Very Easy Only Three Steps: Drilling, Mixing&Pouring, then Waiting for cracking within 2hours!

First drill a hole in the blasted object.

Second, pour some of the produce into the bucket with water, the proportion of water and supplies is 1:3, and then stir it into a paste.

Third, slowly pour it down the hole and fill it with the lid uncovered.

Fourth, about 2hours later, the object blast. whatever time you can choose as required.

The process in short: drilling-stirring-pouring-blasting

Hole Diameter:

The diameter of drilling has a great effect on the explosion, so if it is too small, it will not explode well. On the contrary, if it is too big, it will be easily too strong. A bit with a diameter of 30-40mm is better.


30-50cm for reinforced concrete

10-15cm for marble

5-10cm for granite




Usable temperature


40°C-50°C ( 104°F-122°F)

Cracking Mechanism

Fig. 1 Fracture mechanism by the expansive stress of Non-explosive demolition / cracking agent

Fig. 2 Sectional-view of the crack formation in the material with two free surfaces

When multiple numbers of holes are filled with Non-explosive demolition / cracking agent, that are properly adjacent to each other, the cracks from the hole propagate to connect with the neighboring holes, as shown in Fig. 3.

It is therefore possible to determine the directions of the cracks as planned by appropriately arranging the hole spacing and its depth and its inclination.

Establishment of free surface:

In the case of trenching, shafting or tunneling, if all holes are drilled vertically and filled with Non-explosive demolition / cracking agent, the crack width can not increase but horizontal cracks initiate. Therefore, in order to obtain two free surfaces, inclined holes or pre-splitting must be required.
