|The new Grout-N-Hopper™ delivery system allows you to grout with just two people.To place grout directly in block, just place the unit above the wall and hold the hose in place. The release of product is controlled by a valve operated by a pendant attached to the end of the hose. Since the person doing the grouting controls the flow, you will have less waste. The standard size Grout-N-Hopper™ delivery system is 3/4 yard, but Push Button Masonry can custom build your desired size. The forklift does all of the lifting, allowing the laborers to stay fresh and more productive.
