EDPM Rubber Wetpour

Wetpour surfacing is made up of a spongy impact-absorbing rubber, which is often described as resembling “squashy rubber tarmac”. It is made by mixing rubber EPDM granules with polyurethane resin which binds it together. It’s a hard-wearing and low-maintenance surface with great versatility.

When to use rubber wetpour?

EDPM rubber wetpour surfacing is a great way to add vibrancy to a playground. It’s available in a variety of colours, which can be combined into imaginative shapes and designs, even incorporating logos and patterns. 

Rubber wetpour is an impact-attenuating surface, designed to minimise the risks of injury as a result of a fall from play equipment. It’s also resistant to abrasion, slipping and ignition.

This makes rubber wetpour an ideal choice for:

  • Incorporating certain colours or branding into a playground design
  • Heavy footfall areas, such as public parks and school playgrounds
  • Laying over existing tarmac or concrete, subject to an inspection

Wetpour installation

Wetpour can be laid directly onto tarmac or concrete, and even on top of previously installed safety surfaces. We would need to check the quality of the existing surface to ensure it is safe to do so, but this can be a cost-efficient way to refurbish an existing play area. Alternatively, wetpour can be laid onto an MOT sub-base. 

The required thickness of the surfacing will depend on the Critical Fall Height (CFH) of the play equipment installed. It can range from 20mm thickness (for 0.6m CFH) to 130mm thickness (for 3.0m CFH). We can advise you on the correct depth for your specific playground project as part of our design or maintenance service consultation. 

All installations of wetpour as a safety surface comply with BSEN1177 standards, and are laid on-site by our fully qualified, enhanced DBS-checked installation team.


EPDM rubber wetpour is very low-maintenance and highly durable. It’s also very easy to repair should the need arise. 

To ensure the ongoing safety of your playground, all equipment and surfacing requires an annual inspection, carried out by an RPII Certified Annual Inspector, as well as regular operational inspections. Learn more about our inspection and maintenance services


The cost of your rubber wetpour surface will depend on the square footage of the play area, as well as the minimum depth required for your playground’s maximum Critical Fall Height (CFH). We can calculate this for you as part of our design or maintenance service consultation.

Yes, our rubber wetpour surfaces are porous, so water can freely drain through them. This should mean that the surface can still be used in wet weather, although this may be dependent on the sub-base or surface underneath the wetpour. Contact us if you’re unsure.

A sub-base is a layer of material used as a stable foundation for the paving or surfacing laid over the top. It provides strength and load-bearing capability for the surface you’re using.

MOT stands for Ministry of Transport; MOT sub-bases are those approved for use for  highways, driveways, car parks and footpaths. We can make sure you have the right sub-base for your chosen surfacing, so if you’re not sure, get in touch.
