Imagine what you can build. With Solite®, architects and engineers create buildings that stretch the imagination and stand the test of time.  Northeast Solite has seven decades of world leadership in process innovation, construction application, and design of lightweight aggregate concrete.

Our products and processes give concrete structural efficiency, high strength, durability, predictability, low permeability, fire resistance, and energy savings. Our materials are readily available for transport by utilizing any of the superior logistical capabilities available at our production facilities. Served by direct Class 1 railroads with all carrier connections, overland truck, Greater Inland Waterway (GIWW) barge, Intracoastal Waterway barge, and by Ocean transport, our products are easily distributed and available for your next project.


We judiciously select raw materials that possess unique physical characteristics to produce our high performance, rotary kiln expanded shale aggregates. The extreme heat makes our unique shale raw material expand and bloat creating a new ceramic product that is both stronger than common shale and 30% lighter by volume.

In our manufacturing process, kiln temperatures of 2100°F are carefully maintained and monitored. Our lightweight aggregate is then cooled and sized to ASTM (C330 and C331) and other customer specification.
