Cosinus Slide® Joint
The Cosinus Slide® armour concrete floor joint is by far the strongest armored joint for concrete industrial floors.
Designed to meet the most demanding current and future needs of an industrial concrete floor.
The strength of the industrial floor is determined by how concrete slabs are connected. The difference between joint solutions is happening below the surface.
Why Cosinus Slide ® joint?
- First, most visible and easiest to understand: It has the best edge protection on the market. A vertical sinus wave shape on top of the floor removes vibrations and neutralizes wheel impact.
- Second, less visible, yet most important from a technical standpoint: It has the best "continuous" load transfer system on the market. A second sinus wave in the middle of the floor, in combination with the continuous 3D anchorage system, reinforces the load transfer over and throughout the joint.
Built to Last. Engineered to Perform.
Advantages of the Cosinus Slide® armour joint
Hover over each advantage to see how our patented design solves key structural challenges for engineers while saving massive maintenance and concrete costs for building owners.
No dowel technology
Prevent Squeezing & Cracking
The Problem: Traditional steel dowel plates restrict the natural expansion and shrinkage of concrete slabs, forcing the floor to crack under stress.
Our Solution: By eliminating point-source dowels entirely, our system allows the floor to contract freely and naturally. You get a completely crack-free slab without weak points.
3D anchorage system
Locked in the Concrete Forever
How it works: Our crossed steel reinforcing system anchors the joint deep inside the concrete in all directions (horizontally and vertically).
The Benefit: Traditional jointsget loose and bumpy under heavy forklifts. The 3D Anchorage locks the joint into the floor so it never moves or breaks.
Continuous load transfer system (Double slide effect)
Smooth, Continuous Weight Transfer
The Engineering: Traditional joints transfer weight in steps, putting strain on concrete edges. Our patented "double slide" geometry acts like a continuous bridge.
The Benefit: Extreme loads (machinery or heavy trucks) slide effortlessly from one slab to another. No concentrated stress, no slab rocking, and no concrete failure.
No deflection and no curling
Goodbye Bumpy, Warped Edges
The Issue: Concrete edges naturally warp upward (curling) as they dry, causing dangerous vertical "lips" that trip forklifts.
The Benefit: Our interlocking sinusoidal shape holds both slab edges completely flat and aligned. It prevents vertical deflection, meaning your warehouse floor stays permanently level.
Shock and vibration free
Smooth Gliding. Zero Vibrations.
The Experience: Forklifts usually "clank" loudly when passing traditional joints, shaking the cargo and jarring the driver's spine.
The Benefit: Because the wheels cross on a continuous sinus-wave line, they never fall into a gap. Forklifts glide over joints with absolute silence, protecting equipment, goods, and worker health.
Optimize floor thickness with a free design check
Save Concrete. Lower CapEx.
The Engineering Secret: Because our joint transfers weight so efficiently, the structural concrete slab itself doesn't need to be as thick to handle the same load requirements.
The Benefit: Save up to 15% on total concrete volume and excavation work. Get a free custom engineering check to optimize your slab thickness and save direct budget costs.
Highest load transfer in the market
Unmatched Load-Bearing Capacity
Industry Standard: Standard floor joints fail when warehouse loads get too heavy, crumbling under point loads.
The Benefit: Certified structural modeling confirms Cosinus Slide distributes extreme static and dynamic loads better than any other armored joint. It offers massive safety margins.
Placing racks near or on the joint
Total Warehouse Layout Freedom
The Restriction: Normal floor designs require "exclusion zones"—meaning you cannot place heavy storage racks near the joints without cracking the concrete.
The Benefit: Place heavy racks directly on or next to the joint. No structural restrictions mean you can maximize every square foot of your storage space.
Inhouse calculations
Tailored Engineering Design Checks
Our Support: Designing a floor can be complex. You don't have to guess or over-engineer.
The Benefit: Our expert in-house engineers provide full structural calculation reports tailored to your specific project loads and soil quality, giving you fully verified liability safety.
CO2 reduction
Eco-Friendly, Green Construction
The Environmental Impact: Cement production is one of the highest global CO2 producers. Thick concrete slabs heavily impact your project's carbon footprint.
The Benefit: Designing a thinner optimized concrete floor means using significantly less cement. Easily meet BREEAM, LEED, or ESG green-building requirements.
Quick deliveries due to high inhouse stock level
Zero Supply Chain Delays
The Risk: Waiting weeks for essential building materials halts on-site operations and wastes crew budget.
The Benefit: We maintain a massive in-house stock inventory of joint profiles at all times. Get immediate shipping directly to your site, keeping your building schedule on track.
Possibility for on-site support
On-Site Expert Guidance
Our Guarantee: A structural plan is only as good as the physical installation on site.
The Benefit: Our specialized technical consultants can guide your site contractors in person, ensuring flawless alignment and placement before concrete is poured.
High efficiency due to installation tool
Fast, Error-Free Installation
The Manual Hassle: Setting traditional joint profiles manually is slow, labor-intensive, and prone to height errors that ruin floor flatness.
The Benefit: Our custom positioning tools let crews align, secure, and level the joints at record speeds, heavily slashing manual site labor costs.
Less repair costs
Zero Maintenance. Zero Operational Downtime.
The True Cost: Up to 70% of warehouse floor maintenance budgets are spent repairing shattered concrete joint edges.
The Benefit: No broken edges means you completely bypass recurring joint repairs, floor recutting, and costly warehouse shutdowns for decades.
Future-proof building
A High-Value Real Estate Asset
The Future is Automated: Autonomous forklifts (AGVs) and heavy AMRs require extremely flat, vibration-free floors to operate without system sensor trips.
The Benefit: A floor built with Cosinus Slide is immediately ready for next-generation automation, keeping your building highly attractive to premium tenants.
