Large-Hole Expansive Demolition Grout
Brighttop Global Co., Ltd. supplies large-hole expansive demolition grout developed for controlled, non-explosive cracking of rock and concrete. It is suitable for large-diameter drill holes ranging from 70 mm to 140 mm and is designed to create effective cracking within approximately 12–48 hours under suitable working conditions.
The expansive grout can be used for quarrying, mining, boulder splitting, foundation removal and reinforced concrete demolition. It provides an alternative solution for projects where conventional blasting is restricted because of vibration, noise, flying debris or nearby buildings.
After being mixed with the required amount of clean water and poured into prepared drill holes, the grout gradually generates expansive pressure inside the material. This controlled pressure creates cracks without using explosives, making it particularly suitable for large-scale rock and concrete splitting applications.
Key Features and Advantages
| Feature | Description |
|---|---|
| Large Drill Hole Compatibility | Designed for drill hole diameters from 70 mm to 140 mm, making it suitable for large-scale rock and concrete splitting applications. |
| Controlled Cracking | Produces gradual expansive pressure inside the drilled material, helping operators control the direction and location of cracking. |
| Non-Explosive Demolition | Provides a practical alternative for projects where blasting permits, vibration controls or safety restrictions limit the use of explosives. |
| 12–48 Hour Cracking Time | The material is designed to develop visible cracking within approximately 12–48 hours, depending on ambient temperature, material hardness, hole depth, spacing and operating conditions. |
| Wide Application Range | Suitable for natural rock, quarry blocks, concrete foundations, reinforced concrete structures, large boulders and civil engineering demolition. |
| Customizable Packaging | Packaging and OEM service available according to order requirements and project specifications. |

Frequently Asked Questions
What drill hole diameter is recommended?
The recommended drill hole diameter is 70–140 mm, depending on the material, project design and required cracking result.
How long does the grout take to crack rock or concrete?
The typical cracking time is approximately 12–48 hours under suitable operating conditions. Temperature, material hardness, drill hole depth and hole spacing can affect the actual cracking time.
Is large-hole demolition grout explosive?
No. It is a non-explosive expansive cracking material that develops gradual pressure inside drilled holes.
What materials can it break?
It can be used for natural rock, quarry stone, large boulders, concrete foundations and reinforced concrete structures.
Where can this product be used?
It is commonly used in quarrying, mining, construction, civil engineering, foundation removal and controlled demolition projects.
Safety Notice
Important: The powder and freshly mixed slurry are strongly alkaline. Operators must wear suitable gloves, eye protection, protective clothing and respiratory protection during mixing and filling. Do not look directly into filled boreholes, do not cap the holes, and keep personnel away during the reaction period. Store unopened bags in a dry warehouse on pallets and protect from moisture. Product use must follow the supplier's technical data sheet, safety data sheet and local regulations.
