  • 2020 Green Initiative

Westbrook Concrete Block’s 2020 Green Initiative is our commitment to providing the same high-quality products we have for over 70 years while limiting our carbon footprint.

  • Pozzotive®

    Pozzotive is a high-performance pozzolan made from 100% post-consumer recycled glass. Glass is diverted from multiple post-consumer waste streams, including bottle redemption and curbside pickup, processed to remove all organics, and then milled to a precisely graded, powder-like substance in a size appropriate for Portland Cement replacement. Pozzotive can be used in a multitude of our products, such as our structural grey CMU, along with our entire line of architectural CMU and WESTBRICKS.

    With the introduction of Pozzotive into our manufacturing process we have seen significant improvements in the quality of our CMU. This post-consumer material, while meeting or exceeding all ASTM standards, has created a stronger and denser CMU that provides a lower permeability rating than the industry standard.

  • Innovation

    We have been innovators in the concrete block industry for over 70 years, always searching for a way to improve the manufacturing process of the concrete masonry unit (CMU). We strive to meet the needs of our customers by responding to current architectural trends with the development of new finishes and products. With the introduction of Spectra Glaze by Westbrook Concrete Block, Omni Block, and WESTBRICKS, we continue to be an innovator in the industry.
