EPDM Wet Pour Flooring System for Playgrounds, Sports Areas, Paths & Resilient Outdoor Surfaces
Sport Floor manufactures and supplies EPDM Wet Pour Flooring System materials for seamless resilient surfaces built from compatible rubber granules and polyurethane binder, with single-layer or two-layer configurations selected according to project use.
For many two-layer systems, a resilient SBR or recycled-rubber base provides the lower shock-absorbing layer, while colored EPDM granules form the exposed wearing surface above. Both layers are mixed with compatible polyurethane binder and installed in situ.
Sport Floor manufactures its own polyurethane sports-flooring materials and supplies EPDM and rubber components for complete projects and international orders. German raw materials are used within applicable Sport Floor PU binder formulations, creating a strong technical and commercial route for contractors, playground specialists, landscape contractors, distributors and importers.

What is EPDM wet-pour flooring?
A seamless surface created by mixing rubber granules with polyurethane binder and installing them on site
Wet-pour flooring is installed in situ rather than delivered as factory-made tiles or rolls. Rubber granules are mixed with a compatible PU binder, placed over the prepared base, compacted and finished as a continuous resilient surface.
In a common two-layer construction, the lower layer uses SBR or compatible recycled rubber to provide resilient depth, while the upper layer uses colored EPDM granules to create the visible wearing surface and project design.
Single-layer EPDM systems can also be used where the project does not require a separate shock-absorbing base. The correct build-up should be determined by application, expected loading, safety requirement, drainage and the selected technical specification.
Seamless in-situ installation without tile joints across the main surface.
Two-layer systems separate resilient SBR base function from colored EPDM wearing function.
Single-layer EPDM can suit applications where a dedicated lower impact layer is not required.
Granule size, binder ratio and thickness remain system-specific.

Typical two-layer build-up
Prepared base → resilient SBR layer → colored EPDM wearing layer
SBR Resilient Layer
Selected SBR or rubber granules mixed with compatible PU binder form the lower resilient zone where required.
EPDM Wearing Layer
Colored EPDM granules mixed with compatible binder create the exposed decorative and functional surface.
Project-Specific Finish
Final texture, colors, patterns and detailing are selected around the project and current system data.
Wet-pour application control
Good wet pour depends on binder compatibility, uniform mixing, compaction and finishing
The polyurethane binder must wet and connect the granules sufficiently to create a coherent resilient layer. Rubber type, particle shape, granule size and climatic conditions can change binder demand, so a generic ratio should not be copied from another manufacturer's system.
Uniform mixing is equally important. Poor binder distribution can create weak areas, loose granules or inconsistent appearance. Placement and compaction should be controlled to create an even layer without overworking the surface.
For the exposed EPDM layer, the installer must also control color distribution, joints between design zones and finishing quality. Exact binder ratio, consumption, granule size, working time and curing should follow current Sport Floor technical documentation.
Do not copy competitor binder ratiosRubber type, granule size, layer depth, climate and binder formulation all affect the correct material quantity.
Select the right wet-pour system
Single-layer EPDM, two-layer SBR + EPDM and playground safety systems answer different project needs
Single-layer EPDM: suitable where the exposed colored EPDM surface is required but a separate shock-absorbing base layer is not part of the specification.
Two-layer SBR + EPDM: separates resilience and aesthetics. The lower SBR/rubber layer creates resilient depth, while the upper EPDM layer provides the exposed colored wearing surface.
Playground safety flooring: the lower resilient depth is selected around the required tested impact performance and equipment fall conditions. A generic thickness should never be assumed from another project.
Important: if the project requires EN 1177, HIC or critical-fall-height performance, only use current system-specific test evidence for the exact build-up being offered.

Binder selection
Aromatic and aliphatic binder routes serve different exposure and color priorities
| Selection point | Aromatic PU binder route | Aliphatic / UV-stable binder route |
|---|---|---|
| Typical commercial role | Common binder route for resilient rubber layers and compatible applications. | Selected where greater color/UV stability is required in the exposed surface system. |
| Where it may fit | SBR base layers and project-specific EPDM applications. | Exposed colored EPDM layer where the selected system calls for this binder type. |
| Color considerations | Exact visible effect depends on formulation and exposure. | Designed around improved color stability in suitable applications. |
| Sport Floor product | PU Binder Aromatic | PU Binder Aliphatic UV Resistant |
| Final selection | Use current Sport Floor TDS and project requirements for the actual binder supplied. | |
Drainage & base design
Water-permeable wet pour still needs a complete drainage route beneath the surface
A permeable surface does not make poor civil construction disappear. Water passing through the rubber layers still needs somewhere to go. The sub-base, gradients, drainage and perimeter detailing should therefore be designed with the selected system.
Permeable Base Route
Where the full construction is designed to drain vertically, the supporting base should allow the water-management strategy to continue below the wet-pour surface.
Impermeable Base Route
Concrete or other impermeable bases require suitable falls, drains or edge detailing so water does not remain trapped.
Avoid Standing Water
Surface levels, drainage outlets and finished transitions should be resolved before rubber installation begins.

Installation workflow
From prepared base to finished colored EPDM surface
Inspect Base & Drainage
Confirm stability, levels, falls, drainage route and compatibility before rubber work begins.
Install SBR Base
Where required, mix the selected rubber granules with compatible PU binder and install the resilient lower layer.
Install EPDM Layer
Mix colored EPDM with the selected binder, place uniformly and finish the exposed wearing surface.
Cure & Inspect
Protect the new surface from traffic and contamination until the applicable curing requirement is satisfied.
Common specification mistakes
Wet-pour quality drops quickly when one layer is treated as a generic commodity
Generic Binder Ratio
Do not use another supplier's binder percentage for a different granule or formulation.
Wrong Binder for Exposure
The exposed EPDM layer and hidden SBR base may have different binder-selection priorities.
Ignoring Drainage
A permeable rubber surface still requires a functional route for water below and around it.
Choosing Playground Thickness by Guess
Safety-oriented thickness should be linked to the actual tested project requirement.
Poor Granule Mixing
Uneven binder distribution can create weak zones and inconsistent appearance.
Confusing Wet Pour with Tiles
Wet pour is an in-situ seamless installation, not a prefabricated modular rubber product.
