  • Application of hydraulic pressure through a pump to drive the wedges

When using this tool, always remember:

  • Use the right PPE (Personal Protective Equipment)
  • Ensure that you have a safe distance while applying the pressure
  • Strictly adhere to the manufacturer instructions

Cheers to another rock-breaking method at your disposal. The Hydraulic Splitting Technique offers its array of advantages and might be perfect for your next urban project. While its process is more intricate compared to expansive chemicals, it does the trick when you need precision, controlled rock splitting in urban areas. So don’t shy away from giving it a shot. Remember, the right tool for the right job has never been truer. Stay open, stay informed, and most importantly, stay safe.

Non-Explosive Demolition Agents

Before we dive in, let’s clarify what non-explosive demolition agents are. Essentially, they’re chemical compounds that safe the environment. They’re often used in conditions where traditional blasting isn’t feasible due to concerns about vibrations, noise, and safety.

Non-explosive demolition agents come in powder form. You’ll mix them with water before pouring the creamy substance into pre-drilled holes on the rock or concrete. Over a span of several hours, this compound expands, applying enormous pressure on the rock or concrete. This pressure causes the material to crack and split, ultimately leading to its disintegration.

The key to successful use of non-explosive demolition agents lies in:

  • Correct hole-drilling technique
  • Precise calculation of the quantity you’ll need
  • Adequate patience on your end.

In terms of the hole-drilling technique, you’ll specifically space and align the holes, in line with the compound supplier’s instructions. Accurate calculation of the quantity you’ll need permits the most effective use of the agent. And importantly, though it might sound trivial, patience is vital! Demolition agents aren’t the fastest solutions for rock breaking. The reaction time can range between 12 to 24 hours, even longer in cold conditions. However, you’ll find the slow pace is offset by the benefits of reduced noise, vibration, and safety risks.

Below, you’ll find a typical breakdown of the reaction times based on ambient temperature:

Ambient TemperatureReaction Time
20-25°C12-24 hours
10-20°C24-36 hours
0-10°Cup to 72 hours

The application of non-explosive demolition agents gives you a quieter, safer, more controlled rock breaking solution. By understanding the ins and outs of their usage, you’re adding another valuable tool to your construction arsenal. This method is particularly useful in sensitive areas where other methods, such as hydraulic splitting and traditional blasting, might not be suitable.
