Industrial concrete floors are put through a lot every day. Forklifts, vehicles, and heavy traffic place significant strain on joints and floor surfaces. A quick and durable repair is therefore crucial. With three new repair kits, Hengelhoef Concrete Joints has been addressing various types of floor damage since April 1, 2026. Tom Robyns, commercial manager for the Benelux, explains the approach and the vision behind it.
Hengelhoef Concrete Joints (HCJ) has been focusing on solutions for joints in industrial concrete floors for years. “It’s not just about reinforcing a joint, but also about preventing damage and extending the service life of the entire floor,” says Robyns. “That vision aligns with the development of the Cosinus Slide® solution in 2007 and the Cosinus floor concept in 2012. With the latter, we moved away from traditional anchoring. The guiding principle: ‘the joint is the floor, the floor is the joint.’”
“Since April 1, 2026, we have been complementing that philosophy with three concrete solutions. Each system is tailored to a specific type of repair: a structural repair across the full depth of the floor, a partial surface repair, or the connection of a new floor to an existing one.”
The first solution is the full-depth repair kit, designed for floor damage that extends across the entire thickness of the concrete floor. “The damaged floor is completely cut out along its length, width, and depth, down to the subgrade,” says Robyns.
“At HCJ, we then provide the customer with a pre-calculated complete package containing all the necessary components. This includes, among other things, joint profiles, rebar and rebar mesh, shrink-free repair mortar, and chemical anchors. We deliver the complete set of materials on a pallet to the job site, including installation instructions. Our approach is unique because the customer receives exactly what is needed for the specific repair.”
“All parts are pre-calibrated and tested. As a result, the components are perfectly compatible with one another, which should extend the service life of the repaired joint. In addition, we offer a five-year warranty on our products. And if you need extra assistance, you can take advantage of our ‘Support On Site’ service, through which we collaborate with independent local subcontractors in the Benelux.”
Not every instance of damage requires a complete replacement of the floor panel. That’s why the Surface Repair Kit is available for superficial damage. Robyns: “We also launched this kit in early April. It’s designed for repairs at a partial depth of 40 to 100 millimeters.”
“The existing substrate will be preserved, while the damaged upper concrete layer will be repaired. The kit includes joint profiles, chemical anchors, a reinforcing mesh, and high-strength repair mortar. With this, we aim to provide a quick and efficient solution for damage that does not extend through the entire depth of the floor.”
The third newcomer, Cosinus Connect, is not a repair kit for a damaged floor in the traditional sense. The solution is intended for situations where a new industrial floor needs to be connected to an existing floor.
“A special joint with a connecting plate provides the connection between the two concrete floors,” Robyns explains. “We designed this kit to ensure continuous load transfer and a shock- and vibration-free transition. Once again, we supply all the necessary components, including threaded rods, nuts, the joint profile, and non-shrink mortar. This way, the customer receives a pre-assembled system rather than separate products that still need to be coordinated on-site.”
According to Robyns, this comprehensive approach offers significant added value. “The customer no longer has to source all the components themselves and figure out how to combine them. HCJ calculates what’s needed in advance and delivers the complete package to the job site.”
“Our customers” initial experiences have been very positive. The parts are pre-matched, the shipment arrives ready to use in the correct quantities, and this makes the repair easier to carry out.”
