How Much Fall-Height Protection Does Rubber Wet Pour Offer?

Choosing the right surfacing for school playgrounds is a critical safety decision. At LawnKing, serving clients across Randburg, Midrand, and beyond, we understand how serious this is. That’s why many of our artificial grass playground installations incorporate rubber wet pour or shock-absorbing underlayers to comply with fall-height safety standards. In this post, we’ll unpack what fall-height protection rubber wet pour provides, why it matters, and how LawnKing integrates these systems.

Why Fall-Height Protection Matters for School Playgrounds

Falls are one of the most common causes of playground injuries. When children climb, jump, or swing, the risk of dropping from a height is very real. If the surface beneath that equipment is hard — like concrete or compacted earth — the potential for serious injury increases dramatically. Rubber surfacing provides an essential safety buffer.

In South Africa, the SANS 51177 standard determines the necessary impact protection for playground surfaces. This standard mirrors the international norm EN 1177, and sets out “critical fall height” criteria — essentially, the maximum height from which a child can fall without sustaining a serious injury.

How Rubber Wet Pour Works to Absorb Impact

Wet pour rubber surfacing is made by mixing rubber granules (often recycled) with a polyurethane binder. It is applied on-site in two or more layers. The base layer (usually coarser granules) provides the cushioning, while the top layer (finer granules, often coloured) forms a smooth, durable wear surface.

Because the rubber is poured in place, the surface is seamless. That means no gaps, no trip hazards, and very good shock absorption across the entire area.

Importantly, the thickness of the wet pour layer is directly related to how much fall protection it provides. A thicker layer can absorb more energy and thus protect from higher fall heights. For example, data from international systems shows that different thicknesses of wet-pour can be certified for critical fall heights up to around 2.5 m, depending on the system.

How Much Fall-Height Does LawnKing’s Artificial Grass Offer?

At LawnKing, we design our playground turf solutions with safety in mind. According to our “How Artificial Grass Is Safe for Playground Surfaces” page, our playground turf meets ASTM F1292 fall-height standards. lawnking.co.za

We also emphasize our “soft-fall” technology: our turf has an added safety profile that makes it “the softest surface to fall on — even compared to real grass.” lawnking.co.za

That said, the actual fall-height protection for any specific installation depends heavily on the underlayer. When we install for schools (or daycare centres), we often combine:

A properly engineered sub-base (crusher dust or similar) lawnking.co.za
A cushioning pad (rubber or foam)
The synthetic turf itself

This layered approach ensures that children who fall from play equipment are far less likely to suffer serious head injuries, as the surface attenuates the impact.

On our Randpark Ridge page, we note that all our surfaces meet “critical fall height protection” standards. lawnking.co.za

How Wet Pour Compares to Other Safety Surfacing Options

Rubber wet pour has several advantages over alternative playground surfaces:

Durability & low maintenance: Once cured, it resists weather, UV rays, and regular foot traffic.
Customisable: You can choose colours, patterns, or even integrate logos or educational games into the surface.
Seamless finish: No joints mean fewer trip hazards and more consistent shock absorption.
Regulatory compliance: Because its critical fall height can be tested and certified, it aligns well with international standards (e.g., EN 1177) and local ones (e.g., SANS 51177).

Other surfaces, like rubber tiles or loose-fill materials (e.g., mulch, gravel), have their place — but may not offer the same seamless energy absorption or long-term performance.
