The basic procedure is to mix BETONAMIT® powder with water to create a slurry that you pour into holes, cracks and other entrances in the piece of rock, stone, or cement that you want to crack up into pieces and then remove.
Be sure to watch the video at the bottom of our home page.
You can vary the percentage of water to powder depending on where you want to put the mixture. You can add more water to make the mix thinner so it pours into cracks and orifices. You can also make the mix more like putty so it sticks into vertical cracks and overhead holes.
You can follow the steps illustrated below when pouring BETONAMIT.
You can follow these steps when making a putty.
Positioning bore holes
Cracking always occurs in the direction of lowest resistance. A larger bore hole diameter results more force, shorter reaction time and wider cracking. A tighter spacing of boreholes results in smaller fragments and a shorter reaction time.
Separating and splitting
To separate and split large rocks or pieces of concrete, drill the holes in a line with short space between the holes. Cracking occurs from hole to hole. In this way, objects can be precisely separated.
Breaking up concrete and large rocks
Drill boreholes offset in several rows to obtain the smallest possible fragments. The more boreholes, the smaller the fragments. Cracking occurs in a crisscross pattern.
Digging and removal
If there is no free side available for displacing the material, you can create the space. Drill opposing boreholes at an angle of 35-60° on two sides or on one side at an angle of 45-60°. Angled boreholes are also suitable when you want to do a large scale lowering of the ground level, for example, when digging a cellar.
Rock extraction and demolition
There are several techniques for extracting and demolishing rocks. Select the drilling method according to the shape and constitution of the rock adapted to local regulations. The principle remains the same: Try to create a free side, that is, a straight edge, then begin extraction or demolition from the edge and continue as far as is required.
Drill boreholes and fill in several rows five to 10 inches (10-15 cm) below the required ground level. The substrate will be broken and loosened such that it can then be removed by excavator by hand. The non-explosive cracking agent is most effective when the boreholes are drilled obliquely so that part of the force is exerted upwards.
