Infiltration module for rainwater treatment
The company Finger Beton introduced its new precast infiltration module Perco with utility model registration at the recent IFAT. This modular system for subterranean infiltration of rainwater with a compressive strength of C40/50 can be directly trafficked by heavyload vehicles and is easily installed, flat or surface-near, by excavator.
Great variety of installation due to modular construction
The modular construction enables a great variety of installation modes: The infiltration modules can be stacked and combined with standard shafts. At a standard cross-section of 1,565 x 910 mm, the modules are available in construction heights of 500, 750 and 1.000 mm. At individual weights of 425 to 850 kg, this corresponds to a volume of 308 to 616 l.
The cover slabs with integrated load transmission can be mounted dry, without mortar, and secured against displacement.
Infiltration at a high groundwater level is unproblematic. The module Perco can be fitted with an upstream sedimentation and settlement shaft and can also be used as rainwater retention basin; inspections are possible.
