Wet Pour Rubber Specification

Wet pour rubber specification is used by architects when specifying. Wet Pour rubber  is a popular flooring in playground and play area’s  in schools, nurseries and park. Wet pour can also be used a paving surface in golf courses and retirement homes. The bright colours and impact absorbing properties means it is often specified for new playgrounds . Although the specification is slightly different for each application a general specification can be used.

New Base Work For Rubber Flooring

Where new base works are to be undertaken, account should be taken of local prevailing conditions such as existing drainage and any problems, run off from existing and proposed  surrounding building and canopies.

Minimum Requirements

Excavation to a depth of 100 mm plus the thickness of the required surface. A compacted MOT Type 1 aggregate laid to a thickness of 100 mm. Local deviation of the compacted surface should be no greater than 10 mm under a 3 m length.

Pre Cast concrete edging 150 mm by 50 mm bedded and haunched on concrete is preferred.

The concrete should be set above the compacted stone base, level with the top edge of the wet pour rubber.

The minimum thickness of wet pour rubber which can be laid to a compacted aggregate base is 40 mm.

The thickness  of wet pour rubber flooring required will be dependent on the required critical fall height for any fixed play equipment.

Exisiting Hard Surface For Application of Wet Pour Rubber

Wet pour rubber can be laid onto an existing hard surface such as tarmacadam and concrete and paving slabs. No guarantees can be offered to the longevity of an existing base.

The existing surface should be in good condition and not breaking down i.e. breaking away, crumbling. It must be clean and free from debris such as leaf, moss and algae.

If the existing surface is non porous, drainage holes should be pre-drilled into the surface.

Minimum depth of wet pour which may be laid on to a hard surface is 20 mm. The thickness required will be dependent upon the required critical fall height for any fixed play equipment.

New Hard Surface

Minimum depth of wet pour which may be laid on to a hard surface is 20 mm. The thickness required will be dependent upon the required critical fall height for any fixed play equipment.

Where new macadam is being laid it should have a minimum thickness of 50 mm using aggregate of 10 mm nominal size.

The flooring must be completed a minimum of 14 days before installation of wet pour rubber surfacing.
