Frequently Asked Questions

Q: Are these 20mm gym mats truly interlocking or do they use a butt-joint system?
A: These tiles use a precision butt-joint system rather than a jigsaw interlocking edge. This means the tiles sit flush against each other with straight edges, creating a seamless, professional finish without raised interlocking borders. This system is preferred in commercial environments for its cleaner appearance and greater stability under heavy loads.

Q: How do I stop the tiles from spreading apart over time without interlocking edges?
A: The butt-joint system remains stable under normal gym use due to the weight of equipment placed on the tiles and the friction between the rubber underside and the subfloor. For permanent installations or areas subject to heavy lateral forces, perimeter tiles can be secured with flooring adhesive to prevent gradual spread.

Q: What load can these 20mm mats support?
A: These tiles are rated to 400kg/m² static load, making them suitable for the heaviest gym equipment including squat racks, functional trainers, weight storage systems, and cardio machines. The high-density rubber composition (1.1–1.3 g/cm³) ensures they do not compress or deform permanently under sustained heavy loads.

Q: What is the coverage per tile and how do I calculate my order quantity?
A: Each tile measures exactly 1000mm × 1000mm, providing 1m² of floor coverage. To calculate your order, measure your gym floor area in square metres. For rooms with irregular shapes or cuts required around equipment bases, add 5–10% to your measured area to account for wastage.

Q: Are these mats suitable for a school or leisure centre as well as a home gym?
A: Yes. The CE marking, REACH compliance, and R10 slip resistance certification make these tiles suitable for both domestic home gym use and commercial environments including school sports halls, leisure centres, and community fitness facilities. The 400kg/m² load rating exceeds the demands of most educational and community fitness applications.

Q: Can I use a partial area of these tiles — for example, just under a squat rack?
A: Yes. You can install these tiles in any area without needing to floor an entire room. Many customers use them to create dedicated lifting platforms, equipment zones, or protection areas under racks and benches. The tiles work equally well as partial floor coverings and can be extended later as your gym grows.
