What is Crack Dexpan
Crack Dexpan is a soundless and safe demolition agent which is quite different from ordinary demolition agents such as explosives and dangerous materials. It does not cause any fly rock, noise, ground vibration, gas, dust or any other environmental pollution when used properly.

As requirements for demolishing rock and reinforced concrete in construction increase in tight quarters, the use of explosives and explosive agents is becoming more restricted as far as safety and environmental pollution problems are concerned. Crack Dexpan is the solution.

Crack Dexpan is a powder with amazing 18,000 PSI expansive strength when mixed with common water. Poured into holes, Crack Dexpan breaks reinforced concrete & rock safely and quietly, while providing SILENT cracking.
Since Crack Dexpan provides controlled demolition according to drilling patterns, it is very easy to break reinforced concrete and all kinds of stone into desired sizes and shapes, without noise, vibration or dust.
Reinforced Concrete
Demolition & Cutting
 

In demolition, concrete cutting & excavating industry, Crack Dexpan helps you to break reinforced concrete and rock into chunks, so you may easily cut off rebar, haul it away with a crane or truck without damage remaining part.
 
Rock Breaking & Excavation
 
In mining and quarrying industry, Crack Dexpan helps to achieve perfect slabs and blocks from limestone, onyx, marble, granite or any other type of stone you are working with. Compares to blasting, Crack Dexpan avoids waste of valuable stone, high insurance, costly storage and labor.
 
Stone Quarrying & Dimension
 
Crack Dexpan can also be applied along with traditional methods like primer cord, hydraulic breaker, diamond blade saw and jackhammer to help cut cost, work time and increase safety, Plus its silent operation, Crack Dexpan is perfect for residential, school, hospital and airport area.
 
Alternative to Blasting, Breaker,Jackhammer, Diamond Saw ...
Crack Dexpan helps your work to become more efficient and cost effective.

Depending on usable temperature, there are 3 types of Crack Dexpan:
  Crack Dexpan I – (usable temperature of 77 ~ 104oF or 25 ~ 40oC)
Crack Dexpan II – (usable temperature of 50 ~ 77oF or 10 ~ 25oC)
Crack Dexpan III – (usable temperature of 23 ~ 50oF or -5 ~ 10oC)
Package & Storage
Container and Storage Crack Dexpan is packed in 4 anti-moisture bags of 5 kg (11 lb.) each and then placed in a water proofed carton with a total weight of approximately 20 kg (44 lb.).
 ◆
AlthoughCrack Dexpan is packed in anti-moisture paper bags, long storage may cause deterioration of its working ingredients. Therefore, store in a dry place and use it as soon as possible.
When storing, do not place the bags of Crack Dexpandirectly on floor, put them on a pallet and keep in a dry warehouse etc. Crack Dexpan, stored in this manner, can be effectively used for about 1 year.
Crack Dexpan should be unpacked before use.
When storing the portion of Crack Dexpan remaining after use, push the air out of the bag, then seal with gum tape and use as soon as possible. However, as it may get exposed to moisture there is a risk of Crack Dexpanlosing its effectiveness once the bag has been opened.
If you receive broken bags of Crack Dexpan, they may not work due to chance of moisture absorption.
