Soft Play Wet

Pour Rubber Safety Surfaces

Wet Pour Rubber Surfaces can be laid on top of most existing well-drained hard surfaces with a ramp edge. Alternatively, it can be installed directly in to a newly prepared excavated base so that the wet pour finishes flush with surrounding ground levels. Whilst it is more expensive to excavate a base, we recommend that wherever possible all rubber surfacing is laid flush to the ground level.

Oexisting hard bases

Wet Pour Rubber Surfaces can be laid on top of an existing base such as concrete, bitmac or asphalt which should be firm and even. To avoid any problems, reference should be made to the contractor for approval of the suitability of the existing base. A chase should be cut at the perimeter of the area to assist bonding and the wet pour should be gently ramped at the edges to reduce a potential trip point and accommodate the change in level. It should be noted that this ramp can create an access problem for wheelchair users.

Onew excavated bases

Where new excavated bases are being constructed either a purpose-laid loose stone foundation or concrete sub-base should be laid.

Oaggregate base

If an aggregate is used it should be crushed rock graded to MoT Type 1 classification, compacted and regulated to a finished thickness to suit site conditions, usually ranging from 100mm to 300mm deep. This foundation layer should be laid with local deviations no greater than 10mm under a 3m straight edge in any direction.


Ono-fines base

This alternative material consists only of cement, clean course aggregate (usually washed gravel or clean crushed rock) and water to a recommended mix of 4 parts aggregate: 1 part cement. Fine aggregate (sand) is omitted leaving a cellular structure through which water can drain. Where only pedestrian traffic is expected a single 75mm thick layer will usually be thick enough. After spreading, screeding and hand trowelling, the concrete should be compacted. Tolerance of ±6mm in general level are required.

After compaction, the concrete should be protected from rain damage or rapid drying. Bay sizes should be restricted to a maximum of 5m square. Areas larger than this should include expansion joints. No-fines concrete surfaces should be completed at least 14 days before wet pour is installed.

Oinstallation

Since the rubber granules, binders and additives are mixed on site, the installation of the wet pour is undertaken by skilled installation teams nation-wide. The elements are mixed together laid, levelled and rolled.


Operimeter edging

Wet pour which is laid into an excavated base, should be retained by edging. We quote for pre-treated timber edging as standard and pre-cast concrete edging can also be used although this is more expensive. The edging should be installed above the level of the sub-structure by the thickness of wet pour surfacing which is going to be laid.

Oin-situ or wet pour

An “in-situ” or wet pour surface is mixed to controlled specifications on site and is then laid onto an existing concrete or tarmac surface or a new hardcore base. Varying depths of wet pour (which have different Critical Fall Heights) can be laid across a site to meet the Potential Fall Height requirements of equipment of different heights. The SSP Wet Pour rubber system utilises top quality resins and recycled rubber granules.

Osingle or double layer

The depth of wet pour which is laid depends upon the Potential Fall Height of the surrounding play equipment. The SSP Wet Pour surface is available in a single layer from 15mm to 30mm deep or use around low level or re-locatable equipment on an existing tarmac or concrete base. For higher equipment, the surface is laid in a double layer to a depth of between 40mm and 100mm for both existing or new bases.

Ocolours and graphics

The SSP Wet Pour system is supplied in black as standard although it is available in a range of colours at an extra cost.

Graphics and games can be incorporated into the design of the surface to create an enjoyable and educational play surface.
