Expansive Mortar (also known as Soundless Cracking Agent) is the safest and most legal-friendly alternative to explosives for rock demolition in 2025. Unlike controlled blasting, which requires strict licenses and causes ground vibration, expansive mortar generates 120 MPa of expansive pressure to crack rock silently.
To help project managers make the right choice, we compared Topking Expansive Mortar with traditional dynamite blasting:
| Feature | Topking Expansive Mortar | Traditional Explosives |
|---|---|---|
| Safety | 100% Safe (No vibration, No fly rock) | High Risk |
| License | No License Needed | Strict Permit Required |
| Noise | Silent Operation | >120 dB (Loud) |
| Cost Efficiency | Lower overall cost for urban projects | High security & labor cost |
Based on Topking's laboratory data, choosing the right type for your local temperature is crucial.
Pro Tip: Perfect cracking starts with the perfect hole. We highly recommend using Topking Rock Drills, paired with our durable Tapered Drill Rods and 38mm-40mm Drill Bits to ensure efficient drilling and standard hole sizes.
HSCA-1 (High Temp): For 25°C to 40°C
HSCA-2 (Medium Temp): For 10°C to 25°C
HSCA-3 (Low Temp): For -5°C to 10°C
Q: How much expansive mortar do I need per m³?
A: Generally, the consumption is about 15kg to 20kg per m³. For a precise calculation based on your drilling design, please contact Topking engineering team.
Q: Can it break reinforced concrete?
A: Yes! It effectively cracks the concrete, separating it from the rebar (steel bars), making demolition safe and easy.
