hoe worden sportschoolrollen gemaakt

High-performance rubber flooring is made by mixing fine rubber powder with specific additives, then feeding this compound into a continuous vulcanization machine (a Rotocure). Under constant, precise heat and pressure, the material is cured into a dense, uniform roll with consistent durability and thickness.

This process, known as rotocuring or continuous vulcanization, is the gold standard for producing premium rubber sheeting and flooring rolls. It differs significantly from basic press molding, where individual tiles are cured one by one. The rotocure machine uses a large, heated steel drum that rotates against a pressure belt. The raw rubber compound is fed into the gap and vulcanizes as it travels around the drum under relentless heat and pressure. This continuous motion ensures that every inch of the flooring receives the exact same treatment, eliminating the inconsistencies in density and curing that can occur in batch-press methods. The result is a perfectly uniform roll, free from weak spots, with superior dimensional stability and a flawless surface finish—qualities essential for a professional and long-lasting gym floor.

This advanced manufacturing process is only effective if the ingredients are of the highest quality. The final product’s performance is ultimately determined by what goes into the mixer.

Why Do the Raw Materials Matter So Much?

The choice of raw materials directly impacts durability, safety, and even ease of cleaning. We use purified, fine-mesh rubber powder instead of coarse granules for higher density, and precisely weighted EPDM particles to guarantee a perfectly uniform color distribution.

The Base: Purified, Fine-Mesh Rubber Powder

The foundation of our flooring is recycled rubber powder. However, not all powder is created equal. We insist on a fine-mesh grind. This creates a much denser, less porous final product compared to flooring made from larger, coarse rubber chunks. For you, this means two things: first, the higher density provides better shock absorption and durability against heavy impacts from weights. Second, the non-porous surface is more hygienic and easier to clean, as it prevents sweat, dirt, and bacteria from penetrating the material. Before any rubber enters our production line, it undergoes a multi-stage screening process to remove textile and metal contaminants, ensuring 100% purity.

The Details: Engineered EPDM and Binders

The colored EPDM flecks that provide the aesthetic are a key area of our engineering focus. A common issue is uneven color, caused by EPDM particles that are too light (and float) or too heavy (and sink) in the rubber mix. Our solution is to precisely formulate our EPDM granules to match the specific gravity of the rubber compound. This ensures they remain perfectly suspended during mixing and curing, resulting in a consistent, professional appearance across the entire floor. This is bound together with a high-performance polyurethane adhesive that ensures exceptional tear strength and elasticity, preventing cracking or granule loss over years of heavy use.

A premium product can be ruined by poor execution. Let’s talk about standards.

What Quality and Safety Standards Are Non-Negotiable?

For any gym flooring, CE and REACH certifications are the baseline for safety, confirming compliance with EU health standards. For commercial spaces, a fire safety rating of Cfl-s1 (EN 13501-1) is a non-negotiable legal and safety requirement.

Health and Environmental Safety

Your clients’ health is paramount. That’s why REACH compliance is so important. It is a rigorous EU regulation that guarantees our flooring is free from a long list of harmful chemicals. This means no dangerous off-gassing and complete safety during exercises involving floor contact. The CE mark is a broader declaration that our product adheres to all relevant EU legislation, acting as your assurance of its overall safety and quality.

Building and User Safety

For any public or commercial space, fire safety is a legal matter. Our flooring meets the strict Cfl-s1 classification under the European standard EN 13501-1. This is a critical feature that your building inspector will look for. Furthermore, user safety is enhanced by our certified slip resistance (R9-R10). This provides the necessary grip to prevent accidents during intense workouts, protecting both your clients and your business from liability. These are not just quality marks; they are essential components of a responsible and professional fitness facility.

Even with the best materials and certifications, a poor installation can lead to failure.

How Can Installation Undermine a High-Quality Floor?

The most common installation failure is improper subfloor preparation. The ground must be perfectly clean, dry, and level. For rubber rolls, using anything less than a full-spread application of a polyurethane adhesive will lead to bubbles and lifting edges over time.

The Foundation: Subfloor and Acclimatization

You can have the best flooring in the world, but if the subfloor is dirty, damp, or uneven, the installation will fail. The adhesive will not bond correctly, leading to bubbles and peeling. Before we even unroll the product, the concrete must be professionally cleaned and confirmed to be dry. Just as important is acclimatization. The rubber rolls must be left unrolled in the installation room for at least 24-48 hours to adjust to the ambient temperature and humidity. Skipping this causes the material to expand or shrink after it’s been glued down, creating unsightly gaps or buckles.

The Execution: Adhesion and Pressure

For rubber rolls, a "full-spread" adhesive application is the only correct method. This means covering 100% of the subfloor with a quality, two-part polyurethane adhesive. Spot-gluing to save money will inevitably lead to failure. After laying the roll into the adhesive, the most critical finishing step is to use a heavy, 50kg (110lb) weighted floor roller. This tool is essential to press out any trapped air and ensure a complete, permanent bond between the flooring and the subfloor. This step guarantees a truly seamless and stable surface built to withstand years of abuse.

Conclusie

A superior gym floor is the result of a rigorous system: pure, fine-grained materials, an advanced continuous vulcanization process, and adherence to strict safety standards.
