Topking (Expandag) Expansive Mortar is the industry-leading substitute for explosives. Renowned for being noiseless, vibration-free, and safe, it has shown immense potential in 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. The powerful expansive force works from within, speeding up project timelines compared to jackhammers.
● Precision and Control: Unlike explosives, the cracking is predictable. Break rock and concrete to your exact pattern without damaging surrounding structures.
● Absolute Safety (No Vibration): A completely non-explosive solution. No fly-rocks, no harmful fumes, no loud noises. No special permits or safety zones needed.
● Eco-Friendly: Produces no noise, dust, or pollution. Ideal for sensitive, urban, or 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.
Granite, marble, sandstone, and limestone Quarrying & Block Cutting.
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.
Excavation of trenches and foundations.
To ensure optimal cracking, select the model based on the local ambient temperature:
| HSCA-1 | 25°C to 35°C (Hot Weather) |
| HSCA-2 | 10°C to 25°C (Standard) |
| HSCA-3 | 5°C to 15°C (Cool) |
| HSCA-4 | -5°C to 5°C (Winter) |
Packaging: 5kg (11 lb.) x 4 bags per carton. Total net weight 20kg (44 lb.). Wrapped in anti-moisture plastic.
Storage Guidelines:
Store in a dry warehouse on pallets. Do not place directly on the floor.
Shelf life: Approx. 1 year if stored correctly.
Use immediately after opening the bag. Do not use powder from broken bags.
Q: How much expansive mortar do I need?
A: It depends on hole diameter and spacing. Typically 15-20kg per m³. Contact us for a precise calculation.
Q: Can it break reinforced concrete?
A: Yes! It is powerful enough to crack heavily reinforced concrete, making rebar removal easy.
Q: Is it safe?
A: Absolutely. Non-explosive and silent. Always wear safety goggles and gloves during mixing.
