Bagaimana cara memilih ketebalan lantai gym karet yang tepat untuk studio kebugaran?

The correct thickness is determined by the impact load of each specific zone. Use 10mm or thicker for heavy weight-drop areas to prevent subfloor damage. Use 8mm for general functional training, and 6mm is sufficient for cardio machine areas and walkways. Thickness must be paired with the correct density.

As a production manager, I don’t write marketing copy. I oversee the vulcanization presses and the raw material mixes that determine a floor’s real-world performance. The most common and costly mistake I see facility owners make is equating thickness with protection. The truth is, thickness is only half of the equation. The other, more critical half is density. An investment in the wrong flooring can lead to cracked concrete subfloors—a catastrophic failure—or a floor that wears out years ahead of schedule. This guide will walk you through how to make an engineered decision, matching the material science to the physical demands of your studio.

Before you choose a product, you need to understand the fundamental physics at play. Let’s look at why a thicker floor isn’t automatically the superior choice.

Why is a thicker floor not always the better floor?

Density (kg/m³), not just thickness, dictates performance. A very thick but low-density floor can fail to distribute impact force effectively. A moderately thick, high-density floor often provides superior protection against subfloor cracking and has better acoustic properties.

Think of it this way: a 4-inch thick block of styrofoam is much thicker than a 1-inch thick slab of solid oak, but which would you rather have under a dropped 100kg barbell? The oak’s density distributes the force over a wider area, protecting what’s underneath. It’s the same principle with rubber flooring. On our spec sheet, you’ll see our 20mm composite tiles have a density of 833 kg/m³, while our 10mm rolls are much denser at 1050-1100 kg/m³.

This has two major implications. First, for blunt force trauma (a heavy, accidental drop), the sheer thickness of the 20mm tile provides more material to absorb the initial impact. Second, for vibration and acoustics, the high density of the 10mm roll is far more effective at deadening sound—our data shows it provides sound improvement of Ln,w < 50 dB. This is a critical specification if your gym has neighbors or is on an upper floor. We also engineer for a Shore A hardness of 65±5. This ensures the floor is firm enough for stable footing during heavy lifts but has enough elasticity to absorb energy and reduce joint stress.

Understanding this interplay between thickness and density is crucial. Now, you can apply this knowledge to create a precise flooring plan for your facility.

How do I map floor specs to specific gym zones?

Analyze each zone by its primary risk factor—impact, vibration, or traffic. Then, match the technical specifications to mitigate that risk. This data-driven approach optimizes protection and budget, preventing over-specifying in low-risk areas and under-specifying where it matters most.

Zone 1: Free Weight and Deadlifting Areas

The only goal here is to prevent subfloor damage from heavy, uncontrolled drops. This requires maximum energy absorption. The 20mm or 25mm composite tiles are the correct engineering choice. Their thickness provides the necessary cushion, while their 833 kg/m³ density is sufficient to begin distributing the load. Anything less than 10mm in this area is a serious risk to your building’s structure.

Zone 2: Functional Training and Group Fitness

This zone is about durability against a wide range of movements. Kettlebells get dropped, sleds are pushed, and there is constant, dynamic footwork. Here, density and tensile strength are more important than sheer thickness. The 8mm roll, with its high density (1050-1100 kg/m³) and robust tensile strength (2.6 MPa), is ideal. It resists abrasion and tearing while its density provides excellent acoustic dampening and just enough shock absorption to protect joints without feeling "spongy."

Zone 3: Cardio and Fixed-Machine Areas

The load here is static but heavy. The risk is long-term indentation and vibration. A 6mm or 8mm high-density roll is more than adequate. Its dense structure will support the weight of heavy treadmills and strength machines without compressing over time. It also effectively dampens machine vibrations, creating a quieter environment. Using a 15mm tile here would be a waste of material and money.

With the right product specified for each zone, the final consideration is the installation format. This choice has practical consequences for installation and long-term maintenance.

What are the real-world trade-offs between tiles and rolls?

Tiles offer supreme ease of maintenance for high-impact zones, as a single damaged unit can be replaced. Rolls offer a more hygienic, seamless finish for large areas but require more labor-intensive installation. The choice is a trade-off between installation cost and long-term repair flexibility.

From the factory, I see both products being made to the same quality standards, but their form factor dictates their best use. Interlocking tiles are brilliant for a deadlifting area because when—not if—someone damages the floor by dropping a sharp-edged plate, you are only one replacement tile away from a perfect floor. Their installation is also more forgiving on a subfloor that isn’t perfectly level.

Rolls, on the other hand, are the superior choice for large cardio and functional training areas. While the installation is more demanding due to their weight (an 8mm roll weighs 8.8 kg per linear meter), the result is a nearly seamless surface. This is a significant advantage for cleaning and overall hygiene. Fewer seams mean fewer places for sweat, chalk, and dirt to get trapped. The decision comes down to this: do you want to optimize for ease of repair (tiles) or for a seamless, easy-to-clean surface (rolls)?

Your flooring choice is an integral part of your facility’s engineering. Make the decision based on data.

Kesimpulan

Make an engineered decision for your gym floor. Match the material science—specifically thickness and density—to the physical demands of each zone. This ensures maximum safety, durability, and return on investment.
