Underground tanks

CGH underground tanks can be delivered as single skineed steel tanks or as double skinned steel tanks. In most countries it is now a legal requirement to use double skinned tanks made of two layers of steel. This is the most environmentally safe way of storing chemicals, oil and gasoline products. The tank's double wall can be connected to an alarm system which ensures that leaks do not occur in one of the tank walls.

CGH supplies tanks made according to EN12285-1 in 4 standard diameters and in standard sizes up to 100 m³. For special projects we can also offer tanks in non-standard sizes and in special diameters. Send a query to learn which options we can offer.

Overview of standard diameters / volumes:

  • Diameter 1600 mm: 3 m³ - 5 m³ - 8 m³ - 10 m³ - 13 m³ - 16 m³
  • Diameter 2000 mm: 10 m³ - 13 m³ - 16 m³ - 19 m³ - 25 m³ - 30 m³

For further details see our product sheet.

If necessary, the tank can be divided into several rooms with the possibility of storing several different products in the same tank.

Our factory has its own painting department, which gives the tank the desired surface treatment internal and external. On the outside, the tank is treated with an approved polyurethane paint that ensures the corrosion protection.

Internal treatment protects the tank against corrosion and thus prolongs the life of the tank. If the tank is 100% internally treated, it is also ensured that the product in the tank remains completely clean. CGH offers a wide range of surface treatments that cover almost every need. We have paint for heating oil / diesel, gasoline, bio fuel and a wide range of chemicals. Inquire about a resistant paint for the product you want to store.

For aggressive media, CGH underground tanks can also be delivered as stainless steel tanks. Underground tanks can be made as single skinned tanks made entirely of stainless steel, but we also offer a special double skinned version, where the inner tank is made of stainless steel and the outer tank is made of ordinary steel. The outer tank is surface treated as normal with a protective paint. This combines the best features from stainless steel tanks and traditional tanks. All at a lower price than a completely stainless tank.

CGH undeground tanks can be supplied with a variety of different accessories, including descent shaft, streetcovers and anchorage. The tanks can also be supplied with insulation and heating if the product in the tank is to be kept at a certain temperature.

Our production is ISO 9001 certified by TÜV.
