• Brand: EXPANDAG / TOPKING

• Type: HSCA-4 (Ultra-Cold Winter Type)

• Temperature Range: -10°C to 5°C (14°F - 41°F)

• Package: 20kg/carton (5kg x 4 vacuum bags)

• Application: Specialized for winter mining and concrete demolition in freezing climates (Russia, Canada, North Europe).

HSCA-4 (Winter Type) is a hyper-reactive soundless cracking agent engineered as part of our Expansive Mortar Powder series. While standard mortars stop working below 10°C, HSCA-4 ensures your rock breaking projects continue year-round, even in the harshest North American and European winters.

HSCA-4 Technical Specifications

❄️ Critical Tips for Freezing Weather:

To ensure HSCA-4 reaches peak 120MPa pressure in cold air, follow these rules:

• Use Warm Water: Mix with water between 20°C - 30°C to kickstart the chemical reaction.

• Insulation: Cover filled holes with plastic tarps or mats to retain internal reaction heat.

• Matched Tools: Use Topking Rock Drills and 38mm-40mm bits for standard borehole patterns.

Why Choose Expandag HSCA-4?

• Zero Project Delays: Continue mining and demolition work throughout the winter season.

• Safe & Predictable: Avoids the unpredictability of explosives in extreme cold.

• Global Supply: Trusted by contractors in Moscow, Toronto, and Stockholm.

Cold Weather Stone Cracking & Winter Expansive Mortar FAQ

Q: What happens if I use HSCA-4 in summer?

A: DANGER! Never use the winter version in temperatures above 10°C. HSCA-4 is extremely reactive and will cause an immediate, dangerous blowout in warm weather. Always match the version to the ambient temperature.

Q: Does it work on frozen concrete building foundations?

A: Yes. HSCA-4 is highly effective for breaking reinforced concrete even when the structure is at sub-zero temperatures, provided the mixing and insulation guidelines are followed.

Q: How do you ship to cold regions like Canada or Russia?

A: We use heavy-duty moisture-proof packaging to ensure the powder stays dry during long-distance transit to cold regions, ensuring the chemical integrity of the product upon arrival.

Q: What is the correct water-to-powder ratio for winter expansive mortar?

A: For HSCA-4, the recommended ratio is 1.5 to 1.7 liters of warm water for every 5kg bag of powder. Ensure the mixture is stirred into a smooth, lump-free slurry before pouring.

Q: How much winter stone cracking powder is needed per m3 of rock?

A: Generally, you will need 12kg to 20kg per cubic meter (m³) of rock. This varies based on the hole diameter and rock hardness; harder rocks like granite in winter may require tighter hole spacing.

Q: How long does HSCA-4 take to crack rock in sub-zero temperatures?

A: While standard agents fail in the cold, HSCA-4 starts showing visible cracks within 12 to 24 hours. Using warm water (30°C) and covering holes with thermal blankets can accelerate this process.

Q: What is the recommended hole pattern for winter rock breaking?

A: We recommend a hole diameter of 38mm-45mm with a spacing of 30cm to 50cm. For reinforced concrete demolition in winter, reduce the spacing to 20cm-30cm for better rebar separation.

Q: What safety precautions are required when using HSCA-4?

A: Operators must wear safety goggles, rubber gloves, and a dust mask. Because winter formulas are highly reactive, never look directly into filled holes to avoid injury from accidental blowouts.

Q: Is the winter soundless cracking agent safe for environmentally sensitive sites?

A: Yes. It is a non-toxic, eco-friendly chemical. It produces zero vibration, noise, or dust, making it ideal for winter projects near protected waterways, pipelines, or urban residential areas.
