GCX Concrete Grinder
Propane. Planetary. Productive
40 percent faster at start up to first 5,000 square feet.
The GCX is designed to work quickly. Roll it off the trailer and begin grinding immediately – thanks to clean burning, quick drop-in propane power. All steel frame construction with a 27 hp engine ensure you have not only the weight and head pressure for coating removal and concrete profiling, but also the speed and RPMs for efficient wet honing and polishing. On board sensors provide hours and RPMs and safety features including automatic emissions sensor with shutdown. An 11-gallon water tank will eliminate any airborne silica dust as will the built-in vacuum port. Quick change plates promote even abrasive wear and quick field changes cutting downtime on every PHP (Profile. Hone. Polish.) project.
Concrete Grinding Equipment
The Green Umbrella GCX Grinder is the next step for the industry’s oldest and most most reliable propane powered, planetary concrete grinder. Durable, self-contained gear box powered by a 27hp EPA/CARB certified engine.
The GCX Grinder can tackle any element of concrete surface refinement from coating removal to high rpm polishing. A flexible frame enables this machine to follow the contour of any concrete surface regardless of Ff or Fl numbers on new or existing concrete.
Equipped with a standard quick change system to promote even abrasive wear and quick field changes cutting downtime on PHP projects.
Cut Your Labor
Cut concrete in any phase – Profile, Hone or Polish – from 600 – 1,600 sq.ft. per hour.
Cut Your Downtime
Propane power enables you to be working in any phase of construction without reliance on electrical power.
Cut Your Environmental Impact
Clean & renewable propane fuel source. Designed for wet cutting to eliminate hazardous silica dust.

Cut the Cord!
Propane fuels the New 27 hp engine that is certified to meet EPA and CARB requirements with an ESDS (Emissions Shut Down System) and clean burning catalytic muffler.
Propane tanks drop in for quick and easy changes. A sturdy, mining industry inspired GreenGEAR™ gearbox will enable you to have a truly industrial piece of equipment exceeding the run time of any other grinder on the market, by THOUSANDS of hours. The Green Umbrella GCX Grinder is a responsible alternative for professionals concerned about the environmental impact of the concrete polishing process. Producing benefits seen immediately onsite by using propane and cutting wet.
Propane power eliminates the potential hazard of water meeting electricity. The wet process uses water to cool diamond abrasives and eliminate dust. Water reduces abrasive friction and acts as a lubricant, thereby increasing the life of grinding and polishing abrasives.
Water + 500 lbs Head Pressure + Cutting Edge = Refinement
Additional Feature: The GCX Grinder is designed specifically for wet grinding and is outfitted with an 11- gallon water tank. Equipped with a standard quick change system to promote even abrasive wear and quick field changes cutting downtime on PHP projects.
The wet process eliminates airborne crystalline silica dust and its potential health hazards such as silicosis due to the inhalation of these dangerous airborne particulates improving IAQ (Indoor Air Quality). Propane is one of the cleanest burning fossil fuels, cutting emissions and leaving a smaller carbon footprint than a typical electric model.
The Hidden Issues Abrasive Cutting with Electric Equipment
Hurry Up and Wait! Electric powered machines generally require 3-phase power wired by a certified electrician and drawing considerable power from the facility. Green Umbrella recommends the use of renewable resources such as propane powered, clean-burning EPA & CARB certified engines.
Hidden Cost to Ownership: Calling upon the facility maintenance team and requesting an electrician establish suitable power is just the start. Each electric machine will draw substantial kilowatts of energy during the course of the project.
Sample Electric Grinder Motor (40 Amps – 460 Volts) – 31.8 kilowatts x $0.12 cents per kwh = $3.82 per unit per hour. Average daily operating cost (8 hour day) – $30.53 per machine paid by facility ownership daily.
Sample Project: 5 day project using 2 electric machines will total $305.30 in “hidden cost” to ownership.
Equipment that is NOT Designed to Cut Wet: While Green Umbrella’s fleet of grinders are designed to cut wet, Electric Grinders are not. Water + Electricity do not mix! Eliminate danger and protect workers all without possibly introducing harmful silica dust into the air – by using equipment designed for wet profile, hone and polish work. Propane or Diesel powered machines eliminate the potential hazard of water meeting electricity.
Expensive Portable Generators and Cords: Not required when using Green Umbrella grinders. Construction sites are filled with potential hazards. Eliminate the potential for a trip and fall by eliminating the use of cords while profiling, honing and grinding – choose cordless propane equipment.
