2.Material

1.Wooden material

Appearance:

The appearance of wooden materials is mostly brown, with a natural beauty, which can match most applicable scenes and is suitable for scenes surrounded by green.

Safety:

Wooden materials are mainly composed of splintered wood, with strong shock absorption effect. 9-inch wooden materials can prevent falls up to 7 feet. On rainy days, wooden materials will also absorb moisture and discharge moisture during dry periods, which has a certain degree of anti-slip properties.

Cost:

Wooden materials are easy to obtain, so the initial cost is low, and the installation is also simple, just covering it. However, the subsequent maintenance cost is high and needs to be replaced every year.

Maintenance:

Wooden materials are difficult to maintain because they are made of organic materials and are easily corroded by mold and insects. At the same time, wooden materials are not very stable and may spread to other parts of the yard when children are playing, so they need to be cleaned up in time.

2.Sand

Appearance: Most of the sand is white and has a natural beauty. If it is surrounded by green plants, it may stand out.

Safety:

 Sand is not very cushioning and can only provide easy protection. In terms of impact absorption, 9 inches of sand can only prevent a fall of up to 4 feet. At the same time, sand does not meet the American Accessibility Standard (ADA) and is difficult for people with disabilities to pass through.

Cost:

Sand is relatively cheap, easy to collect and simple to install. Like wood, it may be more troublesome in later maintenance. You need to be prepared to clean the site and fill it with sand regularly.

Maintenance:

 Sand is time-consuming and difficult to maintain. Children’s toys or various small items may fall into the sand, and sand will attract some insects and animals, which will bury feces in the sand and hide harmful materials or objects. Sand is also very easy to scatter everywhere when children play.

3.Grass

Appearance:

 Grass is very beautiful and can blend into the surrounding landscape.

Safety:

Grass is the lowest safety and is not even suitable as a cushioning material. Grass is very susceptible to wear and tear. Children’s footsteps can damage the grass, further weakening its shock absorption ability and not providing much fall protection. Grass is also slippery in the morning or after rain, which can easily cause children to trip and get injured.

Cost:

Almost no cost, but the maintenance cost is high and it is expensive to use for a long time.

Maintenance:

 Grass needs to be maintained frequently, and it needs to be mowed constantly. Grass also encourages the growth of pests and mold, and may need to be disinfected. Watering and fertilizing are also required after the grass is damaged.

4.Stone/Pea Gravel

Appearance:

Pea gravel is composed of small stones and has a natural appearance. It is usually used in gardens and dog parks.

Safety:

Pea gravel is not very safe. A 9-inch pea gravel can prevent a 5-foot fall. It is also not ADA-compliant and is difficult for people with disabilities to pass through.

Cost: 

The initial cost of pea gravel is not high, but the subsequent maintenance cost is high. Some pea gravel may be damaged during use, or it may be scattered during play and needs to be filled in a timely manner.

Maintenance:

Pea gravel does not require high maintenance in the later stage. It absorbs water when it rains, and the surface is not smooth. It can also inhibit the growth of weeds and will not attract other animals. Children may play out of curiosity, causing the stones to scatter everywhere, so they only need to be filled in time.

5.Rubber mat

Appearance:

The appearance of the mat composed of rubber can be freely designed by you, and the appearance color can be freely selected. Generally, the lighter the color, the better.

Safety:

As long as the rubber mat meets the standards of the American Society for Materials and Testing (ASTM), high-quality rubber mats can improve the cushioning force and can greatly absorb the impact of falling. In addition, rubber will be hotter under the sun, and a sunshade can be placed on the site in summer.

Cost:

The cost of rubber mats varies greatly depending on the quality and the manufacturer, but in general, they are more expensive than wood materials and pea gravel, with higher initial costs and lower later maintenance costs.

Maintenance:

Rubber mats have low maintenance costs and are relatively stable. They are not affected by rain or corrosion by plants and animals, so they do not need to be maintained frequently. Simply clean and replace damaged parts.
