The contractor of choice for foundation and geotechnical works in the Kingdom of Saudi Arabia

TREVI ARABIAN SOIL CONTRACTORS is a full-service ground engineering and contracting company providing expertise in a broad range of technologies and innovative solutions towards utmost customer satisfaction.

ARABIAN SOIL CONTRACTORS (ASC), based and registered in Saudi Arabia as a limited company since 1975, was acquired by TREVI Group in 2008.

ASC was founded as an SFI (Saudi Lebanese Foreign Investment Company) by SOLTRAVO-Lebanon. Upon its inception, ASC made an imprint as a pioneer foundation company as it launched the first deep foundations and diaphragm walls executed in Saudi Arabia and Gulf Area.

Throughout the ’70s, ASC was involved in the construction of the main high rise buildings in downtown Jeddah, such as the Queen’s Building, a city landmark and breakthrough in deep foundation technology which to this day remains an emblem of engineering proficiency.

During the late 70’s and early ’80s, ASC actively expanded its presence in the Kingdom and know-how in new technologies through an international partnership which laid the ground for enhanced professional expertise. In the late ’90s, ASC merged with NCF under ASC name and became an entity within the Saudi Binladen Group. The merger widened further ASC’s area of operations as it implied a permanent presence in the Western and Eastern regions of the Kingdom.

Today, under its new name “TREVI ARABIAN SOIL CONTRACTORS” (TASC) associated to the recent acquisition, the Company is a mature foundation contracting and geotechnical engineering firm, strongly rooted in Saudi Arabia and benefiting from the broad backup and international expertise of the TREVI Group.


To provide safe and quality work throughout Kingdom of Saudi Arabia, expecially in those challenging project where our experience and core values make the difference.
