Our Expanding Grout’s Standard Performance: Best In Class

If you haven’t already heard about our latest and greatest expanding grout product – let me introduce you to Rock X, our premium brand expanding grout, renowned for its strength, reliability, and user-friendliness. Mixing one bag of expanding grout with 1.5 liters of water and pouring it into holes ranging from one to two inches in diameter and up to 20 feet deep is all it takes. Hole spacing can vary from one to two feet, depending on the rock’s hardness. For a free quote, simply click the link and provide us with a few pictures and dimensions of the target area.

Elevating Our Grout Performance: Making the Best Even Better

To enhance your grouting experience, we recommend utilizing our accessories. Our hole plugs effectively keep dirt and debris out, maintaining clean and ready-to-pour holes. If you encounter water or cracks in the holes, our plastic sleeve liners offer a solution, ensuring the grout stays inside.

Choosing the appropriate temperature type is important. Type 3 suits temperatures from minus 5 to 10 degrees Celsius, while Type 2 is ideal for 10 to 25 degrees Celsius. Type 1 covers 25 to 40 degrees Celsius, and Type 0, our extreme heat option, is for 40 to 50 degrees Celsius. Selecting the right temperature range is essential to prevent overheating or dormancy of the grout.

Using Your Grout-Additive Mixture: How It Works

Upon mixing, the grout transforms into a liquid form, similar to a cement slurry. Once poured in the holes, it heats up, forming a paste that eventually solidifies. The chemical reaction within the product generates heat, emphasizing the importance of the correct temperature range, primarily determined by the rock temperature.

Using Expanding Grout Like A Pro: How To Adapt To Temperatures

If temperatures exceed the chosen range, overheating may occur, leading to a potentially hazardous blowout. Conversely, colder temperatures can render the grout ineffective, causing dormancy until warmer conditions arise. To maintain consistent productivity, consider covering the grout with a tarp and applying minimal heat during cooler nights.

Adjusting the water quantity can affect the grout’s reaction time. More water slows it down, providing ample time for pouring, while less water accelerates the process, hastening rock breaking.

The principles of using expanding grout mirror those of blasting. A relief or open face is necessary for effective rock breaking. Patterns for drilling vary based on intended outcomes, whether reducing rock to rubble or splitting it into segments.

Estimating the required grout quantity is simple using our formula or calculator. Once determined, shipping can be arranged promptly, usually within 12 to 24 hours.

While cracks may begin to appear within six to 12 hours, the grout continues to exert pressure, producing more cracks over two weeks or more, provided optimal conditions of temperature and dryness are maintained.
