PT Tetrasa Geosinindo  >  About us


Established in 1992, PT Tetrasa Geosinindo (Geosinindo) wanted to start right by making sure it does not only have a strong sales force but is strong technically.

Back when Geosynthetic was basically unheard of in Indonesia, a strong engineering team was needed to help consultants with their designs as well as a good installation team to make sure the materials were installed properly. Over the years, more and more new technologies were introduced and Geosinindo also grew in size and quality of the staff and service given to the clients. The company even began implementing its own IT system to manage its growing client database, better logistics system, and many more which is still being improved even now. The installation team grew big enough that it branched off to become its own company which still supports the projects that Geosinindo supplies materials to. The office became too small and has been extended several times to allow for the expansion needed to better serve the clients.

Throughout the years, there have been many changes, personnel and management alike. But the goal remains: Geosinindo strives to engineer the best solutions for the clients through engineering advice, design, supply of the materials, and installation. The values have also remained the same though they are more defined now: Quality, Portfolio, People, Partners, Community, and Environment. Widening the range of the products supplied while making sure of their quality, training our staff and building a good partnership through good and fair practices, helping out in communities and taking our part in caring for the Environment, Geosinindo has been and hope to always will be the role model for its peers in the Geosynthetic and Construction community in general.



The vision of Geosinindo is to be the FOREMOST Geosynthetic Company in Indonesia a
