Workflow for BETONAMIT® Standard (liquid)
For Vertical and Downward-Directed Boreholes
- First, drill holes with a diameter of 30-40 mm. The optimal distance between the holes is ten times the diameter, approximately 30-40 cm. The holes should be as clean and dry as possible.
- Pour the BETONAMIT® powder into the mixing container. Then add 1.0 to a maximum of 1.2 liters of cold, clean water per 5 kilograms of powder. Mix the components with an electric mixer until a flowable, homogeneous mixture is formed.
- Pour the mixture directly from the mixing container into the drilled holes.
- The entire processing time should not exceed 5 minutes.
- No additional mechanical sealing is required.
- For special applications of BETONAMIT® with hole diameters over 40 mm, prior consultation with the manufacturer is mandatory.
Positioning of Boreholes
Crack formation always follows the path of least resistance. A larger borehole diameter results in more force, shorter reaction time, and wider crack formation. Closer borehole spacing produces smaller fragments and leads to a faster reaction.
The holes are drilled in a line with a small distance between them. This causes the cracks to form from hole to hole. In this way, objects can be relatively precisely cut or split during blasting operations.
To achieve the smallest possible fragments, the holes are drilled in multiple staggered rows. As the number of boreholes increases, the resulting fragments become smaller. The cracks form crisscross through the material.
There are various techniques for rock excavation or demolition. The drilling pattern is chosen according to the shape and nature of the rock or adapted to local regulations. The principle remains the same: first, an open side, i.e., a straight edge, is created. From this edge, the excavation can then be continued as needed.
We understand that every project is unique and comes with its own individual challenges. That’s why we want to ensure that you always receive the best possible support when using BETONAMIT®. If you have any questions or would like to present your specific demolition project to us, please do not hesitate to contact us. You can send us photos and a description of your project at any time. Our experienced team is happy to provide you with customized solutions and support you on your way to a successful project completion.
If there is no free space for the displacement of the material, space must first be created. This can be done either by opposite boreholes at an angle of 50-60° or on one side at an angle of 40-50°. Angled boreholes are also suitable for creating a large-scale lowering of the ground level, for example, when working in basement rooms.
For rock excavation, the holes are drilled in multiple rows 10-15 cm below the required ground level and filled. This breaks and loosens the ground, allowing it to be removed with an excavator or partially by hand. Here too, the expansive agent works most effectively when the holes are drilled at a slight angle, so that part of the force acts upwards.
The use of BETONAMIT® in quarries and similar applications is becoming increasingly important. The regulations for the use and storage of explosive materials are difficult to comply with in many countries, leading to a growing search for alternatives. The optimal application in these areas depends greatly on the local situation and the material to be blasted. We are happy to work with you to develop a concept tailored to your needs (e.g., marble extraction, granite extraction, etc.).
Berechnung des Materialverbrauchs
The material consumption is calculated from the sum of the depths of all boreholes multiplied by the corresponding factor (according to the table) of the used borehole diameter.
In the table, you will find the factors in the most common weight and length units used in the construction industry, as well as in combination.
Example Calculation:
You have 15 boreholes with a diameter of 35 mm and a depth of 0.60 meters. The factor = 1.6 kg. Calculate 15 x 0.60 meters x 1.6 kg = 14.4 kg BETONAMIT®.
Technical Specifications
The following table shows the expected reaction time depending on the temperature. Additionally, you will find further helpful information for the application. Since the borehole diameter significantly affects the expansion force and reaction time, we recommend choosing the largest possible drill bit whenever feasible.

BETONAMIT® continues to expand over several days. This means that the more time you allow BETONAMIT® to work, the easier it will be to remove the resulting fragments. So, be patient and let BETONAMIT® do the hard work for you.
