Civil infrastructure rehabilitation has become an exact science. In fact, the days of rehabilitating manholes, lift stations and wet wells with the same type of standard spray equipment and coatings is gone. Those jobs now demand precision application with application-specific coatings to help extend the life of the infrastructure. The sprayMASTER from Quadex, a Vortex company, is designed specifically for the rehabilitation of municipal manholes.

SprayMASTER is a completely self-contained manhole mortar lining installation system. It comes fully equipped for the precise, low-velocity spray and/or spin-cast application of cementitious and geopolymer mortar manhole lining materials. According to Sam Wisener, Quadex’s product manager, the unit is the company’s answer to the constantly evolving manhole rehabilitation industry.

“We designed sprayMASTER to be an all-in-one system that can utilize our GeoKrete, along with other lining systems,” he says. “We’ve found that as these lining systems have evolved, the methods with which they are applied have to adapt as well. This is a more efficient product.”

Key features of the sprayMASTER unit include a 250-gallon, poly-lined water tank, 44 hp Tier 4 turbo diesel engine with hydraulic power plant, a 29 cfm 90 psi air compressor, 20-gallon-capacity fuel cell, 40 psi hydraulically powered water transfer pump, Fill-Rite water metering system, an ergonomically positioned control center, 75-gallon-capacity mixer with vertical shaft mixing blade, three-stage progressive cavity material pump and holding hopper, a center-mount material platform designed to hold one pallet of Quadex lining material, and a compact-designed, low-velocity, wet mortar spray nozzle.

“We believe that utilizing a compact, all-in-one system can increase the efficiency of a rehab crew by 10% to 15%,” Wisener says. “We believe it’s important for crews to stay ahead of the game, and their competition.”

Wisener says much of the unit’s efficiency comes from a lining mixing system that is “twice as fast as previous models.” The unit can also be used in all climates, adding to its versatility. He says that beta tests of the unit in the field have been positive, and he expects to have units available for purchase in late summer.

“The feedback has been pretty overwhelming,” he says. “The contractors we have spoken with about this unit have indicated that having something like this is going to solve a huge need for them. We’re excited to see where it goes.” 855-949-3441;
