We’ve worked closely with the City of Ottawa on a number of recent projects, such as the West End pumping stations, Alta Vista culvert replacement, and the John Asselford Weir removal.

Before we can even get started with any drilling or blasting, we have to be very careful about the location and the nature of the rock that we’re working in.

This is especially important for drilling into hard rock like granite or limestone, as these materials are likely to have sharp edges that could cause injury if they’re hit by mistake. There are also a variety of different types of rock that can be used for drilling depending on their properties, including sandstone, quartzite and shale.

Each of these materials has its own advantages and disadvantages so you need to choose the right one for the job. For example, shale tends to be a bit softer than granite, while quartzite is a lot harder and less brittle than both of them.

Ultimately, it’s up to you to decide what works best for your project.
