Pros & Cons: Using Sand as a Playground Surface

March 31, 2021

Sand has been a universal element in playgrounds and parks for decades. There are many exciting activities people associate with sand, from constructing sandcastles to leaping around with friends. In recent years, the safety of sand as a playground surface has been called into question. Is sand a really safe option for a playground? Can you use other surface options in place of sand? While we prefer poured-in-place surfacing, we still want to provide you with all the information you need to make a decision. We prepared a thorough review of sand for playground surfaces, examining the pros and the cons.

What is sand for playground flooring?

Sand is a loose granular substance or sediment, generally pale yellow or brown, produced by the erosion or weathering of rocks and minerals. The composition of sand can vary based on local rock sources and conditions, making a range of colors like pale yellow, brown, white, black, green, and even pink. Commonly found blanketing beaches, riverbeds, deserts, and playgrounds, playground sand brings a natural esthetic often associated with fond childhood memories.

Sand has to have a depth of approximately 12 inches to meet ASATM requirements

Safety and Accessibility of Sand as a Playground Surface

Pros:

  • Sand is deemed an appropriate surface for playgrounds by the American Society of Testing and Materials if you layer the sand to a depth of about 12 inches.
  • With safety in mind, manufacturers of playground sand submit the sand to various measures to protect children’s welfare. First, they wash the playground sand to remove unwanted debris, bacteria, or other minerals.
  • The sand is also water pressurized to round out and smoothen any larger, sharp particles. Then it’s submitted to a sieve analysis to evaluate and assess particle size distribution.
  • Sand doesn’t easily support microbial growth, making one less thing to worry about.

Cons:

  • Sand is one of the less effective materials regarding impact absorption.
  • You’ll need more of it to achieve safety requirements. To ensure sand offers proper fall protection for children, the National Safety Council (NSC) recommends maintaining a 12-inch depth in areas where equipment requires a six-foot drop or fall zone. The NSC requires a 9-inch depth in areas with a four-foot fall height. That’s a lot of sand.
  • Sand also doesn’t meet the Americans with Disabilities Act’s accessibility standards.
  • It can be difficult for people with disabilities to navigate, particularly wheelchairs.
  • One of the biggest dangers of sand is the possible presence of asbestos and silica. Silica can cause asthma and inflammation of the lungs, where asbestos fibers can cause cancer. The play sand you select should be thoroughly tested by manufacturers.

Cost of Sand as Playground Flooring

Sand is a relatively inexpensive option up front, however it does require ongoing replacement and refill costs.

Pros:

  • Sand is one of the cheapest options for playground surfaces.
  • Sand typically costs $1.50 to $3.00 per square foot.
  • At $2.00 per square foot, a 2,500 square foot playground could cost about $5,000 for sand.
  • Hiring a professional installer will be an added cost, but it should take less than a full day to install the sand. While you can opt to install it yourself, you don’t get the work guarantee that comes with a pro.

Cons:

  • The lifetime cost of sand can start to add up.
  • You’ll need to replace the sand once a year, especially in high-traffic areas.
  • If you want to keep your playground sand clean and play-ready, expect to pay to refill at least 25% of the sand each year, or about $1,250 or more for a 2,500 square foot playground.

Quality and Maintenance of Sand as a Playground Surface

Foreign objects, weeds, animals, etc can make sand difficult to maintain for playgrounds.

Pros:

  • Unfortunately, when it comes to outdoor playground flooring, the quality and maintenance of sand don’t contain very many positives.

Cons:

  • Sand can be pretty challenging to maintain.
  • It attracts animal waste and insects.
  • Sand is also messy and easily tracked indoors on clothes, hair, and shoes.
  • You should replace the sand every year or more frequently if necessary.
  • As kids play in the sand, it will move around significantly.
  • Plus, you never know when you’re going to find something harmful buried in the sand. Therefore, you should rake the sand weekly into a level uniform surface at a depth of 12 inches and inspect it for foreign objects.
  • If the area you live in is often dry or windy, you may want to rethink sand. Nobody enjoys dust and sand particles blowing in their eyes.
  • In cold or wet weather, sand tends to compact into an unsafe, more solid surface.

Installation Sand for Playground Flooring

To keep sand in your playground area, you’ll need a fixed border installed.

Pros:

  • One significant positive to sand is that it’s relatively easy to install.
  • You can easily find sand at your local hardware store. Look for Minus 30 play sand, as it’s thoroughly tested and rated for safety.
  • When it comes to site prep sand is one of the more straightforward surfacing options to install.
  • As with most playground installations, ensure the area is level and even, free from rocks and debris, and deep enough to accommodate the fall depth, at least 12 inches in the case of sand.
  • As with most loose-fill surfacing options, you’ll need a retention area or fixed border to keep the sand in place.
  • A sub-grade of about 3 inches of loose-fill pea gravel may also be necessary for drainage.

Cons:

  • Not all sand is created equal. Particular sand can contain harmful materials, making it extremely important to select sand explicitly made for playgrounds.
  • Wash plaster sand, commonly used in mason projects, maybe okay for private school or residential playgrounds with minor usage. However, it’s not the best option for a heavily used playground.

Next Steps

Playground flooring is an important factor for children’s safety when playing on the equipment, making surfacing material one of the most crucial playground construction factors. Sand isn’t the only surfacing option out there. Consider poured-in-place surfacing for a comfortable, soft cushion for playing and an ADA-compliant option for your playground.
