I remember as a child riding through highway construction zones around Peterborough and Haliburton, where they would demolish rock outcroppings to allow levelling and straightening the road. There were similar mats used there. I think they put them on top of the rock being demolished to prevent small pieces from flying off. I’d be a bit surprised to find they need to do that in downtown Kitchener however — even the deep excavation for the QNC at the University of Waterloo didn’t get anywhere near bedrock.
There is definitely no bedrock. But they will be breaking through the concrete wall that is next to the blasting mats in the photo.
Yikes!
