Ultra E3G is a two-component epoxy based product. Which we use for anchoring systems and anchoring iron rods. As you can see, if you want to make a roof extension, if you want to build another floor above the floor, then you have to drill the wall with a drill machine and fix iron rods in it. And the grooves are filled with Ultra E3G so that the joint of the upper building can be fixed with the upper building. Ultra Lock E3G is a durable product that carries the long life reliable results.
