How Do You Use Expanding Grout?
Learning how to use expanding grout is a simple process that involves a few important steps below:
Drill the Holes
Start by drilling evenly spaced holes into the rock or concrete you want to break. The depth and spacing depend on the material and the type of expanding grout used. Using a handheld drill? ROCK-X is the product for your project! Using a big-rig-drill? ROCK-XL is the grout for your job!
Calculate the Grout Needed
Measure the total volume of the drilled holes to determine how much grout you’ll need.
Mix the Grout
Combine the expanding grout powder with the recommended amount of water, stirring until you get a smooth, lump-free consistency.
Pour the Grout
Carefully pour or funnel the mixture into the drilled holes, filling them up to about 90-95% to allow for expansion.
Wait for Expansion
Over the next few hours (or up to 24 hours, depending on the grout type and temperature), the grout will expand, creating immense pressure that causes the material to crack and break apart.
Remove the Debris
Once the cracks have fully formed, you can easily remove the broken pieces with minimal effort—no explosives, jackhammers, or heavy vibrations needed!
How Do You Choose Between ROCK-X and XL?
Not sure which product is right for your job? Here’s a quick guide:
ROCK-X
ROCK-X is designed for standard drill holes—perfect for holes drilled by hand or with smaller equipment. It works best in 1-2″ deep holes and is ideal for tight spaces or lighter-duty breaking jobs.
ROCK-XL
XL is made for larger holes, typically those made with a big rig drill 3″ deep holes +. If you’re working on heavy-duty demolition or need more expansive breakage power, XL delivers the strength required for those larger applications.

How Does Expanding Grout Work?
Expanding grout is a game-changer in the demolition world, offering a non-explosive method to fracture rock and concrete. When mixed with water and poured into pre-drilled holes, this compound undergoes a controlled expansion, exerting immense pressure on the surrounding material.
This force causes the rock or concrete to crack and break apart without the noise, vibration, or flying debris associated with traditional blasting methods. It’s a silent powerhouse, making it ideal for projects in sensitive environments or urban areas where minimizing disruption is crucial.
Top Benefits of Expanding Grout
Reduce safety risk
Explosives and heavy rock breaking equipment pose safety concerns for people, property and the environment around the job site. When you choose expanding grout the risks of noise, vibrations, fly-rock and expansion gases are eliminated!
Environmentally friendly
All our expanding grouts pose no risk to the environment. They release no toxic fumes, leave no residue and easily wash away with water. They are safe to use, even in environmentally sensitive areas and have been endorsed by environmental consulting firms.
Cost effective
Our products ensure you can get your rock-breaking done at a fraction of the cost of the alternatives. Whether you’re considering explosives, heavy equipment rentals or jackhammers, the value of expanding grout cannot be beaten.
Easy to use
Expanding grouts don’t require any permits or specialized training to be used! Anyone can be properly trained to use expanding grouts in a matter of minutes and ROCK-X & ROCK-XL can be bought over the counter. As easy as 1, 2, 3! Drill your holes, mix the slurry, pour it in and let it work its magic! Our hassle-free expanding grouts give you peace of mind that your breaking job can be done easily and efficiently.

Expanding Grout FAQ
What is expanding grout, and how does it work?
Expanding grout is a non-explosive demolition agent that, when mixed with water and poured into drilled holes, expands over time to break apart rock or concrete with immense pressure.
How does expanding grout compare to traditional blasting methods?
Unlike blasting, expanding grout works silently, without vibrations, dust, or flying debris, making it a safer and more controlled demolition method.
Is expanding grout safe to use?
Yes, when used correctly. It is non-toxic, non-explosive, and does not produce harmful fumes, though safety precautions like wearing gloves and eye protection are recommended.
What materials can expanding grout break apart?
It works on rock, concrete, reinforced concrete, granite, limestone, and other hard materials that require controlled breaking.
Does expanding grout work in the rain?
Yes it does! We still recommend covering the holes after filling them with grout to keep the elements from affecting the efficacy of the expanding grout. We do recommend not using the product if it is submerged in water.
