Integrity PowerPack Concrete Countertop Mix - 30 lb
About
Integrity PowerPack was developed to give concrete countertop professionals full control over their mix design without compromising performance. Unlike pre-blended mixes that lock you into fixed materials, PowerPack delivers the performance components separately, allowing you to select the cement and aggregates that best suit your application.
PowerPack contains the same dry curing polymer system, pozzolan blend, and defoaming technology used in Integrity PowerBlend. These components work together to increase strength, improve workability, reduce shrinkage, and create a denser, more durable concrete matrix. By removing the sand and Portland cement, PowerPack becomes a flexible mix design tool rather than a fixed formulation.
This flexibility allows professionals to use decorative or specialty sands, coarse aggregates, black sand, or alternative cements such as CSA cement. It also supports advanced concrete systems such as GFRC and ECC, where precise control over materials and performance characteristics is essential.
Integrity PowerPack is intended for experienced concrete countertop fabricators who want consistency, predictability, and control in their mixes. It provides the performance foundation needed to design concrete that meets both structural and aesthetic goals while adapting to the demands of each project.

HOW MANY SQUARE FEET DOES ONE BAG OF INTEGRITY POWERPACK MAKE?
Coverage depends on mix design and slab thickness. In a typical GFRC countertop mix using Integrity UltraFibers, sand, Portland cement, and a small amount of Integrity UltraFlow, one 30 lb bag of Integrity PowerPack yields up to 34 square feet at 3/4 inch thickness.
BENEFITS OF INTEGRITY POWERPACK
Following are the strength test results for PowerBlend. These strengths should be very similar for both PowerPack and PowerBlend. The values may vary for PowerPack because of the variety of sands and cement brands you might use.
At 0.30 w/c and 2.5% AR glass fibers:
| Compressive Tests | Flexural Tests | |
|---|---|---|
| 1 day | 6812 psi | 1339 psi |
| 7 days | 8706 psi | 1723 psi |
| 28 days | 11014 psi | 2188 psi |
- Contains the same dry curing polymer, pozzolan blend, and defoamer technology as Integrity PowerBlend, minus the sand and Portland cement
- Allows full control over cement and aggregate selection, enabling use of decorative sands, coarse aggregates, black sand, CSA cement, or other custom materials
- Greatly increases flexural and compressive strength when used in properly designed mixes, reaching high early strength for faster turnaround and confident demolding
- Produces denser, more durable concrete while helping reduce drying shrinkage, surface crazing, and curling
- Eliminates the need for a liquid polymer modifier, simplifying batching and reducing variability associated with liquid additives
- Suitable for the production of GFRC, ECC, UHPC-style mixes, SCC, hand-packed, and direct cast applications
- Contains a powerful defoamer that helps reduce pinholes and internal voids
- Eliminates the need for a 7-day wet cure when used in standard countertop applications
- Unaffected by freezing temperatures during shipping or storage
- More economical for large or remote projects by eliminating the need to ship sand and cement
Instructions
MIX DESIGN
If you are dosing pigments or various admixtures, you need to know the amount of cementitious material in your mix.
- Each bag of PowerPack contains 25.70 lb (11.657 kg) of cementitious material (pozzolans)
- We recommend adding 97.25 lb (44.114 kg) of Portland cement to each bag
- This results in a total cementitious material per bag of 122.95 lb (133.771 kg)
Below is a white concrete countertop mix recipe for GFRC using one bag of Integrity PowerPack.
| GFRC MIX RECIPE | |
|---|---|
| Integrity PowerPack | 30 lb |
| Sand | 122.95 lb |
| Portland Cement | 97.25 lb |
| Water (See notes on adding ice below) | (w/c = 0.30) – 36.88 lb |
| AR Glass Fibers 19 mm | (2.5%) – 7.36 lb |
| Integrity UltraFlow | Add a small amount of Integrity UltraFlow superplasticizer as needed for flowable mixes. One 1 lb jar will treat up to 530 lbs of SCC or direct cast concrete, or about 1.8 bags of PowerPack. |
| Total Cementitious Material | 122.95 lb |
| Coverage | Up to 34 sq ft at 3/4" thick, up to 25 sq ft at 1" thick |
MIXING INSTRUCTIONS FOR INTEGRITY POWERPACK
STEP 1
Dry blend together all of the sand, PowerPack, plus pigments and UltraFlow as needed. Concrete made with Integrity PowerPack is most effective when pre-blended into your sand before adding your mix water.
STEP 2
Add all the mix water plus ice to the sand + admixtures. Mix until all dry material is wetted out.
For flowable (SCC or direct cast) concrete, always chill your concrete using ice to achieve a concrete temperature of 55°F to 65°F. Chilling your concrete greatly increases working time and improves flowability.
Please use this chart to determine the amount of ice to use per full bag of Integrity PowerPack.
| Ambient Temperature | lbs of Ice | kg of Ice |
|---|---|---|
| 55°F / 13°C | 0 | 0 |
| 60°F / 15°C | 3.25 | 1.15 |
| 70°F / 20°C | 9.2 | 3.65 |
| 80°F / 25°C | 14.5 | 5.90 |
| 90°F / 30°C | 19.4 | 7.95 |
| 100°F / 35°C | 23.85 | 9.85 |
| 110°F / 40°C | 27.9 | 11.55 |
| NOTE: Ice replaces mix water by equal weight | ||
| It's assumed all mix ingredients, except ice, are at ambient temperature | ||
If your shop temperature is 90°F and you are using a half bag of PowerPack, replace half of the required ice amount. For example, if the full-bag chart calls for 19.40 lbs of ice, divide that in half:
19.40 ÷ 2 = 9.70 lbs of ice
Replace 9.70 lbs of your mix water with ice.
If your shop temperature is 85°F, calculate the required ice amount for both 80°F and 90°F, then use an amount approximately halfway between the two values.
The amount of ice does not need to be exact. The total combined weight of water and ice must remain exact.
Example:
If your mix design calls for 36.88 lbs of total water, and you determine that 14.50 lbs of ice is required:
You are replacing 14.50 lbs of water with ice.
Subtract the ice from the total water requirement:
36.88 − 14.50 = 22.38 lbs of liquid water
Your final batching amounts will be:
22.38 lbs of water
14.50 lbs of ice
The combined total equals the required 36.88 lbs of water.
STEP 3
Gradually add all the cement and blend until fully mixed.
- Add about 1/3 to 1/2 of the cement and blend until mix wets out.
- Add half of the remaining cement and blend further until mix wets out.
- Add remaining cement and blend until all dry ingredients are incorporated.
- Scrape the bucket and the mixing paddles well, then mix continuously on medium to high speed for no less than 2 full minutes. This is most important for flowable SCC/direct cast mixes.
- Make sure that any ice has fully melted before proceeding to the next step.
STEP 4
Add fibers last. Gradually add the fibers to prevent clumping and mix slowly to prevent whipping air into the mix. Ensure the fibers are fully wetted out and well dispersed throughout the mix. Do not mix on high speed.
