Rieger ContractingWe completed precision indoor rock blasting inside an existing island building to excavate space for a cold plunge spa tub. To execute the work on the island, we staged our 3.5-ton excavator on-site in late fall and hauled the remaining rock drilling and blasting equipment over the ice road during the winter. Using blast mats and careful containment, we broke out the bedrock foundation within the wooden structure. Once excavation wrapped up, we safely demobilized all machinery back across the frozen lake before rising temperatures melted the ice road.

We use a project called NxBurst. It’s great for small jobs as it’s very safe and easy to use. How to control a blast like what we did here really just comes from experience. This was a 3 week job. Lots of small blasts in order to preserve the building. Also excavating the hole took a very long time reaching in with the excavator. Blast mats were needed for safety.

How do you determine how to blast it? I know so little about this. Like is there a calculation you have to do? Or you just drill in tnt, put the mat on top and hope for the best?
