Crushing & Aggregate
Overview
Turn what's already on site into the aggregate your project needs
The Kolb Grading team offers crushing and aggregate processing services to reuse materials that would otherwise end up in a landfill or dump, saving your project time and money. As the construction industry has grown year after year, so has the demand for quality aggregate on every kind of project. That makes it vital to have a partner you can rely on to produce and deliver the material you need, and it’s an area where Kolb excels with our on-site crushing and aggregate processing.

Problems we solve
Where on-site crushing pays off
01
Costly haul-off & disposal
On-site crushing turns demolition debris into usable material, cutting truck trips, disposal fees, and the fuel spent hauling waste away.
02
Material reuse & recycling
Asphalt and concrete are reclaimed into recycled base and fill, so existing resources go back into the project instead of a landfill.
03
Spec compliance
Screening and gradation control produce consistent, spec-compliant aggregate you can rely on for every application.
04
Site logistics & safety
Portable plants set up where the material is, reducing truck traffic, safety exposure, and the environmental footprint of your operation.
Reusing what's already on site is the smartest aggregate you can buy. We make it.
