What KASKTAŞ does

KASKTAŞ (legal name: KASKTAŞ Kayar Kalıp Altyapı Sondaj Kazık ve Tecrit A.Ş.) is a Turkey-based geotechnical engineering and deep foundation contractor founded in 1957 and operating as a wholly-owned subsidiary of ENKA İnşaat ve Sanayi A.Ş., a Borsa İstanbul-listed conglomerate. The company delivers specialized construction services across deep foundations (bored piles, driven piles, secant piles), deep excavation support (diaphragm walls, anchored systems), slope stabilization, soil improvement (jet grout, deep soil mixing, stone columns, vibro compaction), and marine works (quay walls, breakwaters, cofferdams). Its proprietary innovations include K-CELL, a bi-directional static axial load testing method developed in-house since 2018, and SBMA (Single Bore Multiple Anchor) high-capacity anchoring technology.

The company maintains a 101–250 employee workforce and operates from an Istanbul headquarters with regional offices in Moscow (Russia) and Jeddah (Saudi Arabia, via Kasktaş Arabia Limited), executing projects across Turkey, Russia, Saudi Arabia, Bahrain, Morocco, Iraq, and the Bahamas. It owns and operates specialized equipment including the Bauer MC96-BC48 HDS-T Hydraulic Cutter, deployed at the Akkuyu Nuclear Power Plant. Notable reference projects include the 1915 Çanakkale Bridge Europe Anchor Block, the NEOM Trojena Time Travel Tunnel (Subcontractor of the Year 2024), the ENKA Kırklareli Natural Gas Combined Cycle Power Plant, the BMT Container Terminal in Iraq, the Masar Project in Mecca, and the Nassau Cruise Port in the Bahamas.

KASKTAŞ generates revenue through project-based B2B contracts as a specialist subcontractor or direct geotechnical contractor, acquiring work via competitive tenders and direct negotiations with project owners, general contractors, and government entities. Pricing is not publicly disclosed and is determined per project through competitive bidding. The company markets primarily through industry conference participation (ZMGM, DFUI MENA, NPPES, EFFC), multi-language corporate communications, and reputation-driven referrals from named enterprise clients including ENKA, Ant Yapı, Ferrero, and Almoosa Health Group.
