Plastic splash blocks are a cost-effective and versatile option for homeowners. They are lightweight, easy to install, and provide quality water drainage away from the home. However, their lightweight construction also presents a disadvantage: they may be displaced by heavy rains, mowers, leaf blowers, or trimmers. So, do plastic splash blocks stay in place? The answer is that it depends on various factors, including weather conditions, the weight of the block, and whether it has been correctly installed beneath the downspouts. While some sources suggest that plastic splash blocks can blow away or be moved by rodents, others assert that movement is rare, and any displacement can be easily corrected by placing the block back in position.

Plastic splash blocks are lightweight and easy to install
Plastic splash blocks are a great option if you're looking for something lightweight and easy to install. They are a good choice if you want to avoid the heft of concrete blocks, which can weigh up to 110 pounds for a 4-foot block. In contrast, plastic blocks are lightweight and easy to carry around your yard, making installation a simple and fast process that can be done without assistance.
The versatility of plastic splash blocks is another advantage. They come in a wide variety of shapes and sizes, allowing homeowners to find the most aesthetically pleasing option for their garden. You can even find plastic blocks in different colours to better blend into your landscape. This variety ensures that you can find a block that accommodates your specific needs and preferences.
However, it's important to consider the potential downsides of plastic splash blocks due to their lightweight construction. Heavy rains, lawn mowers, leaf blowers, or trimmers could potentially move the blocks from their correct positions, impacting their effectiveness in directing water away from your home. Additionally, plastic splash blocks may be more prone to damage from lawn care equipment and less durable than their concrete counterparts.
If you're concerned about the stability of plastic splash blocks, there are a few solutions you can consider. Some people suggest building up the soil under and beside the blocks to provide more support. Another option is to drill small holes and pin the blocks down with landscape or camping stakes. These measures can help ensure that your plastic splash blocks remain securely in place.

Plastic blocks may not stay in place in heavy rain
Plastic splash blocks are a popular choice for homeowners due to their low cost, lightweight, and versatility. They are easy to install and come in a variety of shapes, sizes, and colors to suit different needs and preferences. However, one of their main disadvantages is their lightweight construction, which makes them prone to displacement during heavy rainfall.
While plastic splash blocks provide quality drainage and protect your home's foundation from water damage, their position may be affected by heavy rains, leading to issues with water channeling. This is a significant concern as it can result in water pooling around your home's foundation, potentially causing flooding or water damage.
The lightweight nature of plastic splash blocks makes them susceptible to being moved not only by heavy rainfall but also by strong winds, lawn care equipment, and even rodents. This can be a significant issue if the blocks are not promptly moved back into place, as it can render them ineffective in properly diverting water away from your home.
To mitigate this issue, some homeowners choose to secure their plastic splash blocks by digging indents for them to sit in or pinning them down with stakes. These methods can help prevent unwanted movement and ensure the blocks remain in their correct positions. However, it is important to note that even with these measures, plastic splash blocks may still be more prone to displacement than their concrete counterparts due to their lighter weight.
If you are concerned about the potential for displacement during heavy rain, concrete splash blocks might be a more suitable option. Concrete blocks are heavier and more durable, ensuring they remain firmly in place even in harsh weather conditions. While they may be more expensive and challenging to install, concrete splash blocks offer a long-term solution that requires minimal maintenance and provides reliable protection for your home's foundation.

Concrete blocks are heavier and more durable
Concrete blocks are a much more robust solution and are approved for road usage, unlike plastic barriers. Concrete is a dense, stable, and versatile material that is perfect for barrier usage, especially when a physical, immovable barrier is required. Concrete blocks are ideal for long-term use and can be used as temporary barriers, flood defences, traffic barriers, and parking guidance. They are also simple to transport.
Concrete blocks are made from high-strength concrete and are extremely durable, lasting years with no maintenance. They are manufactured with 8,500-psi concrete to meet the highest quality and durability standards with a maximum of 6% absorption rate. They can withstand harsh weather conditions, saving you money on maintenance and repairs over time.
Concrete splash blocks are also attractive additions to home exteriors, serving as decor that complements other landscaping and hardscaping in your yard. They are also cost-efficient, preventing soil erosion, avoiding mud splatters, and keeping your foundation safe from water damage.
While plastic blocks offer initial convenience and ease of use, they have limited durability and stability issues. They are lightweight and easily movable, which can be a disadvantage as they may be displaced by lawn care equipment, heavy rains, or even children running around.

Plastic blocks are versatile and come in different colours
Plastic splash blocks are a versatile option for homeowners. They are lightweight, easy to install, and come in a wide variety of shapes and sizes. However, their lightweight construction can also be a disadvantage, as they may be displaced by heavy rains, lawncare equipment, or even rodents. To mitigate this issue, some homeowners choose to pin the blocks down or build up the soil around them.
Plastic blocks are commonly used in children's toys and educational tools, where their versatility is a significant advantage. They can be moulded into a wide range of shapes and sizes, and come in various colours, including transparent hues that mimic the look of real ice. This makes them perfect for open-ended learning and play, allowing children to explore their creativity and develop fine motor skills.
The colour of a plastic block is often as important as its shape. Colour can be used to create unique designs, enhance sensory play, and improve the overall appearance of the block. For example, the unique waffle design of some plastic blocks is enhanced by using light blue, moss green, and other natural tones. These colours are not only visually stimulating but also help children develop colour and shape recognition skills.
For more advanced builders, plastic blocks can be made to look like real-world materials such as glacier bricks, breeze blocks, stone, and brick wall boulders. This allows children to design and build structures using materials that resemble those used in construction. The variety of colours and shapes available makes plastic blocks a versatile option for educational and entertainment purposes.
In addition to children's toys, plastic blocks are also used in seasonal decor and custom handmade pieces. The customisability of plastic means that unique colours and designs can be created to meet specific requirements. Whether it's a standard colour, a custom blend, or a transparent hue, plastic blocks offer a wide range of options for consumers.

Concrete blocks are more expensive to ship
Concrete splash blocks are heavier and more durable than plastic ones, but they are also more expensive to ship. Concrete blocks are made from high-strength concrete and can withstand harsh weather conditions, heavy rains, and strong winds without moving or blowing away. They are a long-term solution that can remain in place for years with no maintenance, saving you money on repairs over time.
On the other hand, plastic splash blocks are lightweight and easy to install. They come in a variety of shapes and sizes to accommodate different needs and can be purchased at a lower cost. However, their lightweight construction also leads to potential issues. For example, they may be more susceptible to damage from lawn care equipment or heavy rains, which could cause them to move from their correct positions.
The weight of concrete splash blocks is often seen as an advantage as it ensures the blocks remain firmly in place once installed beneath the downspouts. In contrast, the lighter weight of plastic blocks may require additional measures to keep them in place, such as digging indents for them to sit in or pinning them down with stakes.
While concrete blocks may be more expensive to ship due to their weight, they offer a durable and low-maintenance solution for water drainage. Plastic blocks provide a more cost-effective and versatile option but may require more effort to maintain their correct positioning. Ultimately, the choice between concrete and plastic splash blocks depends on factors such as budget, ease of installation, durability, and long-term maintenance considerations.
