Mix It, Pump It, Deliver It
Masonry contractors looking to improve the way they mix, pump or deliver mortar or grout will find a range of new and upgraded machines. For example, Waterford, Ohio-based EZ Grout Corp. has a new mixer – The Big Mixer – that mixes large batches of abrasive material quickly, says Damian Lang, company owner and president.
“It was designed to be used 24-7 in plants and has a hardened liner that can be replaced,” Lang says. “Unless a contractor is mixing very low viscosity or abrasive materials in large batches, it is much more mixer than what is needed on the average construction site.”
“I wanted to make a new mixer for the masonry industry that sits low to the ground and has a hydraulic dump for pouring into a wheelbarrow or a mud tub,” Birmingham says. “This is the first mixer that sits low to the ground. It’ll be easier to load with a lot less waste. It also offers better ergonomics for the workers.”
The mixer is designed for ease of use without extra features that would increase the cost. “You pull a lever and it dumps all of the load. It’s really simple to use without a lot of bells and whistles,” he says.
The company also offers a better wheelbarrow. “Other wheelbarrows are all bolted together. After a month or two, the bolts start to come loose,” he says. “Our frame is all welded together so there’s nothing to come loose.”
Faster delivery, simple cleaning
The angled discharge snout lets masonry contractors grout closer to the ceiling on interior walls, while using less forklift boom on high walls.
“Anytime you can save boom extension, it is very beneficial for the forklift operator as it keeps the load more stable,” Lang says. “The new hopper tilt feature on the Uphill Grout Hog saves the forklift operator time by sitting the machine on the ground and letting a laborer simply tilt the hopper and remove the auger to clean. Therefore, this allows the forklift to be utilized on other parts of the masonry work while the cleaning process takes place.”
Designed to unload grout twice as fast as other systems with virtually no plugging, the machine is simple to operate.
“The auger size has been increased to carry more than twice the amount of grout through the tube and into the walls. This allows grout to flow freely without putting high maintenance rubber paddles on the flighting,” he explains. “Therefore, the machine can run for years with minimal, if any, auger or tube maintenance.”
Straightforward labor saver
“Our system is completely self-contained. The contractor never sees the product in the dry form. They see the final product coming out of the hose,” says Arnold Germann, president of the Antioch, Ill.-based company. “The refilling of the silo is done by cement trucks. There’s no pallets; no bags. That’s why we feel it’s the cleanest system on the market. There’s no dust blowing around.”
Masonry contactors can attach a mixer or a pump to the silo. The system also ensures a consistent color throughout the job.
Filling a niche
“The PumpMaster offers an advantage over other methods used to fill block in the industry. It fills block without the need of a forklift or full-size concrete pump, saving a lot of labor and equipment cost,” he says.
A 25-horsepower Kohler engine pumps materials over longer distances on the jobsite, Ferguson says.
Livonia, Mich.-based Grout Grunt offers a low-tech solution for grouting. The Grout Grunt places grout up to 50 percent faster than other methods, says Morgan Agazzi, project manager.
The Grout Grunt’s easy-to-pour mouth provides more precise pours, so the grout doesn’t run down and stain the wall, he says.
“It has the funnel incorporated into the mouth for accurate pours,” Agazzi says. “It’s a big factor with colored mortar. It eliminates spills and waste.”
Portable pump advantage
“This is for specific applications for a specific job. After the job is done, the pump may sit on the shelf for a year before you have another job for it,” Rountree says, noting that the pumps should be stored out of direct sunlight, since ultraviolet rays can affect the diaphragm.
Kenrich’s newest pump, the GP-8A, is an air-powered, twin diaphragm pump that offers an output capacity of up to nine gallons per minute.
“The advantage of a twin diaphragm over a single diaphragm is it does not increase your pressure, but it effectively doubles your gallons per minute,” Rountree says. “The air pumps shine when you’re filling large voids. You eliminate a lot of manual labor.”
A single diaphragm pump only needs three cubic feet of pressure, so operators can power it with a small, pancake compressor, making both the pump and the compressor portable. Another feature is the easy-to-use on-board controls.
