Example: Removing a concrete block in the garden
In this example, we will show you how to remove a 1 x 1 meter concrete foundation in your garden. The foundation extends 35 cm above the ground and needs to be broken off at ground level, leaving the 50 cm portion in the soil untouched. To achieve this, we will drill holes with a depth of 40 cm (never drill completely through). This allows us to break the upper part of the foundation below the surface and later cover it with some soil.
Procedure:
- Prepare drill holes: Drill a total of 9 holes (three rows of three drillings) with a diameter of 30 mm and a spacing of 30 cm. Ensure the drill holes are clean and dry.
- Mix BETONAMIT®: Pour the BETONAMIT® powder into a mixing container. Add 1.2 liters of clean, cold water per 5 kg of powder (if you need less, measure and weigh it precisely beforehand). Mix everything with a stirrer until a flowable, homogeneous mixture is formed.
- Fill drill holes: Pour the mixture directly from the bucket into the drill holes. Make sure the total working time does not exceed 5 minutes. No additional mechanical sealing is required.
- Wait for the reaction time: After a few hours, BETONAMIT® will develop a strong expansion pressure that breaks the concrete foundation. You will then just need to remove the remaining concrete pieces.
