Why a Moisture Barrier is Essential for Protecting Your Fuji Tatami and MMA Mats on Concrete Floors
In the world of martial arts training, your flooring is more than just a surface—it's the foundation of safety, performance, and longevity. At Fuji Mats Australia, we know that installing high-quality Tatami or MMA mats on concrete slabs can transform any space into a dojo or gym. But there's a hidden threat lurking beneath: moisture from concrete floors. Without proper protection, rising damp can wreak havoc on your investment. That's where a moisture barrier for tatami mats and MMA flooring comes in. In this guide, we'll explore why it's crucial, spotlight our top two options, and show you how prevention beats cure every time.
The Hidden Dangers of Moisture in Concrete Floors
Concrete slabs are notorious for retaining moisture, especially in Australia's variable climate. Whether you're dealing with a newly poured concrete slab still curing or an older floor hit by heavy rain, water vapour can seep upwards through the porous surface. This rising moisture doesn't just create slippery conditions—it attacks the adhesives and foams in any Tatami or MMA Mats... regardless of brand.
The result? Delamination, where layers of your tatami or MMA mats separate, bubble, or warp. Not only does this compromise footing, grip and cushioning for athletes, but it also shortens the lifespan of your flooring, leading to costly replacements. In humid regions like Queensland or coastal New South Wales, this issue is even more prevalent. By ignoring moisture protection, you're gambling with your training space's durability.
Prevention is the Best Medicine: How a Moisture Barrier Safeguards Your Mats
Enter the moisture barrier for concrete floors—your first line of defence against rising damp. Applying a barrier seals the slab, creating an impermeable layer that stops water vapour from migrating into your mats. This simple step prevents delamination, maintains mat integrity, and ensures a safe, consistent surface for rolls, throws, and strikes and extends the commercial lifespan of your Fuji Mats.
For new installations on freshly poured concrete, a barrier allows the slab to fully cure without trapping moisture underneath. On established floors, it blocks post-rain surges that can push dampness up after a downpour. At Fuji Mats Australia, we recommend integrating this protection during installation to avoid future headaches. It's not just about fixing problems—it's about building a resilient setup from day one.
Discover Our Top Moisture Barriers for Tatami and MMA Mats
We stock premium solutions tailored for Australian conditions, ensuring compatibility with our Fuji tatami and MMA mats. Here are the two standout options:
1. Mapei Planiseal MR Moisture Barrier Sealer
This epoxy-based sealer is a go-to for professional installers. Applied as a liquid coating, it penetrates deep into the concrete, forming a tough, vapour-proof membrane. Ideal for high-traffic gyms, it's quick-drying and ready for mats in as little as 24 hours. Perfect for suppressing moisture in slabs up to 25 lb/1000 sq ft/24 hrs (ASTM F1869).
2. Dunlop Aquacoustic Underlay
For a cushioned approach, this acoustic underlay doubles as a moisture vapour barrier. Made from recycled rubber, it rolls out easily under your mats, absorbing impacts while blocking damp. It's eco-friendly, noise-reducing, and compliant with Australian building standards—great for home dojos or community centres where sound and sustainability matter.
Both products are readily available through Fuji Mats Australia and designed to integrate seamlessly with our flooring range.
