At the end of the forties, a time when the great expansion of the city of São Paulo began with the accelerated growth of industry, river gravel was no longer sufficient to meet market demand. This began the use of crushed stone in the manufacture of concrete. From then on, Izidoro Matheus, who from the beginning was at his brother Antonio's side, had a decisive role in the business. The large-scale production of crushed stone came with the construction of a branch of the Central do Brasil railway line into the quarries, due to the large consumption of the material for the maintenance of its lines.

The manual crushing of stone chips, the mallets and pointers, forged by the hands of Antonio Matheus, the carts pulled by mules, the crusher powered by a steam boiler are today memories of a distant past, of a lot of work and dedication, which served to form the solid and unshakable foundation that currently supports Pedreira Santa Isabel.
