Restoration of a metal aqueduct over 80 years old was provided by KALMATRON® KF-A as an admixture to the fine plaster mix to provide adhesion to the rusty old metal and brand new one as well.
The 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/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.
KALMATRON® PLASTCRETE
Over 80 year old aqueduct metal pipe (at left) and modern one (see above) are prepared to resist rust and to prevent the contamination of water.
Regular mortar pump provided efficient PLASTCRETE application with slump at 2" (50 mm).
Extremely rusted and even "fossilized" parts of old pipes were cleaned by a spinner, wisely designed and perfectly made by "Shotcrete Technologies Inc."
After that the same spinner is used for PLASTCRETE application. This well made machine is a guarantee of continious and permanent thickness of PLASTCRETE application.
Initial spray of PLASTCRETE on wall of metal aqueduct.
PLASCRETE applied on a wall with thickness of 15 mm.
PLASCRETE applied onto the ceiling of a metal pipe with thickness of 15 mm.
The slopes and elevations of the metal aqueduct required PLASTCRETE pumping on 6,000 ft (200 m) with slump at 2" (50 mm).
