1. Boring Holes
Borehole diameter: Ø min. 30 mm | Ø max. 40 mm
Borehole depth: The borehole depth must be at least 5-times the borehole diameter.
The boreholes must be clean and dry.
Important: Because BETONAMIT® contains unslaked lime, during the entire work process goggles and protective gloves must absolutely be worn.
Charge BETONAMIT® into a suitable container. Add one liter/5kg of cold and clean water to the mixing bucket. Mix slowly in the beginning. Mix it until “lump-free” by means of a stirring paddle for about 2 minutes until it becomes a homogeneously, flowable mass.
3. Filling the Boreholes
Slowly pour BETONAMIT® into the boreholes. The BETONAMIT® subsequently hardens and corks itself. Additional mechanical closures are not necessary.
After filling the holes the BETONAMIT® slowly starts to build up pressure.
Depending on the ambient temperature and the intrinsic temperature of the object to be blasted, the blasting process requires between 4 and 12 hours on an average.
Tip: Betonamit continues to expand over several days. This means that the more time you give Betonamit to work, the easier the subsequent removal of the fragments will be.
