DD Grout Plugs specialises in developing innovative hole blocking techniques to cap off diamond drill holes and control high pressure water. Our Hydra-Barb Technology (TM) plugs are rapidly becoming the standard for some large blue chip underground mines in Australia and overseas. They are the only load and pressure rated plugs available to diamond drillers, rated to 1000 psi (69 bar) at a factor of safety of 2:1. Simple. Safe. Efficient. See www.ddgroutplugs.com
