When talking about surfacing, there are several choices you can make, especially when designing a playground. You will also have to consider various factors when choosing a surface, including the budget, maintenance, area, and more.
As playgrounds should always provide protective surfacing, you must follow the safety and accessibility guidelines. When choosing a surface, remember to always ask for specifications, warranty, and maintenance guidelines, as these may vary per brand.
There are two different types of surface options for playgrounds: loose-fill and unitary. Read more to find out which of these surfaces will work best for your playground.
Loose-Fill
These forms of surfaces are cost-effective and shock-absorbing, providing extra cushioning during a fall. Loose-fill materials include wood fibers, rubber, and sand & pea gravel.
While there are many benefits to using loose-fill material, such as bring shock absorbent, this material may also pose a danger to toddlers and dogs due to ingestion. Thus, it is essential to know if this material is suitable for your playground.
As mentioned, there are three different loose-fill materials — engineered wood fiber (EWF), loose-fill rubber, and sand & pea gravel.
Engineered Wood Fibre (EWF)
EWF is an economical playground surfacing, offering many qualities such as slip-resistant, low costs, natural-looking, and more. EWF is also the most widely used playground surfacing at 75%.
EWF has a woody and fibrous consistency. When installing, it is advised to have a layer of gravel for drainage and a layer of geotextile cloth beneath the EWF surface. This EWF layer should also meet ASTM F1951 regulations. This surface is suitable for most playgrounds, landscapes, and trails.
Loose-Fill Rubber
Out of all loose-fill surfaces, loose-fill rubber offers the best impact absorbing properties. Similar to EWF surfaces, loose-fill rubber is suitable for playgrounds, landscapes, and trails.
Loose-fill rubber is also known to have the best ASTM F1292 test results and is made from recycled benefits. This means that the surface will drain well and is mold and insect resistant.
Sand & Pea Gravel
While known as a loose-fill surface, this surface does not always meet the accessibility standards or ASTM F1951. Thus, using this surface should be carefully considered. This surface can provide tactile experiences on secondary routes. However, it can have downsides, such as being a potential choking hazard.
Unitary Surfaces
Unitary surfaces are surfaces bound together and fixed in place. Examples of these surfaces include Poured-in-Place (PIP) Rubber Surfaces, Bonded Rubber, Tiles, and Synthetic Grass. Unlike loose-fill surfaces, unitary surfaces do not require raking, compacting, or replenishing; however, they may require sanitization and maintenance.
Poured Rubber Surfaces
These surfaces, also known as poured-in-place (PIP), are a popular surface choice and consist of two layers: an attenuation layer and a color wear layer. These surfaces can vary in price depending on color, size, and thickness.
This surface provides a seamless surface and has good resistance to flammability. Do note that for installation, a trained crew is necessary to help meet safety requirements.
Tiles
Tiles help provide a smooth surface to your playground. Tile can range from rubber to even aquatic and has high durability. This means that low maintenance is needed for this surface. This form of surface can be used for multiple areas, including indoor areas, due to its durability.
