Non-explosive demolition agents are chemicals that are an alternative to explosives and gas pressure blasting products in demolition, mining, and quarrying.[1] To use non-explosive demolition agents in demolition or quarrying, holes are drilled in the base rock as they would be for use with conventional explosives. A slurry mixture of the non-explosive demolition agent and water is poured into the drill holes. Over the next few hours the slurry expands, cracking the rock in a pattern somewhat like the cracking that would occur from conventional explosives.
Non-explosive demolition agents offer many advantages including that they are silent and do not produce vibration the way a conventional explosive would. In some applications conventional explosives are more economical than non-explosive demolition agents. In many countries these are available without restriction, unlike explosives which are highly regulated.
The active ingredient is typically calcium oxide, "burnt lime," and is typically mixed with Portland cement and modifiers.
These agents are much safer than explosives, but they have to be used as directed to avoid steam explosions during the first few hours after being placed.

You do not need explosives for every demolition job. Most people assume that for a demolition to be a demolition there is a need for a kaboom. It does not have to be that way. As a leading demolition contractor in we are experts of non-explosive concrete demolition.
Non-explosive concrete demolition is a process that relies on chemical agents to safety remove concrete and rock during the demolition process.
This is a viable alternative to explosives especially in situations where there is a high risk of injury posed by explosives or where vibrations caused by explosives could damage nearby structures.
The advantages of non-explosive concrete demolition are:
There are chemical agents that we use like buster or we use hydrodemolition to carry out the job. Both these methods offer you versatility and options that you do not get when you are using traditional methods like jackhammers and explosives.
This is just an example of why you should consider Manchester Demolition for your projects. We are committed to making sure that people and the environment do not suffer from the effects of demolition.
