A powder that when mixed with water and poured into pre-drilled holes will crack concrete or stone within 4 hours.

THE CRACKER is a non-explosive cracking agent which enables standard demolition to be carried out with comparative accuracy, without the need for special preconditions or equipment. The Cracker is supplied in powder form and is sealed in a handy plastic containers.

The ideal drill hole diameter is maximum 1-1/4” in
hot weather (above 72° F) and maximum 1-1/2” below 72° F.

Blow drilling dust from holes and remove any water.
Allow holes to cool from friction of drilling.

The Cracker must be mixed with a specific amount of water.

Begin mixing The Cracker and water with a “jiffy-mixer”
attachment in a 1/2" electric or pneumatic drill.
Mix only until smooth, pourable liquid consistency develops (almost no lumps).

Pour the mixed Cracker directly from bucket into clean,
pre-drilled holes immediately upon achieving a smooth liquid consistency.
(TIME ELAPSED SHOULD NOT EXCEED FIVE (5) MINUTES FROM BEGINNING TO MIX).

Cover holes with wet cloth if personnel will remain in the area,
or if holes are exposed to sunlight in high temperatures.

After a few hours reaction time, The Cracker develops an extremely high expansion pressure which quickly increases to such an extent that any hard stone or reinforced concrete is broken. 

Compared with a number of other conventional methods of demolition, The Cracker is virtually noiseless and free from vibration. It is, moreover, ECOLOGICALLY BENEFICIAL.
