What Options Do I Have For Septic Tanks?

Today, homeowners have a few different options when it comes to installing a septic tank. The most common types that you will find are concrete, plastic, and fiberglass. While each has its own pros and cons, we want to make sure people fully understand what they are getting with each product.

Concrete Tanks

Concrete tanks are a tried and true standard. They are heavy, durable, and can be made water-tight. Because of the concrete’s density, there is greater resistance to buoyancy. With being so dense you don’t have to worry about your septic tank floating or shifting over the years. If a septic tank floats it can cause a multitude of problems beyond damaging your tank. Concrete tanks are also available in a wide range of sizes and can include larger capacities. They have less stringent installation requirements and are easier to customize based on your individual needs. Our concrete tanks are pre-cast at our facility and delivered to your home for installation. They can even be moved or relocated to a new location many years down the road. Moving your fiberglass or plastic tank wouldn’t be an option. You don’t have to worry about your concrete tank rusting or breaking down like you would with other types. Concrete tanks will also withstand internal and external pressure much better than the plastic or fiberglass alternatives. Overall concrete tanks are usually cheaper, more durable, and are of better quality than fiberglass or plastic.

Fiberglass Tanks

While fiberglass tanks are lighter and easier to physically install, they require a very careful installation process in order to protect the fiberglass from being damaged. Fiberglass tank walls are only ⅛” to ¼” thick whereas concrete tanks are 2 ½” to 6” thick. Because these walls aren’t as thick and they aren’t as durable as concrete, you cannot place them where they are underneath anything or might be driven over. Also, fiberglass tanks are more prone to float than concrete tanks because of their lightweight. Being more prone to floating, you risk damaging your plumbing and entire septic system. Fiberglass tanks are harder to find and come in a limited size range, making them not a reasonable option for many people.

Plastic Tanks

Just because you can find these tanks at the box stores, doesn’t mean they are your best option. With a plastic tank, you are much more likely to experience floating or shifting over time. This is because plastic tanks are much lighter and less durable. With them being less durable if they aren’t installed properly, the side walls can buckle and collapse. With plastic tanks, you are more limited on where you can place them. You have to be sure that nothing will sit or drive above the tank, or else you risk damaging it. Plastic tanks are also prone to having their lid openings warp and misshape. This will cause the lid to not go back on properly and will greatly reduce the life of the system.
