Horizontal Storage Underground Tanks

Tunetanken Horizontal Storage Underground Tanks are solid storage solutions well-suited for a range of different purposes. Horizontal Storage Underground Tanks can endure being below ground for many years. Our Horizontal Storage Underground Tanks are produced in a strong composite material that make them resistant to exhausting conditions such as extreme loads from soil pressure and corrosion. Our tanks are a great solution for the environment as the risk of leakage is minimised.

Tunetanken Horizontal Storage Underground Tanks are well-suited for a range of purposes such as storage of chemicals, rainwater, process water, wastewater, or petrol and oil products.

We always customise our underground tanks to meet your requirements for operation conditions and whatever content you wish to store. Despite the great strength of the material, the tank has a low weight and together with the fully moulded design, it makes mounting easy. We have developed a special uplift resistance edge securing the tank stays safe and stable in the ground.

Due to our expertise, the newest composite materials, and high demands for quality, we produce our below ground tanks to secure your tank and investment for the future.
