Our Spin Casting Procedure
Spin Casting is the latest in remediation technology for Medium to Large diameter storm water infrastructure, using our High Strength Micro-Silica Structural Mortar. This straight forward Cast-In-Place Culvert renewal method has been developed to accomplish these critically important factors… 1) avoid excavation, and 2) achieve the desireable long-term service life that was formerly associated with high-cost replacement construction. This Cast-In-Place Cement process will also achieve complete structural renewal from our specialty materials, developed through proprietary blending of special cement ad-mixtures, in combination with a Portland Cement platform, producing a High Strength and Very Workable Structural Mortar. Micro-Silica fume is a key component to making Centrifugally Cast-In-Place Cement the most advanced culvert restoration solution for compromised structure. Application in CMP structure typically includes Shot-Crete Spraying and hand trowelling,to fill the corrugation, along with the centrifugal application phase. Three fundamental properties of our High-Strength Mortar are foundational in the success of Cast-In-Place Culvert Renewal, 1) the highly abrasive resistant nature of our cured concrete, 2) extremely low permeability and 3) very-high compressive strength, as validated in laboratory cube break testing.
The real attraction to our “Spin Casting Method” is the uniform build of our New-Cast-Pipe thickness, made possible through the application process of the structural cement being uniformly applied around the culvert circumference, generating a “Structurally Sound Monolithic Casting”. This centrifugal casting system approach achieves this uniform material application from constant material delivery over the entire culvert length. Please Note: For the purpose of consideration as a culvert rehab process perspective, Spin Casting simply utilizes the existing pipe as the form for our unique Cast-In-Place procedure. Optional spray-on epoxy finishing can provide the necessary barrier to protect against MIC (Microbial Induced Corrosion) as found in harsh sanitary sewer environments. Our specially developed Epoxy formula is designed to bond extremely well with our Micro-Silica cement, boosting the water flow dynamics by lowering the Manning N values. Another Giant Consideration for our “Cast-In-Place Cement Method” is our work staging area requirement is less than half of the work staging area required by other relining method systems. With this nice convenience made possible from our modest equipment needs, we are rarely even hindered, when limited access to a structure has completely eliminated all hope of other rehab methods even getting near the project structure.
