Keystone Material Testing has engineering technicians who have been
previously employed by other firms, thereby starting with personnel who
have the experience, as well as desire, to support those aspects of the
construction project that deal with natural and man-made materials.
They will serve as an extension of the Architectural, Civil, Structural,
Mechanical, Electrical, Environmental and Survey services of the parent
firm.
The firm adheres to the highest professional and ethical standards, such
as membership in the Central New York Chapter of the American Concrete
Institute. Technicians engaged in concrete testing are trained and
certified under the ACI program. The goal is to provide professional
construction materials testing services, principally throughout the
southern tier of New York State.
