Understanding septic tanks: concrete versus plastic

Did you know that concrete septic tanks tend to last a lot longer than plastic ones? Here at Septic Tank Services we only install concrete septic tanks for this reason. This is because we believe they offer our customers in Scotland and the north of England the best value for money as they often last for 40 years, sometimes even longer. Choose Septic Tank Services for a durable septic tank installed by a trusted, family-owned business serving Scotland and the north of England.

The durability of concrete septic tanks offers peace of mind for customers that once their tank is installed, with proper maintenance they shouldn’t have to worry about replacing it for decades. But that’s not the only reason we recommend concrete tanks.

Concrete septic tanks benefits

Septic tanks sit deep underground and support the weight of the soil above them. As more soil and plants are added, that weight increases alongside any rainfall before it drains away. Tanks must also withstand additional loads placed on top of them, even for short periods of time such as people or vehicles. Concrete tanks are great at withstanding this pressure, resulting in fewer cracking problems and leaks. Plastic tanks have been known to collapse in on the weight of the ground above it causing immediate problems. These can be expensive to fix.

Similarly, their weight is also a benefit when it comes to floating. If your home or business is in a high water-table area, flooding could cause problems with a more lightweight tank. A concrete one will remain stable and where it should be. A tank which moves unexpectedly can cause fractured pipes or even cracking in the tank itself. Whilst we do undertake a lot of septic system repair, we want to stop all of this from happening in the first place. This is why we only use concrete tanks.

Concrete septic tanks also avoid the use of plastic, which is becoming a large problem for the environment. Plastic can break down over time resulting in microplastics. New research tells us this is quickly becoming one of the planet’s greatest manmade disasters of our time. Plastic can also leach chemicals into the environment and water system, causing health hazards to wildlife. Concrete ensures this does not happen.
