River Rock Industries produces a unique grout plug!

  • Our Margo style grout plugs come without welding of the outlet end washers. We use a pipe flaring procedure instead!

  • Constructed using 100% high performance polyurethane rubber sleeves which are superior to the standard rubber sleeves! We have the ability to vary the rubber sleeve hardness. Need a softer rubber, no problem!

  • We can also provide a fully galvanized unit at only a 10-15% increase in cost over the standard packers!
