5 Surfaces Underneath Your Cedar Playsets to Save Your Child From Harm

If you decide to buy your kids an outdoor playset, you are going to want to make sure that they are safe. No matter how well constructed the actual playground equipment is, you cannot guarantee that there won’t be any tumbles or falls. Kids are kids, and they are undoubtedly going to take risks and push themselves in their play.

Indeed, some of the best learning experiences come from them trying out new things and extending themselves. This means that you really should think about the type of surface on which you position your outdoor playset.

A Guide For What To Put Beneath Your Swing Set

Let’s begin by stating the obvious. We do not suggest that you position your playset on concrete or asphalt. You may have space on a concrete pad in your yard, or even in a driveway, but if your child has even a minor fall, it has the potential to be very painful and even permanently damaging to their health. You still sometimes find concrete under play equipment in old public playgrounds, and the only winners here are local emergency rooms, who gain unnecessary young clients.

It is fairly common to see outdoor playsets placed directly onto a grass surface, and this is better than them being on a concrete or asphalt surface. The problem is that while grass can provide some cushioning for small bodies that fall on it and even dirt can be okay when it is loose, weather and constant use can wear out the grass cover and compact the soil. Compacted soil is, of course, hard soil.

It is good practice to have an impact absorbing surface if your kids are going to be on equipment that allows them to be more than two feet above the ground.

Child safety experts recommend that the combined height of the playground equipment and the child standing on it should be no more than 12 feet. If it is any higher than that, no surface material will effectively prevent your child from harm if there is an accidental fall from the highest point.

So, assuming that you want a safer surface under your playground equipment, what are some options you could consider?

1. Sand or Pea Gravel

Sand or pea gravel are still not perfect surfaces to keep your kids unharmed, but at least they are comparatively cheap, and they are natural, which might fit in well with your garden decor. You will need to build a border or retaining wall around the edge of the surface play area to keep the sand or pea gravel in place.

If your play equipment is less than eight feet high, 12 inches should be a deep enough fill — but don’t try and compact it. Compacted fill makes for a hard and painful surface. Your kids need loose fill to cushion them should they fall and land on the ground.

It certainly would not hurt if you added extra fill, for instance making it up to 20 inches deep, to add additional cushioning for young bodies. Your kids do need to be relatively careful in wet conditions as sand, in particular, can get hard and unyielding when wet.

One disadvantage of sand and pea gravel is that neighborhood pets may consider it a personal litter box. Sand is also light and can blow around in windy conditions, while gravel can easily spread away from the play area, requiring regular raking back into place. Sand and pea gravel are not considered suitable for children using wheelchairs.

2. Mulch or Wood Chips

Mulch and wood chips are natural solutions to your outdoor playset surface needs. These are a very popular kind of surface that are comparatively inexpensive, easy to find, and considered environmentally friendly.

Wood chips, in particular, are sturdier and likely to last longer, with little likelihood that they will blow away in the wind. Wood chips also seem less inviting to pets, so they remain clean longer. However, both mulch and wood chips are biodegradable, meaning these surfaces will eventually need replacing or topping off every 2–3 years as they compact and decompose over time.

3. Shredded Rubber

Shredded rubber is another loose fill surface that you could consider placing under your playground equipment. As with other types of loose fill material, you need to build a border frame to contain your shredded rubber, keeping the surface 12 to 20 inches deep.

The shredded rubber used around playground equipment is an effective means of recycling old tires. It costs more than other loose fills, but is cheaper than solid rubber tiles or poured surfaces. While it won’t decompose, it can be kicked around, so you will need to rake it back into position periodically around high-wear areas like under swings and at the foot of slides.

4. Rubber Mats & Tiles

Interlocking rubber mats and tiles have become increasingly popular as play surfaces in recent years. They avoid many of the issues that loose fills present — for example, pets won’t use them as a litter box, and they won’t blow away or require raking.

Tile thickness depends on the drop height of your equipment. For instance, if the highest fall point on your playset is 8 feet, your mats should be roughly 3.25 inches thick. While more expensive than loose fill and slightly more complex to install, rubber mats provide a durable, low-maintenance, wheelchair-accessible surfacing solution.

5. Poured-in-Place Rubber

Poured-in-place rubber is widely regarded as one of the safest surfaces you can choose for a playset area. It consists of two seamless professionally installed layers: a bottom cushion layer for impact absorption and a top wear layer for durability.

Although it requires professional installation and carries a higher upfront cost, poured-in-place rubber is extremely long-lasting, requires virtually zero routine maintenance, is fully wheelchair accessible, and can be customized in vibrant colors to complement your yard layout.

Other Safety Considerations

When planning your play space, remember that active play carries motion. If a child jumps or falls off a swing at peak elevation, they won’t just fall straight down — they will travel forward or backward. Because of this trajectory, your protective surfacing should extend at least 6 feet beyond the outer perimeter of the equipment on all sides.
