At Lenmark, we understand that not every project follows straight lines—or comes with straight answers. Especially when it involves curved concrete walls. They’re aesthetically appealing and trending, but forming them isn’t always straightforward. That’s where we come in. We provide expert solutions through our industrial marketplace, offering innovative equipment for your everyday challenges. Two such solutions making waves is the Symons Flex-Form Flexible All-Steel Gangform System and PERI Circular Wall Formwork Systems—both reliable methods for forming curved concrete walls without the headaches of traditional techniques.
You know how to get the job done, so rather than telling you how to do it, let’s explore the curved concrete solutions available in the marketplace and find ways to make your job easier.
Symons Flex-Form Flexible All-Steel Gangform System
Buying used means skipping the premium price tag without sacrificing quality. If your budget needs to work as hard as your equipment does, this is the way to go.
- High Load Capacity: Supports up to 1,200 pounds per square foot (psf) of pressure, accommodating substantial concrete loads.
- Excellent Concrete Finish: The steel skin plate flexes to form the desired arc, preventing the “chording” effect seen in conventional systems. Unlike traditional panel systems that leave joint marks requiring grinding, the Flex-Form system creates smooth surfaces with minimal finishing labor.
- Fast and Simple Erection: No expensive templates, floppy panels, or bolts to torque—start building the Flex Form gang immediately.
- Adaptability to Various Radii: The system adapts to any radius of 5 feet and above, offering flexibility for diverse design needs.
- Durable Construction: Features a 3/16-inch steel face with integral 4-inch deep vertical stiffeners, ensuring a smooth finish and extended lifespan.
- Pre-Set Radii: Factory-rolled steel ribs are pre-set to the required radius, eliminating the need for custom templates and reducing on-site labor.
- Complete System: Comes with a full set of accessories for various project requirements and is fully rentable, allowing flexibility for different project scopes.
PERI Rundflex Circular Wall Formwork System
For those looking to form large-diameter circular structures with speed and precision, the PERI Rundflex system delivers on all fronts. Built for efficiency and repeatability, it's a trusted solution for water tanks, silos, curved facades, and more.
- Integrated Adjustment Mechanism: Easily adjustable to various radii using built-in spindles operated with a combi ratchet spanner—no need for additional tools or custom pre-bending.
- Fast Radius Setting: Radii can be adjusted directly on-site, even when assembled, using templates and spindles with self-cleaning hexagonal threads—saving significant setup time.
- Compatible with PERI Systems: Designed to integrate seamlessly with other PERI wall formwork systems, such as TRIO, using the BFD Alignment Coupler, making it ideal for hybrid projects.
- High-Quality Finish: Steel facing provides a smooth surface finish, reducing the need for extensive post-pour treatment.
- Modular Flexibility: Forms complete circles or arcs with repeatable accuracy, reducing labor and increasing consistency.
- Durable and Reusable: Robust design stands up to repeated use across multiple projects with minimal wear.
- Ideal for Large-Scale Curves: Perfect for industrial and infrastructure builds where consistent curvature and high efficiency are critical.
Why Choose Curved Concrete Walls?
If you’re reading this, the project is probably already established—but why was curved concrete chosen? We all know curved concrete walls aren’t just about looks (though sometimes they are). They come with real functional advantages that make them a smart choice for certain projects:
- Ever see a square hockey rink? From hockey rinks to stadiums, curved walls shape the infrastructure of sports facilities, aiding in seating arrangements, crowd flow, and structural integrity.
- Adaptive Design: Whether working with tight spaces or softening harsh angles in an architectural layout, curved walls allow for creative, flowing designs that straight walls can’t achieve.
- Better Acoustics: In spaces where sound control matters—like auditoriums, stadiums, or performance halls—curved walls help disperse sound evenly, reducing unwanted echoes.
- Structural Strength: Curved walls distribute pressure more effectively than flat ones, making them ideal for areas with high winds, heavy loads, or seismic activity.
- Low Maintenance & Longevity: Once built, curved concrete walls require minimal upkeep and offer long-term durability compared to other materials.
- Great for Landscaping & Outdoor Spaces: Retaining walls, garden partitions, and tiered seating areas benefit from curved walls, adding a dynamic, natural flow to landscapes.
Material Handling Solutions for Curved Concrete Wall Projects
Forming the concrete is just one part of a much more complex project. We also offer solutions for lifting, transporting, site prep, maintenance, and more!
Lifting and Positioning Equipment
- Cranes and Hoists: Essential for lifting heavy formwork panels and concrete elements into place. Our range includes equipment for various load capacities and site conditions.
- Forklifts and Telehandlers: Ideal for transporting materials around the construction site, offering versatility for different load types. Diesel forklifts are particularly useful when working on varied terrain.
Concrete Transportation
- Concrete Buckets: We offer used concrete/cement buckets—an affordable way to cut costs without compromising efficiency.
- Conveyor Systems: Facilitate the smooth movement of concrete from mixers to the pour site, reducing manual labor and improving workflow speed.
Site Preparation and Maintenance
- Ground Heaters: While the ground may be thawing now, a ground heater like the Hydronic Ground Heater can be essential for curing concrete in colder climates, ensuring optimal structural integrity.
- Site Offices: Need an on-site command center? Sea Can offices help keep your team organized, store materials securely, and ensure your project runs smoothly.
Partnering with Lenmark
Building curved concrete walls takes more than just the right formwork—it’s about the right tools, the right approach, and keeping the job moving. Getting the curve right is key, but so is everything that comes before and after the pour. From site prep to material handling and ensuring smooth operations, every step demands the right equipment and solutions.
Whether you're replacing a forklift that’s on its last forks, upgrading your material handling equipment, or making smarter moves to keep your warehouse running efficiently, Lenmark’s industrial marketplace is here to help you find the right fit—without the hassle.
