Expert Guide to Choosing the Right Septic Tank Material
Nov 26, 2025

If you’re installing a septic system in a new home or upgrading to a newer and more modern system, you’ll find that septic tanks come in several materials to choose from. The most common septic tank materials include concrete, plastic, fiberglass, and steel. Each material comes with its own pros and cons, and it can be difficult to choose the right choice, especially if you’re a new homeowner. Today, A1 Septic is here to help you understand the different types of septic tanks.

Expert Guide to Choosing the Right Septic Tank Material

A1 Septic is the company to call for all your septic needs. From new septic tank installations to septic pumping and routine inspections, we’ve got you covered. Read on to learn more about septic tank types.

Concrete Septic Tanks

Concrete is one of the most widely used materials in septic systems due to its strength and longevity.

Pros:

  • Extremely durable and long-lasting
  • Heavy structure helps keep the tank securely in place
  • Resistant to most soil pressures and groundwater movement
  • Suitable for both residential and commercial applications

Cons:

  • Heavy to transport and install
  • Can crack over time due to soil shifting or age
  • Repairs can be more complex

Concrete tanks can last several decades with proper maintenance, including regular septic cleaning and pumping in Orlando, FL. This makes them a top choice for homeowners seeking long-term reliability. If your soil is prone to shifting or you have high-traffic areas nearby, concrete may be the strongest and most stable option.

Plastic (Polyethylene) Septic Tanks

Plastic tanks have grown in popularity thanks to their lightweight design and affordability. It’s common to find these tanks in modern homes.

Pros:

  • Easy to transport, move, and install
  • Resistant to corrosion and rust
  • Less expensive than concrete in most cases
  • Ideal for remote installations

Cons:

  • Not as strong as concrete
  • Can shift or float in areas with high groundwater
  • May warp or crack if soil pressure is too high

Plastic tanks work best for properties with good soil stability and easy access for installation. While durable, they are more vulnerable to damage from external pressure or heavy equipment driving above them.

Fiberglass Septic Tanks

Fiberglass is known for its combination of high strength and low weight, making it a premium option.

Pros:

  • Won’t rust, corrode, or deteriorate
  • Lightweight but extremely strong
  • Resistant to soil pressure and groundwater intrusion
  • Not prone to cracking like concrete

Cons:

  • Often more expensive than plastic
  • Can float in high-water-table areas without proper anchoring

Fiberglass tanks offer excellent longevity and structural integrity. If you’re looking for a low-maintenance septic solution, you won’t go wrong with fiberglass septic tanks. They hold up well in most soil types and climates.

Which Septic Tank Is Best?

The ideal septic tank for your property depends on budget, soil conditions, groundwater levels, and long-term expectations:

  • Choose concrete if you want maximum durability and stability.
  • Choose plastic if you need an affordable, easy-to-install option.
  • Choose fiberglass if you want a lightweight, corrosion-proof tank with excellent longevity.

It’s best to consult with a professional septic service company when you need help from an expert. Professional septic technicians will help you choose the right septic tank size and ensure it’s installed correctly.
