Application examples

Concrete demolition

The areas of application for Betonamit® for concrete demolition are practically unlimited. It is possible to determine from the outset what the size of the pieces should be, as well as which direction the cracks should run in, through the number and positioning of the drill holes. In this illustration, for example, 5 holes have been drilled and approximately 8 kg of non-explosive demolition agent is used.

Blasting rocky underground

During excavation expansion for a detached house, the construction company encountered rocky underground. The use of a demolition hammer or explosive blasting agents was not possible resp. prohibited. The underground was first broken up with BETONAMIT and could then removed with a shovel.

Minimisation of vibration transfers during blasting operations

Due to high vibration levels an explosive detonation was initially prohibited. After a pre-splitting of the vibration transferring rock layer, the subsequent excavation was then blasted in the conventional way. On the image you can see the exact breaking edge.

Fragmentation of large rocks or boulders

This image illustrates very well how large rocks can be fragmented with Betonamit. The degree of fragmentation is freely selectable and dependant on the number, depth and positioning of the placed boreholes.

Removal of rock outcroppings

In this example some rock outcroppings were in the way of further concreting work. They were drilled at about 10cm below the required floor level and filled with Betonamit. The next morning the fragments could be quickly and easily transported away

Horizontal application of Betonamit Type S

Should there be no possibility to drill the holes in a vertical direction, Betonamit Type S comes into its own. In contrast to liquid Betonamit Type R, this kneadable material can be processed into ‘sausages’ and thus stuffed into horizontal boreholes.
