’s (H&K’s) Winslow Stone Depot (formerly Winslow Materials) has been a trusted member of our construction materials family since 2007. H&K’s Winslow Stone Depot was formed to develop a key construction aggregate distribution center or depot in Winslow Township, NJ. Principally established to feed the adjoining Winslow Hot Mix Asphalt Plant with vital construction aggregate materials, the depot also provides vital crushed stone products to customers and clients throughout the central and southern NJ region.


Our crushed stone products are supplied by rail freight from our flagship Birdsboro Quarry operation in Berks County, PA. This facility produces an intrusive igneous rock commonly referred to as Diabase. This extremely hard, crystalline rock is crushed to produce high grade construction aggregate of varying sizes and specifications that is suitable for use in hot-mix asphalt, ready-mix concrete, drainage applications and general construction including railroad bedding. Many of Birdsboro Materials’ construction aggregate products maintain certifications by the Pennsylvania, New Jersey, New York, and Delaware Departments of Transportation (PennDOT, NJDOT, NYDOT, and DelDOT) as well as the Maryland State Highway Administration (MDSHA).

The knowledgeable staff at H&K’s Winslow Stone Depot is ready and pleased to assist you.  If you have any questions regarding products, directions, delivery, or any other general inquiries, please contact the Scale House.
