Starting a concrete business or transitioning into this space calls for top-of-the-line training and equipment. It’s possible you want to work in this area, but are confused about where to start with choosing technology and polyurethane systems for projects. With HMI, you can select between PolyPro 20 and PolyPro 30. Your options for completing projects relating to sidewalks, driveways, seawalls and other concrete surfaces are made simple.
Understanding Polyurethane Concrete Lifting
The professionals at HMI map out some different factors you’ll need to remember for success when selecting our concrete lifting systems. Both PolyPro 20 and PolyPro 30 equipment packages are tailored to meet the needs of experts like you with diverse levels of experience.
A common misconception when considering equipment options is that a larger system is required to complete larger, heavier lifts. The system being used is nothing more than the equipment needed to heat, pressurize, mix and deliver the material. The system itself has no bearing on the lifting capabilities — this is determined by the foam installed.
Smaller, lighter slabs may use a quicker-reacting, lower-density foam. While large, heavy slabs may use a slower-reacting foam with a higher density.
PolyPro 20 vs. PolyPro 30 From HMI
PolyPro 20 and PolyPro 30 solutions from HMI share a similar name, but there are key differentiators worth noting before you can make an appropriate selection. The details below address both the similarities and differences of HMI’s technology and the situations in which you might prefer one offering over the other.
Similarities of PolyPro 20 and PolyPro 30
Our PolyPro 20 and PolyPro 30 systems work with our full catalog of foams. Whether you are working in residential neighborhoods for development projects or you need to service concrete surfaces in a commercial business park, you can stay ready for anything ahead.
The PolyPro 20 and PolyPro 30 are self-contained systems designed for raising concrete. They both install the same material using the same patented EliteONE injection gun and can complete the same types of projects. However, depending on which product you choose, your options for working on projects of a certain scale change drastically.
Differences Between PolyPro 20 and PolyPro 30
When comparing these two systems, consider volume capabilities, hose reach, equipment involved, the associated vehicle options and price point.
The main difference between these two systems is the volume of material they can install. The PolyPro 20 uses a 20-pound-per-minute proportioner, while the PolyPro 30 uses a 30-pound-per-minute proportioner. This means the PolyPro 30 can install 10 pounds per minute more than the PolyPro 20.
This may sound like a small difference, but users will notice a significant change in output, especially with large-scale projects that involve raising multiple concrete slabs, such as on a college campus or in a public park or healthcare facility.
Picture an interstate roadway needing multiple miles of slabs raised and joints stabilized. This can require hundreds of thousands of pounds of polyurethane. Now, imagine being able to install that quantity of material at a rate of 10 pounds per minute more. This can eliminate hours of work, saving you time and money on labor.
Equipment Capabilities and Vehicle Compatibility Options
Another factor to consider is the reach of the heated hose in the system. The PolyPro 20 system can pump through a maximum of 210 feet of hose, and the PolyPro 30 can pump through up to 310 feet of hose.
HMI recommends the 210-foot capability option for residential projects. However, if you want to expand your options or complete multiple concrete lifting jobs more quickly, the extra 100 feet of hose may aid your efficiency. We find that the PolyPro 30 is beneficial for more unique residential jobs, like repairing deeply sunken pool decks.
You may be asking yourself, “Why wouldn’t I just go with the PolyPro 30 system that can pump more pounds of material per minute and reach farther?” Well, there are a few more factors to consider.
Reactor Sizes
The PolyPro 30 uses a larger reactor than the PolyPro 20 system, which requires a larger diesel generator to power in comparison to the smaller gas generator in the PolyPro 20 system.
These larger components require more available space and a higher payload capacity in the vehicle. Because of this, the PolyPro 30 system requires a larger 16-foot trailer with larger axles or to be installed into an ample-sized box truck. This eliminates the possibility of operating out of a van, such as a Ford Transit or Mercedes Sprinter.
The PolyPro 20 system can be installed into a 14-foot trailer with a lower axle rating, a box truck or a van. This gives you more options when considering the market you’ll be working in. If working in a high-traffic city, operating out of a trailer can be difficult. The larger footprint of the trailer/truck combination can make it more difficult to maneuver and find parking. In these market types, the ability to operate out of a van can be priceless due to the convenience it provides.
Price Points
The last factor to consider is the difference in price point of the equipment when starting a new concrete raising business or adding the service to an existing company. As previously mentioned, the PolyPro 30 system has a larger reactor, diesel generator, and requires a larger vehicle to operate out of.
All of these factors drive the equipment cost above that of the PolyPro 20 system. Also mentioned earlier is that these systems can perform the same work. Therefore, does the larger investment of the PolyPro 30 system make sense if you’re focusing on the residential market, or do you feel that the PolyPro 20 system may limit you if your future goals include entering the commercial and/or DOT markets?
