What Hole Spacing Is Recommended for HSCA Rock Splitting?

The recommended hole spacing for HSCA (soundless cracking agent) depends on the rock hardness, hole diameter, and desired cracking direction.

In most quarrying and demolition applications, the typical spacing between drilled holes is usually 30 cm to 60 cm. For very hard rock such as granite or basalt, the spacing may be reduced to ensure efficient cracking.

Proper drilling patterns are important when using expansive mortar. Holes should normally be drilled in a straight line along the intended splitting direction.

Using reliable pneumatic rock drills, drill rods, and drill bits helps achieve accurate hole spacing and depth, ensuring the best rock splitting performance.
