Madsen Construction, Inc.

Concrete cutting and removal contractors saw, drill, break and haul concrete on everything from a cracked patio to a doorway through a foundation wall. The tools are specialized: walk-behind slab saws with diamond blades for flat cuts, track-mounted wall saws for straight openings, core drills for round penetrations for pipe and conduit, and hydraulic breakers or robotic demolition machines for bulk removal. Wet cutting controls silica dust, which OSHA regulates tightly, but produces slurry that has to be contained and disposed of rather than washed into a storm drain. Because a saw cannot see rebar, post-tension cables, conduit or radiant tubing inside the slab, a GPR scan before cutting is standard practice on any structural or unknown concrete, and cutting a post-tension slab without one can be dangerous.

Excavation contractors dig and move earth for foundations, basements, utilities, pools and site cuts. Most residential jobs run on a mini or mid-size excavator paired with a skid steer and a dump truck; larger cuts bring in a dozer or scraper. The price depends less on the size of the hole than on what is in the ground: clay, ledge rock, high groundwater and buried utilities all slow the machine down and change the hauling math. Before the bucket touches dirt the site needs an 811 utility locate, and any trench deeper than five feet needs a protective system under OSHA rules.

Hauling contractors move bulk material to and from job sites: delivering gravel, sand, topsoil and fill, and removing excavated spoil, concrete and demolition debris. Pricing is built around truck size and cycle time. A tandem dump truck carries roughly 10 to 14 cubic yards, a tri-axle 15 to 18, and a belly dump or end dump trailer over 20; the driver's rate covers loading, travel, dumping and any wait time at either end. Distance to the pit or landfill is often the biggest variable, and tipping fees for debris are usually passed through separately. Contractors who also run a loader or excavator can load their own trucks, which matters when nothing on site is available to fill them.
