What’s the Difference Between Plastic & Concrete Septic Tanks?, Emmons, North Carolina

Septic tanks process and manage waste without connections to municipal sewer lines. If you’re considering installing one in your property, you’ll have many options for their materials. Two of the most popular ones are concrete and plastic. Understanding the differences between these units will help you decide which one to pick. To ensure you make the best choice for your needs, here’s a comparison between them.

Plastic vs. Concrete Septic Tanks


Plastic tanks, which are made of polyethylene, tend to be cheaper than concrete ones. This not only goes for the product, but also installation, since the units are quicker to place underground and weigh much less. They are watertight and completely resistant to water-based corrosion. They’re also a lot more flexible than concrete, meaning they won’t crack easily.

However, these tanks are not as sturdy as concrete and can be crushed from heavy weights. If you plan on driving over the septic area, this may not be the best product for you. Their materials also tend to break or warp due to changes in soil conditions or vibrations. Compared to concrete tanks, they are more sensitive and susceptible to environmental damage. They may last up to 30 years.

Driving over the soil where the tank is buried and tree root growth are less likely to affect these units than plastic ones. Due to their resilient nature, they require much less maintenance.

On the other hand, these products and their installation cost more. They are also more susceptible to moisture-related corrosion and cracking due to cold weather as they age.
