Cold blasting agent – meaning and classification
Cold blasting agent is still widely searched, especially in translated product listings. It is understandable, but the word blasting misrepresents the product.
What does the term mean?
Cold blasting agent describes an expansive powder as a blast that produces no heat, no flame and no detonation – hence „cold“.
The product is identical to an expansive demolition agent. Only the framing differs: it is described as a variant of blasting rather than as its own method.
Where does the name come from?
When the technology arrived in the 1970s, blasting was the reference point for everyone on site. Calling it cold blasting made the benefit instantly clear.
The wording is also a direct translation of terms used in German and other European languages, which is why it appears so often in imported product listings.
Where is the term used?
Found in older catalogues, in translated online listings and in everyday speech on site.
Largely avoided in modern safety documentation because of the reference to blasting.

Is the term technically unambiguous?
No. There is no blast at all – no ignition, no shock wave, no flying debris – so describing the product as any kind of blasting agent is misleading.
In dealings with authorities, clients or neighbours the term can create concerns that the product does not justify. Expansive demolition agent or NEDA is the better wording.
How does the product work?
The powder is mixed with water and poured into boreholes. Over several hours the expansion pressure exceeds the tensile strength of the material and cracks form.
The reaction is mildly exothermic, so the borehole warms slightly – but there is no combustion and no flame at any stage.
Typical applications
- Demolition where explosives are prohibited
- Work without a blasting licence
- Interior and confined-space demolition
- Boulders and rock steps
- Foundation removal

Frequently asked questions
+Is cold blasting an actual blast?
No. Nothing detonates and nothing burns. The material cracks under slowly rising pressure.
+Does the product get hot?
The reaction releases some heat and the borehole warms noticeably, but there is no flame and no risk of ignition.
+Which term should be used in documents?
Expansive demolition agent or NEDA, because both describe the product without implying an explosive.
