regulatory environment of the region. According to Brian Priestly, Vice President of Operations, equipment selection is important for reducing dust and noise in urban environments. “We try and use a lot of hydraulic crunchers or processors to diffuse the noise,” he said. “Hammers are needed sometimes, but in the prep of the concrete and the processing of larger oversized concrete we’ll use a processor to break it down as well, as it’s a great tool to remove steel from the concrete, then recycle after the fact.” Priestly Demolition’s demolition equipment was outfitted with primary processors to pre-crush the concrete. “We use the processors to pulverize the material to allow a more efficient crushing process. Sufficient water is required to ensure no risk of silica dust is present for workers or the public,” said Priestly. Demolished material is typically crushed to at least four-inch minus and some customers seek two-inch minus for subbase and compaction ability. “We can/will crush to a customer’s specification,” said Priestly. “Currently in Ontario there is a demand for recycled product. There is a surplus in crushed asphalt but concrete and/or stone is going out the door as quick as you can make it.” Priestly Demolition uses both jaw and impact crushers to process material on urban jobsites, and Priestly said that
the company tries to purchase the same brand, same size and same equipment to ensure that they are able to easily stock and replace parts as needed. When it isn’t feasible to crush on
site, the destination of the material depends on customer requirements. Priestly Demolition has the ability to take it to their yards to crush; they can remove and recycle the steel, then
crush the rest to hopefully salable aggregate, said Priestly. “We try and determine all the crushing requirements at the tendering process with the customers.” HEG
