Walker Aggregates products – crushed limestone, sand and gravel – support the infrastructure needs of our communities and beyond. We participate in the circular economy by recycling asphalt and concrete at several of our locations. Norjohn Contracting provides the public and private sectors with pavement preservation strategies that maintain quality roadways sustainably extending the life of our road networks while they are still in good condition. It reduces energy use, non-renewable resource consumption and greenhouse gas (GHG) emissions. We also provide underground servicing, site development and traditional road reconstruction services.
