Glass Mountain Pumice, now part of Monarch Mountain Minerals Aggregates LLC, has been a leading producer of high-quality lightweight aggregates since 1977. Located near Medicine Lake in Northern California, the company utilizes a natural volcanic deposit to mine and process lightweight pumice for various industrial applications across the Western United States. The company's lightweight pumice offers numerous advantages, including a lower carbon footprint compared to traditional aggregates and a natural off-white color that reduces the need for coloring pigments. Glass Mountain Pumice products, such as Lite-Rock, are labor-efficient and cost-effective, providing excellent fire endurance ratings for structural concrete and other building materials.

Mobile mixers are capable of creating concrete directly on the job site, rather than mixing it and then transporting it. This prevents the concrete from aging during transport and helps avoid the cost of mixing too much excess concrete.
