For septic tanks, concrete is a superior material to fiberglass and plastic. It’s watertight and heavy duty, making it ideal for both residential and commercial systems. Concrete tanks are more durable than fiberglass and plastic and their strength increases over time. What’s more, concrete resists buoyant forces better than other materials – a real benefit in areas with high ground water like parts of Umatilla County. Lastly, concrete is an environmentally sound material and doesn’t add chemicals to the ground.
