Restoration of a metal aqueduct over 80 years old was provided by KALMATRON® KF-A as an admixture the fine plaster mix to
provide adhesion to the rusty old metal and brand new one as well. Shotcreting efficiency with PLASTCRETE mortar, developed
by our company, for applications on the surfaces made from stone, concrete, metals and polymers, has been tested over the last
12 years on the structures of water supply, sewage, chemical and agricultural industries.
This mix design contains an additive KALMATRON® KF-A, which is designed to ensure a complete hydration of cement with the
subsequent hardening into a solid cement stone, which does not have secondary reaction products with water or corrosive
environment. Therefore, there are no “sources” for corrosion and thermal disintegrations (see "UNIQUE ENGINEERING").
Application was provided by the staff of the "Department of Water & Power of the City of Los Angeles." The main goal was to repair the internal side of the metal aqueduct to protect the metal surface from rusting. Mortar mix design PLASTCRETE was developed to achieve significant adhesion to the metal and provide water impermeability to the metal surface.
The simplicity and efficiency of the equipment and the admixture to the PLASTCRETE mix KALMATRON® KF-A allowed to restore and provide water impermeability without any other chemical agents. With limited time per shift, it greatly economized labor' expenses and construction time.
Highest performance of successfully designed and applied PLASTCRETE classifies it as a protective remedial layer with effectiveness of sophisticated coats and simplicity of stucco application.
Extremely rusted and even "fossilized" parts of old pipes were cleaned by a spinner, designed and made by "Shotcrete Technologies Inc." After that the same spinner is used for PLASTCRETE application.
This well made machine is a guarantee of continuous and permanent thickness of PLASTCRETE application. Particular areas were lined manually by the nozzleman' crew.
