Wetpour is a playground surface made of granulated rubber crumb. It is installed as a one or two-layered system, depending on whether play equipment is present on site.

Our highly skilled installation teams can replicate virtually any design, logo or pattern. The surface has passed the most comprehensive testing criteria which include Critical Fall Height, flammability, indentation and abrasive wear.


Installers arrive on site wearing full PPE and sign in if required. Once equipment has been unloaded, installers measure area, take photos, check dips and report temperature.

The area is then dried with a gas lance and cleared of leaves and debris. Edges are primed twice to reduce Wetpour shrinkage.

If a Critical Fall Height is required, the impact absorbing layer is first installed using SBR rubber. Materials are mixed with a resin-binder and transported by wheelbarrow to the area for laying. The mixture of rubber and resin is levelled to the required thickness, and a screed, roller or hand trowel is used to smooth and lightly compact the surface to gain an even, level finish.

Once the SBR layer has cured, the process is repeated using EPDM granules to install a second layer.

Bespoke graphics and designs can be inserted into the EPDM by cutting shapes and filling with alternative relevant colours. Alternatively, Mounds can be installed to the SBR layer.

The surface is ready to use the following day.

Wetpour Case Studies

Build Up


Wetpour is most often installed onto a prepared hard surface, such as stone (MOT) or macadam. The sub-base should be dry, level and compact all over, and any deviations should be such that when a 3m long straight edge is placed in any position on the surface, the gap between the straight edge and the surface shall at no point be greater than +/-6mm.




All Wetpour Surfacing should undergo routine and operational inspection and maintenance in accordance with the recommendations of EN 1176.

The frequency of inspection will vary with the type of equipment used and other factors such as heavy use, levels of vandalism, coastal location, air pollution, age of equipment, location adjacent trees.

If the surface is discovered to be unsafe during inspection and cannot be corrected immediately, the surface should be secured against further use.


Q: What is EPDM?
A: EPDM stands for Ethylene Propylene Diene Monomer (synthetic rubber).

Q: What depth is wetpour laid to?
A: The top layer of the wetpour (wearing course) is laid to a minimum of 15mm. If play equipment is present, a CFH (critical fall height) is measured and the base course is adjusted depending on the amount of impact absorbing protection that is needed.

Q: Where is the rubber and resin sourced from?
A: All rubber is sourced from the UK and western Europe only. This ensures that our products comply with safety standards and are non-toxic.

Q: How soon can the surface be used after installation?
A: We recommend a minimum of 24 hours, especially during winter months when the binder could take longer to cure.

Q: Which edges should be used when installing wetpour?
A: We recommend pre-cast concrete or rubber edges are installed to ensure that the contraction and expansion of rubber, due to temperature changes in the weather, does not cause gaps between the edge and the surface.

Q: Can wetpour be installed onto steps?
A: Wetpour can be installed onto steps, as long as there is an edge for it to be installed up to.
