Subsurface Technologies

STI was founded in 1998 by two professionals with working experience in environmental and construction issues. They are highly respected as business and professional leaders. In a short time, STI is attaining a growth rate that attests to the success of our approach - know the customers and work hard to earn their trust. Continued growth is controlled and generated from within to assure reliable and consistent management and technical support. In a market subject to changing regulations and priorities, STI is committed to determining the best and most cost-effective plan of action. STI's approach is practical, relying on the most appropriate technologies, and using common sense experience gained in the field. STI works with clients and other contractors to treat environmental issues as a corporate business element rather than an expensive, unexpected add-on cost.
