Services
Concrete Cutting
Con-Cor Company provides precision concrete cutting for commercial and infrastructure projects. Our services include flat sawing, wall sawing, and wire sawing using diamond blades for clean, accurate cuts. We handle projects ranging from utility installations to structural modifications, ensuring minimal disruption and compliance with safety standards.
Core Drilling
Our core drilling services create precise openings in concrete for HVAC, plumbing, and electrical systems. Using electric or hydraulic rigs, we drill holes from 1" to 57" in diameter with depths exceeding 80 feet. This method preserves structural integrity while accommodating complex project requirements across industrial and commercial sites.
Equipment Sales
Con-Cor Company sells top brands like Stihl, Honda, and Wacker for concrete cutting and drilling. Our inventory includes core drills, saws, diamond blades, and safety supplies. We also offer parts and repair services, with factory-trained technicians ensuring equipment longevity and optimal performance for contractors in Wisconsin and the Midwest.
Wire Sawing
Wire sawing addresses complex cutting challenges where traditional methods fail. Using diamond-segmented wire, we cut reinforced concrete, steel, and rock in confined spaces or underwater. This technique is ideal for bridge removals, silo demolition, and large-scale infrastructure projects requiring high-precision solutions across the Midwest.
Specialty Demolition
Our specialty demolition services include curb cutting, concrete grinding, and scarifying for structural modifications. We use advanced equipment to remove or reshape concrete with minimal vibration, ensuring safety and precision. These services support transportation projects, ADA compliance upgrades, and industrial facility renovations throughout Wisconsin and neighboring states.
