Topking (Expandag) Expansive Mortar, also widely known as Stone Cracking Powder or Rock Breaking Chemical, is the industry-leading substitute for explosives. Renowned for being noiseless, vibration-free, and safe, it acts as a powerful Chemical Stone Splitter for granite quarrying and concrete demolition. We customize our mortar according to your local temperature, offering excellent factory prices and unparalleled quality.
● Unmatched Efficiency: Achieve controlled cracking within 8-24 hours. Generates 120 MPa expansive pressure from within.
● Precision and Control: Unlike explosives, the cracking is predictable. Break rock and concrete to your exact pattern.
● Absolute Safety (No Vibration): A completely non-explosive demolition agent. No fly-rocks, no license needed.
● Eco-Friendly: Produces no noise, dust, or pollution. Ideal for urban restricted areas.
Expansive Mortar, also known as Static Breaking Agent, generates huge internal volume expansion when mixed with water. It produces a uniform pressure of 100 to 123 MPa (14,500 - 17,800 PSI) inside pre-drilled holes, breaking hard rocks and reinforced concrete from within.
To achieve the best cracking results, drilling accurate holes (38mm-40mm) is critical.
We highly recommend using Topking
Hand Held Rock Drills
paired with our durable
Tapered Drill Rods
and
38mm Drill Bits.
*Correct drilling ensures the chemical reaction starts successfully without blowout risks.

Rock pre-splitting, fracture, and removal.
Controlled Concrete Demolition when explosives are prohibited.
Demolition of concrete buildings, pillars, and beams.
Rock cutting for road construction and tunneling.
To ensure optimal cracking, select the model based on the local ambient temperature:
| Model Type | Temperature Range | Best Application |
|---|---|---|
| HSCA-1 (High Temp) | 25°C to 35°C | Hot Summer / Middle East / India |
| HSCA-2 (Standard) | 10°C to 25°C | Spring / Autumn |
| HSCA-3 (Cool) | 5°C to 15°C | Cool Weather |
| HSCA-4 (Winter) | -5°C to 5°C | Cold Winter / North America |

Q: How much stone cracking powder do I need?
A: It depends on hole diameter. Typically 15-20kg per m³. Contact us for a precise calculation.
Q: Can it break reinforced concrete?
A: Yes! It serves as an excellent Concrete Demolition Powder, cracking concrete to separate rebar easily.
Q: Is it safe?
A: Absolutely. Non-explosive and silent. Always wear safety goggles and gloves.
