  • Inner width 2.4 m and 2.8 m
  • Inner length from 1.9 m to 6.1 m
  • Usable volume of one tank up to 34 m³
  • Single tanks can be connected into one system and thus expand usable volume
  • Waterproof concrete C40/50 resistant to environment XA1, after request, it is possible to also make a segment for aggressive environment XA2 and XA3
  • Tanks with thickness of walls 140 mm fulfil requirements for coverage of reinforcement 45 mm for environment XF4
  • For high tanks the class of strain is D400
  • For low tanks the class of strain is B125 (green strips, constructions not compressible by vehicles, parking lots for cars), in case of other assessment also D400
  • Tanks can be filled only after they are embanked with soil

ADVANTAGES

  • Fast construction
  • Construction is possible also in unfavourable climatic conditions
  • Big usable volumes
  • Placing into gravel-sand bed is possible only in unfavourable geological conditions, we recommend placing onto a concrete baseplate
  • Compressible by vehicles without further added concrete and without structural assessment
