PROQUICESA was born in 1969, as a familiar independent company (status that still keeps), manufacturer of construction chemicals, beginning an entrepreneurial trajectory which has been permanently marked for a clear philosophy of rectitude, reliability and total commitment of quality in all spheres of its activity.

Since then, in addition to the experience acquired as a result of the manufacturing and marketing of our own chemicals, the background of PROQUICESA has been enriched with a wide experience of industrial collaboration with some of the most remarkable companies of the sector.

In this sense stands out the agreement with MBT; Master Builders Technologies, (currently integrated in DEGUSSA Construction Chemicals), whose whole range of concrete admixtures marketed in Spain and Portugal was entirely manufactured and quality controlled by PROQUICESA during 1984 - 1993.

At early nineties the interest of our company began to be focused on the market of cement additives, in the context of a progressive strategy of specialization, with the goal of positioning PROQUICESA in some years as technical reference of this field.

Nowadays the cement additives represent around a 90% of the business of PROQUICESA, who has a leader technology in this field and sets up as one of the most innovative companies of its sector.
