0.5” GTI Zero Void® Stressing-End Metal Ring

0.5” GTI Zero Void® Stressing-End Metal Ring
0.5” GTI Zero Void® Stressing-End Metal Ring

The GTI Zero Void® System eliminates the need to fill sleeves (tubes) at stressing-ends with grease as required by ACI and PTI Guide Specifications. The Zero Void® System uses seals to provide thermal tolerance for shrinkage of the sheathing and watertight sealing of the encapsulation.

The Zero Void® Stressing-End Metal Ring utilizes a metal ring with a groove to protect the encapsulation from the heat generated by an oxyacetylene torch. The groove allows the outer lip of Zero Void® Grease Cap to be installed to the proper depth thus allowing an easy gauge of proper cap installation.

The GTI GROUT-LOCK™ Pocket Former, consisting of a pocket former with a lock ring that can be used with the GTI Zero Void® System, is a unique concept to improve the quality and longevity of post-tensioning tendons by providing a mechanical bond that holds the grout plug tightly in place against the surrounding concrete even in less than ideal conditions where the stressing pocket is wet, dirty, covered with grease, or torch residue. The GTI GROUT-LOCK™ Ring has an interior concave surface creating a shear key and slides into position on the GTI GROUT-LOCK™ Pocket Former holding it in place.
