What is it !

Wet Pour rubber safety surfacing is suitable for playground installations where impact absorbent surfacing is a requirement up to the appropriate Maximum Free Fall Height (see chart below). It can be used around complex configurations of playground equipment and ground contours.

Wet Pour surfacing for playgrounds is slip-resistant and non-abrasive to young children. It is porous, so no puddles.

Colourful graphics can be created within the Wet Pour for games or emblems. This is done by designing a stencil and cutting out the top layer colour to replace it with contrasting colours.

How it Works !


1) Solid sub base & border is required
2) It is pourous
3) Mix and lay base crumb (10% resin)
4) Mix and lay EPDM top (20% resin)
5) Allow 12 hours for each layer to cure

The required sub bases for wetpour

  1. Concrete or open-textured tarmac
  2. MOT Type 1 stone (50mm or more)

The Standard Wetpour Method
(2 layer process)

The base layer provides the safety cushion effect. It is recycled 2-6mm crumb bonded rubber, mixed on site using special equipment and laid to exacting standards usually 30-50mm with 10% resin. It is relatively cheap costing about £14 per square metre at 30mm (£4.5 per 10mm approx) .

Base layer per 1m 2-6mm crumb Resin
20mm depth 12.5 kg 1.25 kg
25mm depth 15.6 kg 1.56 kg
30mm depth 18.15 kg 1.82 kg
35mm depth 18.75 kg 1.88 kg
40mm depth 25 kg 2.5 kg

The top EPDM layer. Recommeded to be 20mm it is a specifically manufactured polymer of  1-4mm granules designed to be very hard wearing and colourfull. It is more expensive at about £45 per square metre depending upon which colour.

15mm depth 12.5 kg 2.5 kg
20mm depth 16.7 kg 1.7 kg
25mm depth 20.1 kg 2.0 kg
