Grey Rock Materials offers commercial and residential asphalt services in the Moncton and surrounding areas. Not all asphalt coatings are equal! We are sure you have seen roads or driveways that have cracked and crumbled. This is typically due to improper installation and / or cheaper materials. We use only the BEST materials in all our products. Also we lay more asphalt for a thicker layer, eliminating pre-mature wear and surface failure. Sometimes saving a few bucks can cost you MUCH MORE down the road, if the surface fails.
