crusher breaks down the impact of concrete pavement on surrounding houses

What is Crusher Run? | TriStar Concrete

Crusher run is a blended mix of coarse aggregate and fine aggregate. The combination of both crushed stone and stone dust creates a low void content (the amount of space or air between the pieces of rock in a mix) that is valuable in concrete construction for its compaction ability and drainage characteristics.

6 Types of Concrete Cracks and What They Mean | …

Since concrete cannot shrink around a corner, stress will cause the concrete to crack from the point of that corner. Plastic shrinkage cracks are typically very narrow in width and barely visible. While nearly invisible, it is important to remember that plastic shrinkage cracks don''t just exist on the surface, they extend throughout the entire thickness of the slab.
