Concrete and poly septic tanks are two of the best choices when it comes to septic tank installation. While having two great options to choose from isn't a bad thing, careful consideration is vital to ensure you pick the best septic tank type for your needs.
Here's what you need to know about each type in order to identify the best option for you.
Concrete Septic Tanks
Of the two septic tank options, concrete tanks have been around longer. They're made of high-quality concrete and are the go-to choice for many homeowners for a variety of reasons.
Concrete septic tanks generally have a longer lifespan than their poly cousins due to concrete's superior strength and resilience. A waterproofing coating is applied onto the internal walls of these tanks to prevent leakage and to maintain the structural integrity of the tanks. With a proper maintenance regimen in place, your concrete septic tank can last for several decades to come.
Also, concrete septic tanks tend to come in larger sizes because they're generally stronger and can hold more wastewater than equivalent tanks made of plastic. If you have a big family and need a tank that can handle your residential wastewater flow rate, a concrete septic tank is an ideal choice. Larger tanks take longer to fill, thus reducing the frequency of tank pump-outs.
On the downside, concrete septic tanks are generally more expensive to install than plastic septic tanks. Plus, concrete septic tanks may develop cracks over time, thus leaking wastewater on your property. This will compromise your family's health as well as public health.
Poly Septic Tanks
Also known as polyethylene septic tanks, these tanks appeal to homeowners that are looking for a cheaper alternative to concrete septic tanks. They're also a perfect solution for people looking to avoid notorious problems associated with traditional concrete, such as cracking and wear of the tanks' interior waterproofing coating.
Pitted against concrete tanks, poly tanks are generally a lot cheaper to install. These tanks weigh less than comparable concrete tanks, and this quality makes them easier to install.
On the downside, plastic septic tanks aren't usually designed to handle high flow rates and may not be suitable for larger households. If they were to be used in homes requiring a larger installation, they would turn out to be a false economy. Plus, they can't match the sturdiness and longevity that comparable concrete tanks provide. While poly tanks are generally cheaper to install, they're certainly not as cost-efficient as their concrete alternatives over the long-term.
Choosing an ideal septic tank for your home can be a confusing and frustrating task. Based on the information provided above, choose a tank type that best matches your home plumbing requirements. If you need help with choosing between the two options, feel free to seek a specialist's advice.
