Company Profile

1 / History and Philosophy

PT. DUASIA PADUSEJATI is an Indonesian private engineering company established in Jakarta early 1993. The company began as a Civil Engineering Contractor with pile foundation engineering as the core part of the business (manufacturing and installation of precast concrete piles). In line with customers’ requirement, the company also extended the services to some other related fields, such as pile load testing, sub-structure strength-ening (underpinning) and upper-structure strengthening.

Over the last 20 years since its establishment, the company has undertaken many technically chal-lenging projects in various types of constructions and soil conditions; thus accumulated our skills, know-how and experiences in all aspects of our services. The knowledge, skills and experiences gained in this term, combined with the extensive range of innovations in pile manufacturing, pile installation and all extended services have led the company to become one of Indonesia’s respect-able piling companies.
