Rock - XX is built for commercial demolition project where you need to demolish large concrete structures, bedrock and massive bolders. We engineered this grout to require less man hours, and to require less drill holes.

• Neglecting Comprehensive Reading: A common oversight is failing to thoroughly read and digest the User Guide, instructions, and FAQs provided.

• Inappropriate Grout Selection: Another prevalent mistake is selecting the wrong type of grout for the job at hand.

• Ignoring Expansion Requirements: Overlooking the necessity of providing adequate expansion space for the concrete or rock to fracture and disintegrate when using grout.

• Incorrect Hole Dimensions: Using holes with the wrong diameter or spacing them too far apart can lead to ineffective results.

• Shallow Material Depth: Insufficient material depth can hinder the breaking process.

• Impatience: Rushing the process by not allowing the grout a full 24-48 hours to achieve maximum expansion and facilitate wider cracking.

The answer is straightforward: a thoughtfully crafted hole-drilling pattern brings about a range of significant advantages:

• Enhanced Grout Efficiency: A well-designed pattern maximizes the efficiency of your grout, ensuring it achieves the desired results.

• Cost Savings: By optimizing the pattern, you'll minimize grout consumption, leading to financial savings.

• Precision and Control: A carefully planned pattern enables precise and controlled breaking, minimizing the potential for unexpected outcomes.

• First-Time Success: With a strategic drill pattern, you increase the likelihood of completing the job correctly on the initial attempt.

• Structural Safeguard: Thoughtful planning helps protect any nearby sensitive structures from unintended damage.

To achieve optimal results with grout, it's imperative to provide the material with an unobstructed surface or adequate room for expansion and subsequent fragmentation. Attempting to break rock or concrete that is completely enclosed on all sides inhibits the expansive pressure generated by the grout from effectively causing the material to crack and fracture.

Spacing, depth, and drill pattern should be adjusted based on:

• Project objectives

• Material density

• Presence of reinforcing

• Desired size of broken material

• Desired cracking time

• If you need to protect an adjoining structure

Drilling holes and intentionally leaving them unfilled can serve a multitude of strategic purposes, including:

• Facilitating Controlled Expansion: Unfilled holes provide vital expansion space for the material to fracture when it's enclosed or confined.

• Precision Cracking: These empty holes enable precise control over the cracking process, ensuring it follows the desired path.

• Grout Conservation: By strategically leaving some holes unfilled, you can reduce the overall amount of grout required for the operation.

• Accelerated Breaking: Empty holes can expedite the breaking process, helping you achieve your goals more quickly.

• Structural Protection: When necessary, unfilled holes allow for controlled breaking to protect specific parts of a structure.

• Fracture Guidance: These empty holes can direct the fracturing in a way that aligns with your project's requirements.

• Corner Creation: In applications such as forming openings or stone quarrying, unfilled holes play a pivotal role in shaping corners as needed.

More holes spaced closer together results in:

• Faster break times

• Smaller and more manageable pieces

• Adds labour cost (drilling & filling more holes)

• May increase quantity of grout used

• Reduces the cost of rubble removal

For best results with ROCK-X, we highly recommend 1” diameter holes - do not exceed 2.5”.

For best results with ROCK-XX, we highly recommend 2.5” diameter holes - do not exceed 5”. Using smaller diameter holes will require holes to be spaced closer together and may NOT be successful in some materials.

No. For grout to be effective, we strongly recommend materials to be cracked be a MINIMUM of 3” in depth.

The best time to pour grout is early in the morning. An effective strategy is to drill holes the day prior, so you can pour first thing early the next morning. In cold conditions, add a tarp and a heater overnight.

• Using the wrong grout type
• Pouring grout mixture into warm/hot holes
• Using warm water. In hot conditions, use cold or ice water
• Hole diameter is too large and too deep
• Adding grout and water to leftover mixture remaining from previously mixed batch
• Not measuring water or using too little water
• Too much time passing between beginning to mix and pouring into holes
