Mass amounts of rock can be an all-out nightmare when you are planning a construction project. Thankfully, there are a lot of professionals with tools, equipment, and insight to help you get rid of them. When you need to get rock removed as quickly and efficiently as possible, you are likely going to spend some time investigating the different methods for removal. Two of the most common ways professionals tackle mass amounts of rock is with blasting and trenching. Here is a look at some of the differences between the two and the things you may want to know as a prospective customer. 

1. Blasting can cause more localized disruption beyond just the rock. 

Blasting has been used for many years to clear rock in a construction zone, and it is an effective solution. However, blasting can also cause a lot of disruption in the blast zone. All areas have to be properly prepared before the blast, proper permits have to be secured, and even local structures have to be assessed and prepared for the work. Trenching is not as disruptive; the only permits required will likely be associated with bringing in the equipment, which is far easier to get. Likewise, trenching is not going to pose threats to surrounding structures. 

2. Blasting can be a quicker way to eradicate rock than trenching. 

Obviously, blasting can be one of the faster ways to break up the rock. The contractors will go in, strategically place the blasting materials, hit a button, and then get to work doing the clearing. The process can be faster, but this rapid speed can also come at a price. Trenching gives a more controlled way to remove the rock. The process may take slightly longer, but in return, you can achieve higher levels of ground stability and may have a smaller mess to clean up when all is said and done. 

3. Blasting doesn't always leave you with a clear cut area. 

There is only so much control that can go into blasting, even though it is an effective way to clear rock from the area. The areas where the blasting mediums are placed can sustain larger blows that have to be later repaired in order to prepare the ground for the next phases in the project. For example, if you are creating a trench, you may have to go back in after blasting to rebuild the sidewalls of the trench. With typical trenching methods, this would not be required.
