Demolition & Blasting
Overview
Demolition and blasting, engineered and self-performed
Kolb Grading is an experienced demolition and blasting contractor working in St. Louis, MO, and nationwide. We carry out commercial, industrial, and highway demolition, above and below water, alongside controlled and explosive blasting for rock excavation, roadcuts, and subsurface utility work. Being based in the Midwest keeps our crews working with limestone, granite, shale, and track-rock year-round, so we bring hard-won experience and specially developed drilling and blasting procedures to every job.
Full scope
Everything from teardown to hauled-off, under one contract
Demolition and blasting isn’t one task. It’s a coordinated program of survey, permitting, controlled removal, and recycling. Kolb self-performs and manages the full scope, so nothing falls between subcontractors.

Problems we solve
The hard removals other contractors won't take
01
Reinforced concrete & rock
No two pieces of reinforced concrete are alike. Locks, dams, and power plants get specially developed drilling and superior blasting procedures to break them out cleanly.
02
Vibration & neighboring structures
Third-party pre- and post-blast inspections and controlled, precisely timed shots keep vibration in check and structures within 500 feet protected.
03
Hazardous materials & compliance
Asbestos awareness, OSHA engineering surveys, and full permit and explosives management keep every teardown compliant and documented.
04
Disposal cost & waste
Salvaging, segregating, and recycling concrete and steel cut haul-off volume and turn demolition debris into reusable material.
Any structure down, any rock out. Done safely.
Safety
Safety is a culture, not a number.
For us, safety is more than an EMR figure. It’s how every crew shows up, every day. From daily planning and hazard analysis to ongoing crew training, we build safety into the work so our people go home safe and your project stays on track.
Daily hazard analysis
Every crew plans the work and the risks before it starts.
Ongoing safety training
Continuous training keeps our people sharp and certified.
Documented compliance
Full reporting and inspection coordination on every job.
