Crackit User Manual

Boulder removal, rock splitting, quarrying, and concrete demolition can all run without explosives. Crackit is a powder that expands when mixed with water — fill your drilled holes, wait for cracks, then remove the pieces. The guides on this site cover planning, hole layout, mixing ratios, and what to expect at different temperatures.

Checking material temperature

Lower a thermometer to the bottom of a drilled hole and leave it for 2–3 minutes, then read it quickly on the way out. Don't measure immediately after drilling — friction heat will give you a false high reading. The temperature of the stone or concrete itself (not just the air) decides which mix adjustments you need, so this step comes first.
