EPOXY GROUT SHOOTOUT 2.0 - FasTrac CE815 VS Escoweld 7505E/7530

Welcome to the Energy Tech Systems Epoxy Grout Shootout 2.0! Following the success of our previous Epoxy Grout Shootout, we're back to put two top contenders to the test once again.

In this case study, we examined FasTrac CE815 and Escoweld 7505E/7530, two of the most sought-after epoxy grouts on the market.

Our goal was to determine which product offers the best flowability, compressive strength, and cost-effectiveness for your machine grouting projects.

The Contenders: FasTrac CE815 and Escoweld 7505E/7530

FasTrac CE815 has already proven its mettle in our previous Epoxy Grout Shootout, emerging as the clear winner. To reference the details, check out our previous comparison here.

Escoweld 7505E/7530, on the other hand, entered the ring as a strong competitor known for its reliable performance and durability.

Testing Methodology

ASTM C1339 Flow box to test flowability and effective bearing area.

ASTM C579 Method B, Load Rate II

For 3- and 7-day compressive strength using plastic cube forms.

ASTM D2471 To measure peak exotherm.

The flow box test assessed the grouts' flowability by measuring the time it took for each sample to flow through a standardized 2-inch depth flow box. The faster the time, the higher the rate of flow.


We used the ASTM C579 Method B, Load Rate II Compressive Strength test to determine the compressive strength of each epoxy grout.


We also analyzed the ASTM D2471 Peak Exotherm Temperature to gauge the heat generated during the curing process. This data is crucial for applications that require precise temperature management.

Two samples of each epoxy grout were mixed according to each manufacturer's TDS at an average material & ambient temperature of 72 degrees Fahrenheit.

FasTrac CE815

  • 4-Bag (2.0 cf unit)

  • 5-Bag (2.4 cf unit)

Escoweld 7505E/7530

  • 4-Bag (2.0 cf unit)

  • 5-Bag (2.4 cf unit)

The flow box was set at a 2” depth and the epoxy grout mix was then poured into the flow box hopper. After waiting 3 minutes, the flow box gate was lifted, allowing the grout to flow through the trough. As soon as the grout contacted the backplate, the time was recorded. The faster the time, the higher the rate of flow.

Flow Box Results

The following chart shows the flow box times, peak exothermic temperature, and compressive strength.

The flow box results unveiled FasTrac CE815's impressive flowability. In the 4-bag category, it recorded the fastest flow time of 25.86 seconds, while the 5-bag achieved a swift 81.58 seconds.

Escoweld 7505E/7530, on the other hand, fell behind in each sample, with a 4-bag flow time of 42.75 seconds and a 5-bag flow time of 137.95 seconds.

Exotherm and Compressive Strength Results

The following video shows a side-by-side comparison of the flow box test in real-time.

ASTM D2471 Peak Exotherm Temperature

Both products displayed reliable peak exotherm temperature results, ensuring controlled curing processes without compromising structural integrity. The results were as follows:

FasTrac CE815:

  • 4-bag: 98.5 degrees Fahrenheit

  • 5-bag: 92.7 degrees Fahrenheit

Escoweld 7505E/7530:

  • 4-bag: 96.7 degrees Fahrenheit

  • 5-bag: 89.2 degrees Fahrenheit

Compressive Strength

The ASTM C579 Method B, Load Rate II Compressive Strength test showed that FasTrac CE815 outperformed Escoweld 7505E/7530 in this aspect as well.

FasTrac CE815:

  • 3-day compressive strength: 14582 psi

  • 7-day compressive strength: 14635 psi

Escoweld 7505E/7530:

  • 3-day compressive strength: 11785 psi

  • 7-day compressive strength: 13070 psi


Besides excelling in flowability and compressive strength, FasTrac CE815 stood out as the more cost-effective option, providing exceptional performance without breaking the bank.

Conclusion: FasTrac CE815 Triumphs!
