What Is EPDM + SBR Cast In-Situ Gym Flooring? A Premium Seamless Option for Singapore Gyms
When it comes to building a high-performance gym or sports facility, the type of flooring you choose matters just as much as the equipment. Among the many options available in Singapore, EPDM + SBR cast in-situ flooring stands out as one of the most durable, safe, and seamless flooring systems for both commercial and high-end home gyms.
In this article, we’ll explain what this flooring system is, how it works, and why it may be the best choice for your fitness space.
What Is Cast In-Situ Flooring?
"Cast in-situ" means the flooring is mixed and poured directly on site, creating a seamless and fully bonded surface. Unlike rubber tiles or rolls that require adhesives or interlocking systems, cast in-situ flooring is custom-laid to the shape and size of your gym area.
This allows for:
Seamless surface with no joints
Custom thickness based on usage (e.g. weight zones, cardio zones)
Better durability and hygiene due to lack of seams
Understanding EPDM + SBR Rubber System
This dual-layer system combines two materials:
🔸 SBR Base Layer
Made from recycled rubber granules, usually black.
Provides shock absorption, support, and cushioning.
Can range from 20mm up to 80mm thickness depending on impact requirements.
🔸 EPDM Top Layer
A colored, UV-resistant, EPDM (Ethylene Propylene Diene Monomer) granule surface.
Offers better aesthetics, durability, and anti-slip properties.
Typically 10–15mm in thickness.
Available in many colours or speckled designs.
Benefits of EPDM + SBR Cast In-Situ Flooring
✅ Customizable Thickness & Zones
From light fitness zones to heavy drop areas, the base and top layers can be tailored to match the shock absorption needs of each section.
✅ Seamless and Professional Finish
No more shifting tiles or visible joints. A smooth, uniform surface enhances both aesthetics and safety.
✅ Durability & Impact Resistance
Great for areas with high foot traffic, heavy dumbbells, and fitness machines. The flooring absorbs shock and reduces damage to both equipment and the subfloor.
✅ Anti-Slip and Easy to Clean
The EPDM top layer offers excellent grip even with sweaty feet or shoes, and can be cleaned easily with standard mops.
✅ Noise Reduction
Multi-layered rubber construction helps dampen impact and vibration noise — perfect for high-rise gyms or condominiums with noise restrictions.
✅ Fire Retardant Options
Both SBR and EPDM layers can be treated to meet fire safety standards, especially for commercial builds.
Is It Suitable for My Space?
EPDM + SBR cast in-situ systems are ideal for:
Commercial gyms
Condo & clubhouse fitness rooms
Martial arts studios & MMA gyms
CrossFit boxes & functional training areas
School & institutional gyms
It is not typically used in portable or short-term setups, due to the nature of its permanent installation.
Installation Process (Singapore)
At GymFlooring.sg, our cast in-situ installations follow a strict process:
Site prep & leveling – We ensure the subfloor is properly prepared, often using self-levelling compound.
Mixing & pouring SBR base – Mixed with PU binder and laid to precise thickness.
Curing – Letting the base set properly for bonding.
Laying EPDM top layer – Applied with exacting finish and design pattern.
Final inspection & cleanup
Depending on the area size, thickness, and curing time, the full install may take 3–7 days.
Cost Consideration in Singapore
Pricing depends on thickness, design, and worksite conditions (e.g. access, working hours). As a rough guide:
Base SBR (e.g. 10–80mm) + Top EPDM (10–15mm)
Premium jobs with fire rating, coloured patterns, or restricted access may be higher.
