KASKTAŞ is proud of its lengthy history and is a well-established company, development of which dates back to 1957, coinciding with the foundation of its parent company, ENKA İnşaat ve Sanayi A.Ş., which is currently one of the world’s top general contracting companies. Originally known as ENKA Piling Group, KASKTAŞ’s debut was heralded by the successful completion of its first contract, the construction of the İstinye Bridges on piled foundations. In 1975, after years of rapid growth, the ENKA Piling Group was renamed KASKTAŞ.

Since its inception, KASKTAŞ was conceived to compete and succeed in the international arena. Thanks to its fully owned equipment and its successful management and experienced staff, KASKTAŞ has distinguished itself domestically and internationally by closely following developments in geotechnical engineering and advancing its know-how and capabilities accordingly. Today KASKTAŞ is not only the leading geotechnical engineering company in Turkey, it is a leader in its foreign markets as well.

Despite its dominance as one of the first geotechnical engineering contractors established in Turkey, KASKTAŞ took the iniative and extended its interests into foreign territory in 1980. Its initial contracts were in Saudi Arabia and the Gulf countries, and later it expanded its project experience into the CIS and Russia. Since early in the new millennium, KASKTAŞ has further expanded into Kazakhstan, Azerbaijan, Georgia, Ukraine, Bosnia Herzegovina, Libya, Djibouti, Albania and Algeria.

In addition to the invaluable contribution made by its highly skilled technical and managerial staff, KASKTAŞ owes its respected reputation to fulfilling its responsibilities on time; preparing the most appropriate solutions and economical designs for its clients and successfully accomplishing its applications according to ISO 9001 Quality Management, ISO 45001 Occupational Health & Safety Management and ISO 14001 Environmental Management Standards.

Ever since its inception as ENKA’s ground engineering and foundation contracting company, KASKTAŞ has continued to grow and prosper, enlarging both its capacity and its know-how.
