# Construction materials: aggregates, block, pavers and crushing Grupo Server's materials and aggregates line manufactures concrete block, pavers and stone aggregates, and distributes construction materials. Promotora Server manufactures structural and facade concrete block, concrete brick and eco-friendly pavers. Triturados Gramol produces stone aggregates —gravel, sand, ballast, base and asphalt mix— at two plants in Coahuila and San Luis Potosí. Vermat distributes construction materials and hardware in Saltillo, an authorized Cemix distributor. This section gathers guides on what these materials are — where they come from, how they are classified and how they are produced — and how to choose, order and verify them correctly before they reach the job site. ## Questions this topic answers - [What is a stone aggregate?](https://gruposerver.com.mx/en/blog/que-es-un-agregado-petreo/) - [What is the criterion for telling sand from gravel?](https://gruposerver.com.mx/en/blog/diferencia-entre-arena-y-grava/) - [How does a rock crushing plant work, step by step?](https://gruposerver.com.mx/en/blog/como-funciona-una-planta-trituradora/) - [What exactly is a quarry?](https://gruposerver.com.mx/en/blog/que-es-un-banco-de-materiales-y-como-se-regula/) - [Are gravel and fine gravel the same thing?](https://gruposerver.com.mx/en/blog/tipos-de-grava-y-sus-tamanos/) ## Stone aggregates: definition, types and calculation - MaterialsSeptember 2, 2026 ## [What is a stone aggregate: definition, types and how it is made](https://gruposerver.com.mx/en/blog/que-es-un-agregado-petreo/) Stone aggregate —sand and gravel— is 60–70% of concrete's volume (GCC, 2020).
