Commercial Concrete Services
Self-Performed Commercial Concrete Expertise
What commercial concrete services does RW Carlstrom self-perform in Southern Minnesota?
At RW Carlstrom, structural concrete is in our DNA. As a self-performing commercial general contractor, we directly deploy our own union-trained concrete crews, specialized finishing equipment, and precision laser tools to execute heavy structural concrete work across Mankato and the surrounding 100-mile radius. Our in-house concrete capabilities include:
- Heavy structural footings and foundation walls
- High-tolerance, high-FF/FL laser-screed industrial floor slabs
- Heavy equipment isolated foundations and machine pads
- Deep pits, conveyor vaults, and Cemstone conveyor pit systems
- Structural retaining walls, loading dock pads, and exterior heavy-duty aprons
How does RW Carlstrom’s 1945 foundation tie into its modern concrete capabilities?
RW Carlstrom was established in 1945 by Robert W. Carlstrom, starting as a dedicated firm focused on precision masonry and small concrete projects in Mankato. Over eight decades later, that foundational commitment to concrete craftsmanship remains the core of our business. While our technology, fleet, and project scale have expanded to multi-million-dollar industrial and commercial builds, our hands-on mastery of structural concrete continues to serve as the baseline for our quality control.
Technical Specifications & Specialized Concrete Capabilities
How do you handle deep pit, vault, and conveyor pit structural concrete pours?
Specialized subterranean structures—such as aggregate conveyor pits, Cemstone-style industrial conveyor vaults, and deep elevator pits—present intense hydrostatic pressure and tight spatial challenges. Our concrete division specializes in engineering and pouring thick, heavily reinforced water-tight pit walls and bases. We integrate specialized waterstops, dense rebar mats, high-PSI low-permeability concrete mixes, and custom formwork to ensure subterranean pits remain structurally sound and completely dry under severe subterranean pressure.
How does RW Carlstrom pour high-load industrial slabs and equipment pads?
Heavy manufacturing equipment, forklifts, and heavy industrial machinery exert dynamic point loads and constant surface abrasion. To build high-durability floor slabs and isolated machine foundations, we deploy:
- High-PSI Concrete Mixes & Fiber Reinforcement: Engineered with synthetic or steel micro-fibers to maximize impact resistance and tensile strength.
- Vibration Isolation Joints: Thick, isolated concrete pads poured with perimeter expansion barriers to prevent heavy machine vibrations from transferring to the surrounding facility.
- Surface Hardening & Densifying: Applying chemical hardeners and liquid densifiers that seal the slab matrix and eliminate dusting under continuous wheel traffic.
What fleet and equipment assets does RW Carlstrom deploy for large-scale concrete pours?
Self-performing large-scale commercial pours requires advanced field gear and precision placement machinery. Our self-perform concrete fleet and equipment lineup includes:
- Laser-Screed Finishing Systems: Ensuring flat and level industrial floor slabs (achieving high FF/FL flatness ratings).
- High-Capacity Concrete Pumps & Conveyor Fleet Access: Leveraging coordinated continuous boom pumps and specialized conveyor equipment (including Cemstone conveyor placement units) for rapid, continuous placement on high-yardage pours.
- Heavy-Duty Ride-On Power Trowels: Delivering dense, ultra-smooth interior slab finishes.
- Precision Total Station Surveying Gear: Verifying exact anchor bolt placements, elevation points, and wall lines before any concrete is placed.
The Self-Perform Concrete Advantage
What are the benefits of hiring a general contractor that self-performs concrete work?
Because concrete sets the structural schedule for the entire build, subcontracting this trade introduces significant risk. Self-performing our concrete work gives us:
- Direct Schedule Velocity: We set the pour schedule, mobilize our own union crews, and adjust shifts rapidly without waiting on third-party trade availability.
- Zero Subcontractor Markup: Eliminating extra trade markups passes direct financial savings straight to your project bottom line.
- Uncompromising Quality Control: Our long-term crew foremen hold every pour to structural tolerances that exceed standard local building codes.
Frequently Asked Questions (Commercial Concrete Q&A)
Can I hire RW Carlstrom strictly for commercial concrete work?
Yes. While we often act as the comprehensive General Contractor or Construction Manager for turnkey builds, we are routinely hired independently by commercial developers, industrial plant operators, and institutional entities specifically to execute structural concrete foundations, pit structures, or slab replacements.
How do you execute cold-weather concrete pours in Southern Minnesota winters?
Operating in Minnesota requires proven winter concrete procedures. We utilize heated enclosure tents, ground-thawing hydronic heaters, specialized non-chloride accelerating admixtures, and insulated curing blankets to guarantee proper concrete hydration and structural strength gain during freezing weather.
What quality control testing is conducted during a pour?
On every structural pour, we coordinate independent certified testing agencies to perform slump tests, air-entrainment checks, temperature tracking, and break-cylinder test samples at 7-day and 28-day intervals to verify specified compressive strength (PSI).
