Underground cylindrical tanks set into concrete are used where it is not possible to place a self-supporting underground tank. When set into concrete, the tank works as permanent shuttering. This means that they are especially well-suited for use under roads or near foundations, and hence must be completely set in concrete.

Detail information

Plastic non-self-supporting underground tanks are designed with an emphasis on their excellent resistance to external influences and long-term reliability. These tanks provide a safe and efficient solution for storing a variety of liquids and meet high standards for environmental protection.

One of the key factors in the durability of plastic non-self-supporting underground tanks is the quality of the materials from which they are made. Modern plastic materials are highly resistant to chemicals, corrosive effects and mechanical stresses, making them suitable for long-term storage of liquids without the risk of leakage or soil contamination.

Frequently asked questions

This is just another name for a technical water tank, including rainwater tank, which is used to hold water and then use it. Retention tanks are distinguished between self-supporting and non-self-supporting tanks, and according to the material, most often concrete and plastic retention tanks.

The size of the rainwater tank depends on several factors that you should consider when determining the appropriate size of the rainwater tank:

  • Roof size: the area of the roof from which rainwater will subsequently be discharged into the retention tank is the determining factor. The size of the area and the average rainfall in the area are calculated as part of the calculation of the expert opinion for the "Rainwater harvesting" grant.
  • Climatic conditions: the amount of rainfall in the area where the rainwater harvesting areas are located.
  • Water consumption: you need to think about how you want to use rainwater? Will it be used only for watering the garden, flushing the toilet, washing the car or for other purposes? According to this, it is advisable to determine how big a rainwater tank you need.
  • Length of the dry season: if you live in an area with long periods without rainfall, you will need a larger rainwater tank to be able to "store" more water for the dry season.
  • Available space: how much space do you have available to install a rainwater tank
    How much space do you have available for rainwater harvesting? This is also a consideration when deciding how large a rainwater tank to install
    to choose.

It is important to make a detailed calculation based on your specific situation and needs. You should also consult with a water or ecology expert to help you decide on the appropriate size of the rainwater tank.

Standard plastic tanks and sumps have several main advantages over concrete ones.

Plastic tanks and sumps have less weight than concrete structures. This makes them easier to transport, handle and install.

Plastic tanks and sumps are resistant to corrosion and erosive processes, making them suitable for storing or processing aggressive chemicals or other corrosive substances. Concrete may be sensitive to certain chemicals and may require protective coatings or other treatments.

If the focus is on durability, then plastic tanks and sumps typically have an equal or longer service life. They are resistant to weather effects such as temperature and humidity changes and are not prone to cracking and material destruction, which affects their strength and functionality.

Plastic tanks and sumps do not require as much maintenance as concrete structures. The plastic material is smooth and does not absorb substances, making it easier to clean and remove debris.

Plastic tanks and sumps are usually cheaper to manufacture, transport and install than concrete tanks.
