The Company Profile

GEOTECNICA CORPORATION (The Rock Engineers) is a 100% Filipino-owned company. Its philosophy in addition to the pursuit of excellence in its field of endeavor, is to promote awareness of the critical role of geology in the design of engineering works and infrastructure for purposes of optimizing safety and economy. Our firm also seeks to contribute to the recognition of the competence and capability of Filipinos.

Since GEOTECNICA was founded in 1978, it has developed a core of professionals with over 100 man-years of experience in geotechnics, engineering geology, environmental geology, seismic engineering and hydrogeology. We have been serving the needs of the mining and civil construction industries in the Philippines and Southease Asta, working in varied and complex geological conditions.

Being a fully self-reliant group, our professional expertise is backed-up by computer technology, an in-house soil/ rock testing laboratory and an array of drilling rigs, in-situ test tools, and geophysical and hydrogeological survey equipment.
