Is Rubber Flooring Waterproof for Gyms and Outdoor Use?
Rubber flooring is popular in gyms and outdoor areas — but is it truly waterproof?
Yes, rubber flooring is generally water-resistant, but not completely waterproof. The degree of water resistance depends on the product type and installation method.
Even if you’re installing rubber flooring in wet areas, understanding the difference between water-resistant and waterproof is key to choosing the right product. At Lanhefloor, we offer both indoor and outdoor rubber flooring options built with moisture protection in mind.
What makes rubber flooring water-resistant?
Rubber’s natural properties help it resist moisture, but installation and product composition make the biggest difference.
Rubber flooring resists water thanks to its dense, non-porous structure, but it still has seams and edges that can let water through if not sealed properly.
How rubber repels moisture
Rubber itself doesn’t absorb water. Especially products made from SBR (Styrene-Butadiene Rubber) or EPDM (Ethylene Propylene Diene Monomer) have excellent water resistance. You can explore our different options like Tiny Granule Rubber Tile or Composite Gym Rubber Tile to learn more.
| Material | Water Resistance | Notes |
|---|---|---|
| SBR Rubber | High | Common in gym tiles and rolls |
| EPDM Rubber | Very High | Ideal for outdoor and wet areas |
| Composite Tiles | High | If surface is EPDM laminated |
That said, tiles and rolls have seams. Without sealing, water can seep through those gaps. That’s why glued-down installations with sealed seams are more water-resistant than loose-laid ones.
Different zones, different risks
Rubber tiles are thick and durable, often used in weight zones. Rolls are smoother and better for yoga or cardio. Rolls may resist moisture more evenly due to fewer seams, but both can perform well in humid or spill-prone spaces if installed right. You can see more about our gym rubber rolls or interlocking puzzle tiles for flexible setups.
Is gym rubber flooring waterproof enough for indoor use?
Yes, gym rubber flooring is water-resistant enough for indoor use in high-humidity areas, provided installation is done correctly.
For gyms, water resistance comes from both the material and proper installation techniques.
Understanding indoor application limits
Gym floors experience sweat, water bottle spills, and cleaning solutions. According to our catalog, both rubber tiles and rubber rolls are designed to handle these situations. However, standing water can still cause mold or mildew if it seeps into unsealed joints.
| Product | Suitable for Wet Area? | Notes |
|---|---|---|
| Rubber Tiles | Yes (with sealed edges) | Best for heavy use zones |
| Rubber Rolls | Yes | Fewer seams, easy to clean |
| Interlocking Tiles | Caution | May allow water through seams |
Key Installation Tip
Use adhesives and seam sealers in areas where water contact is frequent. Always make sure subfloors are dry before installation to avoid trapping moisture underneath.
Can outdoor rubber flooring handle rain?
Yes, outdoor rubber flooring like EPDM surfaces are designed to handle rain, UV, and temperature changes.
Lanhefloor’s outdoor rubber flooring series is weather-resistant and safe for wet environments like playgrounds and parks.
Rain, sun, and temperature — no problem
Outdoor rubber floors, especially those using EPDM granules, are built to last outside. These products are non-slip, UV-stable, and designed to stay intact despite rain or sun exposure.
| Feature | Outdoor Tile | EPDM Wetpour |
|---|---|---|
| Rainproof | ✅ | ✅ |
| UV Resistant | ✅ | ✅ |
| Drainage Needed | Optional | Recommended |
| Installation | Glue or loose lay | Poured in place |
Tiles like hexagon, square, and bone-shaped interlock well to keep surfaces secure and minimize water pooling. For visual references, browse our project gallery to see how they perform in real-world use.
Are there any limitations to rubber flooring’s waterproofing?
Yes. Rubber flooring is not suitable for submerged or soaking-wet conditions unless extra waterproofing measures are added.
Even though rubber doesn’t absorb water, water can seep through seams, corners, or under the floor if not sealed.
When "water-resistant" isn’t enough
In locker rooms, pool decks, or commercial kitchens, you need more than basic resistance. Seamless flooring like vinyl or poured-in-place rubber with waterproof membranes might be better in those cases.
Watch out for:
- Improper installation: Gaps between tiles or bad sealing can let water through.
- Water under flooring: If water gets trapped beneath, it can lead to mold.
- Cleaning: Avoid excessive water. Use damp mops instead of flooding.
To make your rubber floor more waterproof:
- Use adhesive installation.
- Seal seams with appropriate fillers.
- Ensure subfloor is smooth and sealed.

Conclusion
Rubber flooring is water-resistant and safe for gyms and outdoors, but not completely waterproof without sealed installation.
