Colored EPDM rubber granules are the standard surface layer material in wet-pour and spraycoat sports surfacing systems. The H12 grade is produced for outdoor applications where color stability, surface performance, and long-term weather resistance are primary specification requirements.
EPDM granules are used across running tracks, playground safety surfaces, sports courts, park pathways, and equestrian arenas. The material is compatible with polyurethane binder systems and integrates into both wet-pour and spraycoat installation methods, which covers the majority of outdoor rubber surfacing project types.
The H12 grade is suited to contractors, facility developers, and distributors sourcing consistent, factory-produced granules at wholesale volume. Color availability extends beyond standard options to include custom color matching for projects with defined design specifications.

EPDM rubber resists UV degradation due to the saturated carbon backbone in its polymer structure. In surface layer applications, granules are permanently exposed to direct sunlight. The H12 grade maintains color integrity across prolonged outdoor exposure without significant fading or surface breakdown.
This is the primary reason EPDM is specified over SBR or recycled rubber in visible surface layers. For facilities where surface color is part of the design or branding requirement, consistent color retention over time reduces maintenance and resurfacing costs.
EPDM performs reliably across a wide temperature range. The material does not become brittle in cold climates or lose structural cohesion in high-heat environments. Resistance to moisture, rain, and freeze-thaw cycling keeps the bonded granule matrix stable across seasonal changes.
For outdoor sports facilities operating year-round in variable climates, this reduces the risk of surface layer failure caused by thermal stress or water ingress.
EPDM granules provide the cushioning layer in wet-pour systems. The elasticity of the rubber absorbs impact energy on contact, which reduces injury risk on playground surfaces and provides consistent underfoot comfort on running tracks and courts.
This characteristic is why EPDM is the material of choice for children's playground surfacing and athletic surfaces where fall attenuation or runner comfort is a specified design requirement.
The rubber retains elasticity over time without significant hardening. Surfaces made with EPDM granules maintain their performance feel across years of use, which matters on running tracks and courts where surface response consistency affects athletic output and user safety.
High elasticity also supports even distribution of impact forces across the surface layer, which is a structural benefit in both safety surfacing and high-traffic recreational applications.
H12 is available across a broad range of standard colors. Custom color matching is available where project specifications require it. This allows surface designers and facility managers to integrate color zoning, branding, or decorative patterns directly into the surfacing system rather than relying on paint or overlay treatments.
Consistent color production across batches supports uniform appearance on large surface areas and on projects installed in multiple phases.
H12 granules are compatible with both wet-pour and spraycoat PU binder systems. The granule surface bonds effectively with polyurethane binders during curing, producing a cohesive, durable surface matrix. Compatibility across both system types gives contractors flexibility in installation method selection based on project specification and site conditions.
EPDM rubber granules are specified as the surface or full-depth layer across a range of outdoor projects:
Running Tracks — Surface layer on synthetic athletics tracks. Provides consistent texture, weather resistance, and underfoot feel across the full track surface.
Children's Playgrounds — Safety surfacing around play equipment. The impact-absorbing layer reduces fall injury risk. Color options support multi-zone play area layouts.
Sports Courts — Multi-use courts, basketball surfaces, and tennis surrounds. Color flexibility allows functional zoning and court markings to be integrated into the surface layer itself.
Public Parks and Pathways — Recreational walking paths and outdoor fitness areas. EPDM surfacing provides durable, low-maintenance coverage suitable for sustained foot traffic.
Artificial Turf Systems — EPDM granules are used as infill material in artificial turf installations where colored or non-black infill is required.
Pool Surrounds — Slip-resistant surface around pool decks and splash zones. Weather resistance and moisture compatibility make EPDM appropriate for permanent wet-area installations.
Equestrian Arenas — Arena footing and stable surfaces. Elasticity and drainage compatibility support consistent underfoot conditions.
General Recreational Facilities — Outdoor gyms, skate parks, and community recreation areas requiring durable rubber surfacing.
SBR granules are produced from recycled tire rubber and are available only in black or dark tones. They are commonly used in base layers or as a lower-cost full-depth option. EPDM is manufactured from virgin rubber and is available across a full color range with significantly better UV and color stability. For surface layers requiring color, EPDM is the standard specification. The two materials are frequently combined in two-layer systems, with SBR in the base and EPDM on the wear surface.
Yes. H12 granules are compatible with both wet-pour and spraycoat PU binder systems. The appropriate system depends on project specification, surface design, and installer preference. We can advise on binder selection if required.
Yes. Standard colors are held in production stock. Custom color matching is available for projects with defined color requirements. Feasibility and lead times for custom colors depend on volume and specification. Contact us to discuss custom color requirements before project scheduling.
