La utilización de rocas y agregados de las mismas en la construcción se remonta a épocas primitivas del desarrollo del ser humano en las civilizaciones Sumeria y Fenicia, que son las evidencias arqueológicas más antiguas del hombre moderno de construcción de edificaciones utilizando este tipo de materiales. Adicionalmente se tienen las pirámides egipcias y mayas, que son otra muestra del poder constructivo del hombre utilizando los agregados pétreos. Los griegos y romanos edificaron grandes estructuras como el coliseo, el templo de Diana o ciudades como Roma, que hoy son reliquias arqueológicas del desarrollo de la construcción por el uso de agregados rocosos.

Los materiales para la construcción son una serie y cantidad de elementos utilizados en las obras civiles, tales como agregados del tipo piedras naturales y de revestimiento, conglomerados pétreos (arenas y gravas), arcillas, caliza y puzolana para la construcción de cemento, rocas ornamentales para embellecimiento y otras materias primas esenciales para la elaboración de muchos productos de uso estructural en obra gris.

El territorio nacional cuenta con importante cantidad de recursos minerales, los cuales pertenecen al Estado, los mismos pueden ser concesionados siguiendo los lineamientos presentes en el código de minería vigente (Ley N° 6797) y el reglamento al código de minería (Nº 29300-MINAE).  Para proceder con el trámite de concesión es necesario evaluar la disponibilidad del recurso, investigando el tipo de material y la cantidad por extraer, las restricciones presentes en el registro nacional minero que corresponde con áreas de reserva o concesiones ya otorgadas y también áreas silvestres protegidas según el SINAC.

En Geotéctica contamos con un equipo multidisciplinario para realizar la concesión cumpliendo con los estudios de impacto ambiental requeridos.
