How To Pre Cast Concrete Walls Created to Rebuild New Orleans

Specifically designed for concrete casting, VytaFlex™ 60 can be used to pour large amounts of concrete without distorting the casting. Having exceptional dimensional stability, the VytaFlex™ 60 will accurately maintain all elements of the original model.

Because of the large amount of rubber required to complete this liner (1500 pounds), the EZ Meter Mix machine is used as a mixing and delivery system for the rubber onto the original model. This machine uniformly mixes the VytaFlex™ 60 at a ratio of 1A:1B by weight. The end result produces a formliner with no air bubbles, making it much more durable and increasing the number of castings that can be poured into it. After proper setup of the EZ Meter Mix machine, it dispenses a small amount of material into a waste bucket. This is done to ensure proper mixing and calibration of A:B ratio.

Filling into the mold box is begun, making certain to dispense into the lowest point. This allows the rubber to naturally seek its own level over the model and displace air while doing so. A minimum thickness of ¾” (1.9 cm) is maintained on sidewalls and over the highest points of the model.

Higher temperatures will cause the rubber to cure faster, cooler temperatures to cure slower, however a minimum of 65F is required to ensure proper cure of rubber. The VytaFlex™ 60 must cure for 16 hours at a temperature of (72F / 23C).
