Retention roof Contec.retention

Water accumulation or compliance with specified water quantities, Contec.retention.

Peak runoff values break during heavy rain events or water retention on the roof instead of expensive retention basins. The choice is yours.e

Contec.retention throttle - water accumulation

With the system Contec.retention throttle you accumulate water on the roof or on traffic roofs. It is suitable for slope-free extensive and intensive green roofs.

Advantages

  • Low weight
  • Increased evaporation capacity
  • High ecological value
  • Relief of the sewerage system
  • Easy to install
  • Great design opportunity in the construction

  • Color: Black
  • Nominal thickness: 30 mm - 150 mm
  • Weight: Approx. 3.6 - 12 kg/m2
  • Water storage: Approx. 80 - 140 l/m2

Contec.retention meander - discharge delay

With Contec.retention Meander you can achieve either runoff retardation or water retention. This system is for extensive green roofs or for gravel roofs.

Advantages

  • Top values of the runoff coefficient
  • Low installation height
  • Delayed water drainage during heavy rain event
  • Easy to install
  • Excellent values
